A new glass-ceramic coating material on nickel based super alloy substrate had been found, the glass¬-ceramic coating material was developed from a glass based on MgO–Al2O3–TiO2 system. The coating material was characterized through X-ray diffractometry (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), hardness, thermal expansion coefficient testing. XRD analysis of the coating materials and the resultant coatings showed presence of a number of microcrystalline phases. SEM micrographs indicated microstructure of the material. Optical micrographs showed smooth glossy impervious free surface with defects. Hardness analysis showed the glass-ceramic coating material had higher microhardness. The thermal expansion coefficient of the nimonic alloy was much higher compared to the coating material at specific temperature.

This research aims to determine the effect of ceramic substrates surface roughness on the deposition of silver-titania (AgTiO2) coating. The ceramic substrates were prepared from three batch mixture of waste glass namely transparent glass (99 wt. %): carbon black (1 wt. %), green glass (85 wt. %): ball clay (15 wt. %) and transparent glass (85 wt. %): ball clay (15 wt. %) deposited with AgTiO2 using sol gel dip coating method. Ti and Ag phases have been identified via glancing angle X-Ray diffraction analysis (GAXRD). The thickness and morphology of coatings were characterized using Scanning Electron Microscopy (SEM). Analyses conducted have confirmed that AgTiO2 coating layers have been successfully deposited into various types of selected ceramic substrates. Microstructure analysis shows that coatings deposited on ceramic substrate with a moderate surface roughness of 2.13 (green glass: ball clay) produced the most homogeneous surface and uniform thickness.

Currently, the ceramic inner container draws great attention in the field of induction heating pot. Based on the traditional roll-forming process for ceramic pot, a new kind process was proposed to fabricate ceramic inner container and synchronously embed stainless steel plate by one-step high temperature sintering. The key technology for this process is to avoid the oxidation of SUS430 stainless steel plate during the high temperature sintering for a longtime by coating a glass-ceramic layer. In this research, the glass-ceramic coating with excellent high temperature oxidation resistance was optimized. The influences of ZrO2 content in the coating slurry on the high temperature oxidation resistance and thermal shock resistance of SUS430 stainless steel plate with glass-ceramic coating were studied. Meanwhile, the coatings were characterized by Scanning Electron Microscopy, X-ray Diffraction and Thermal Expansion Analysis. The experimental results showed that the glass-ceramic coating was smooth and had excellent thermal shock resistance when the addition of ZrO2 reached 15wt%. The mass gain of the SUS430 stainless steel plate with glass-ceramic coating was only 0.453% after sintering at 1300°C for 10h in air atmosphere, which was less one percent than that of SUS430 stainless steel plate under the same sintering condition.

Contact-induced radial cracking in ceramic coatings on compliant substrates was analyzed recently. Radial cracks initiate at the coating/substrate interface beneath the contact where maximum flexural tension occurs, and an analytical expression for the onset of radial cracking in monolayer coatings was formulated on the basis of the classical solution for flexing plates on elastic foundation. In the present study, the analytical expression was derived for the case of ceramic bilayer coatings on compliant substrates, which have significant applications in the structure of dental crowns. It was found that the analytical solution for bilayer-coating/substrate systems can be obtained from that of monolayer-coating/substrate systems by replacing the neutral surface position and the flexural rigidity of monolayer coating with those of bilayer coating. The predicted critical loads for initiating radial cracking were found to be in good agreement with existing measurements and finite element results for glass/alumina, glass/glass-ceramic, and glass/Y2O3-stabilized ZrO2polycrystal bilayers on polycarbonate substrates. Limitations of the present analysis are discussed.

Dense, crystalline, glass-ceramic coatings containing calcium metaphosphate and aluminum phosphate were prepared on aluminum oxide substrates by a three-step method. The processing involved glass (40 mol% CaO, 10 mol% Al2O3, 50 mol% P2O5) formation, deposition of a glass particle coating, and heat treatment to sinter the glass and crystallize the phosphates. Sintering and microstructure evolution were influenced by wet coating thickness, heat-treatment temperature, time, and heating rate. Heat treatment for 1 h at 725 °C using a 50 °C/min heating rate was found to give a dense, crack-free coating. The resultant coating microstructure has spherulitic morphology (0.3 μm size) with aluminum phosphate in the center of the spherulite. The hardness of the fully crystallized glass-ceramic coating was ∼5.2 GPa.

Now the oxidation-resistant glass-ceramic coatings have been widely used in reducing surface oxidation of Ti alloys during heat process. In present investigation, a lead-free glass-ceramic coating with wider protection temperature range was developed to protect Ti-6Al-4V alloy from oxidation. The phase compositions of the present coating and the oxygen distributions in the surface layers of Ti-6Al-4V specimens were investigated by means of XRD, as well as the metallographs of cross-section were observed and the depths of oxidized layers were determined by microhardness analysis. The results show that the present glass-ceramic coating can provide the oxidation-resistant effect over the temperature range of 500-1000oC in ambient air, with an environmentally friendly lead-free coating composition.

The surface of a porous silica ceramic substrate was coated with water impermeable lithium aluminosilicate glass-ceramic layer by sintering a slurry consisted of fine glass powder. The coating was 600~800 microns thick. It is demonstrated that the glass-ceramic coating consists of β-Li2Al2Si3O10 crystallites. The coated sample has an excellent water proof performance. After the coating, both the dielectric constant and loss increase. The coating protected the substrate from ablation under 1700°C.

Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes. This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate). Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.

Given the development of new heat-resistant nickel alloys that operate at temperatures up to 1,250 °C, as well as the introduction of additive technologies for the production of various parts, it is a relevant task to devise new compositions of highly heat-resistant coatings. Determining the influence of the phase composition of glass-metal-ceramic coatings on its basic properties could improve the effectiveness of protecting those parts that operate under extreme conditions. Therefore, it is promising to conduct a study aimed at establishing the relationship between the microstructure and phase composition of glass-metal-ceramic coatings and the main physical-technical characteristics. This study's results have established that the most high-quality coatings were obtained on the basis of non-crystallizing glass. Such glass is characterized by a temperature coefficient of linear expansion of 92·10-7 degrees-1, a glass transition temperature of 625 °C, and surface tension of 260·10-3 N/m at 850 °C. These properties contribute to the formation of a defect-free coating, providing uniform spreading and high-quality adhesion to the substrate. The resulting optimal coating is characterized by the adhesion strength of 98 %, the thermal resistance (mode 950↔20 °C) of 50 cycles, and the high heat resistance (a weight gain after 100 h in the temperature range of 1,000‒1,050 °C) of 0.03 g/m2·h. Coatings with a minimum amount of glass bonding are distinguished by uniformity and high quality. The optimal ratio of phases "glass:metal-ceramic composition" is 10:90. The structure of the recommended coating is uniform, characterized by the homogeneous distribution of components, the absence of cracks, visible defects, and high quality. The phase composition of the coating after firing is represented by crystals of metallic nickel and silicon, as well as a small amount of residual glass phase.

AN ABSTRACT OF THE DISSERTATION OF TITLE: (OPTIMIZATION PROTECTION OF CARBOB-CARBON COMPOSITES DISC-BRAKES MATERIAL BY COATING WITH ANTI-OXIDANTS) Developing glass enhancer mixture solutions (Ki’s), which promote the formation of a stable glass layer, homogenous clear liquid solution, and low viscosity liquid form, are easy to apply, and penetrating. They are compatible with ceramic liquid glass based anti-oxidants for treating surfaces of carbon/carbon composites material, and significantly increase the rate of protection against oxidation. Ki’s’ are comprised of mixing chemical compositions at standard temperature and pressure conditions from group one and two such as Na, K, Ca, Mg, etc. of 5 to 25 wt. %, deionized water from 95 to 75 % by weight, and adding up to 1 % by weight of surfactants such as DF-16, DF-20, and CF-10 with specific proportions, and followed by thorough stirring to produce a homogeneous blend of mixture solution. The glass enhancers, which are aqueous mixture solutions, are applied to the surfaces of carbon/carbon (C/C) composites by dipping, brushing, spraying, or other painting application techniques, followed by annealing, or a heat-treating range of 80 to 110 ℃ for a minimum of 8 hours, and allowing cooling time of the coated C/C composites of a minimum of 12 hours to room temperature. Preferential compatibility of the glass enhancer mixture solutions (Ki's) is with liquid glass former's, anti-oxidants comprised mostly of borate and phosphate glasses. The glass enhancer solution mixtures (Ki’s) are supplemental additions to ceramics’ liquid anti-oxidants coatings used for carbon-carbon composites protection against oxidation, and it will increase the rate of protection against oxidation for low, and moderate temperature’s range from 400 to 900 ℃. The glass enhancer Ki’s mixture solutions should be used with liquid glass former's’ anti-oxidants, such as SiO₂, GeO₂, B₂O₃, and P₂O₅. A series of glass enhancer’s Ki’s, heat treatment cycle (char-cycle) ranged between 700 to 900 ℃, and application methods, were developed and tested experimentally. Two arbitrary isothermal temperatures of 650 ℃, and 871 ℃ were selected for thermal oxidation testing, and a temperature of 650 ℃ was selected, and tested against catalytic thermal oxidation. Additions of glass enhancer Ki’s improved protection of C/C composites disc-brakes against oxidation by double, and triple amount of time in hours versus the use of anti-oxidant coatings alone.

An investigation was conducted into the coating of metal substrates with a glass-ceramic enamel. Two metal types were coated, a 17% chrome-iron and a low carbon mild steel. The glass-ceramic was based on a complex lithium aluminosilicate glass. The enamel was applied using a vitreous enamelling coating technique, followed by conversion to a glass-ceramic. The coating process strongly influenced the microstructural form developed. For both metal substrate types it was possible to produce coatings which wet well and exhibit good adhesion. Crystalline substrate oxide is observed at the interfaces of these coatings. Abrasion prior to preoxidation is an essential requirement for good coating adhesion on a chrome-iron substrate. The interface region for a coating on chrome-iron exhibits little interaction or microstructural change. -However the coating on mild steel exhibits extensive interaction, with a reaction zone extending into the coating. The marked difference between the two coated substrate types can be explained by the different substrate oxide formed, solubility of the substrate oxide in the coating and nucleating ability of the substrate oxide surface. Addition of adherence oxides (NiO, CoO) to the coating on mild steel was examined. The adherence oxides participate in complex reactions which result in the formation of metallic alloys adjacent the interface. Both adherence oxides promote wetting under conditions where wetting is not possible if they are absent. Nickel oxide is detremental to coating adhesion. This may be related to its ability to cause a rapid dissolution of iron oxide present at the interface.

A study of glass-ceramic coatings on metal substrates was carried out in order to understand how the coatings and substrates interact and how these interactions affect coating microstructures and properties. There are two systems involved. One is a lithium-silicate glass-ceramic coating on Ni/Cr/Co alloy and the other is a lithium-aluminosilicate glass-ceramic coatings (with some other optional compositions) on titanium metal. Simple techniques such as screen printing or the "droplet” method were used to coat the substrates with a layer of fine glass powder, and then a firing procedure followed to create a vitreous enamel layer on the metals. Heat treatment was usually applied to convert the vitreous coating into a highly crystallized, glass- ceramic coating since this generally results in superior properties. Because both the Ni/Cr/Co alloy and titanium metal are active metals, complicated interactions were observed at the coating/metal interface. In the Ni/Cr/Co case. Cr from the substrate tends to diffuse into the coating very rapidly at the firing temperature. The rapid diffusion of mainly Cr++ ions and subsequent change into Cr+++ ions results in saturation of Cr+++ ions in the glass coating. The second oxidation step proceeds more rapidly at the coating surface and LiCr(Si03)2 crystals start to precipitate on the surface of the coating. Mismatch of TEC, thermol expansion coefficient, between LiCr(Si03)2 and the coating causes severe disruption. In addition, some components in the coating, for instance, P2O5, react with Cr to form Cr^Pî. As a result, in the reaction zone, consumption of the intended nucleating agent P2O5 leads to a poorly crystallized structure affecting coating properties. In the titanium system, though long range diffusion across the interface was not observed, the major problem is the reactivity of titanium with coating components including Si( > 2. Direct reaction between titanium and silica gives TisSia as an interfacial layer and the gaseous O2 produced may disrupt the molten glass structure during firing. Other interactions such as Ti/P2Os can also proceed to give other damaging effects. In general, the coating on titanium after firing is usually very porous if these interactions are not prevented. Preoxidation of Ni/Cr/Co alloy created an adherent Cr203 layer on the alloy surface, and this layer is very stable in the coating glass due to its low diffusivity and solubility. The existence of this layer prevented direct contact of alloy and coating at the firing temperature, minimizing interfacial reactions and leading to the desired coating structure. From a chemical point of view, preoxidation of titanium metal can create a barrier of Ti02 between the coating and metal to hinder the formation of Ti5Si3. However, the poor bonding strength of this layer meant that it was ineffective in forming a transition layer between the metal and coating. Furthermore, the Ti02 can be readily dissolved by the coating glass during firing. Addition of an adherence oxide, CoO, was successful in 1) producing Ti02 in situ at the interfacial area and Co/Ti dendrites, both of which are necessary in maintaining chemical as well as mechanical bonding across the interface 2) diverting and hence minimizing the damaging direct reaction between Ti and SiC > 2 because the reaction between Ti and CoO always takes place prior to the reaction between Ti and Si02 thermodynamically. In the systems of glass-ceramic coatings for reactive metal substrates, various complications may occur. In this study, interactions of lithium-silicate/Ni/Cr/Co alloy and a wide range of glass-ceramic coatings/titanium have been studied. Detailed observation has been given together with explanation. Further work has also been suggested so that better understanding and application may generate from what has been observed in this project.

Solar modules made from thin - film crystalline - silicon layers on low - manufacturing cost substrates could decrease the cost of photovoltaic electricity if sufficiently high efficiencies could be reached. The main factors that affect the efficiency of solar modules are grain size and the preferred orientation of c-Si thin-film, which depends on the surface roughness of substrates and methods of depositing silicon film. In this work, spinel glass-ceramic produced from compositions of SiO2-Al2O3-ZnO-MgO-TiO2-ZrO2 system is used as a buffer layer between ceramic substrate and silicon thin - film. The glass - ceramic possess thermal expansion coefficients (CTE) of 30-52 × 10-7 K-1, which matches the CTE of both silicon and ceramic substrate. As the results, the surface roughness (Rq=0.8 nm) of glass-ceramic made by a two-stage heat treatment is smaller than that made by a single stage (Rq=3.1 nm). Besides, The glass transition temperature (Tg) of residual glass could be up to 1037 °C by a two – stage heat treatment. The crystallization of amorphous silicon films deposited by RF magnetron sputtering on buffer layers is studied by thermal annealing in the temperature range between 750 °C and 1200 °C for epitaxial growth. The epitaxy was carried out using a tube conventional furnace. And X-ray diffraction technique was used to determine the preferential orientation and grain size of the c-Si thin-film. The preferential orientation is <220> for all heat treatment temperature. And the grain size is increased by the increment of annealing temperature.

Abstract A ball-milled mixture of glass and alumina powders has been plasma sprayed to produce alumina-glass composite coatings. The coatings have the unique advantage of a melted ceramic secondary phase parallel to the surface in an aligned platelet composite structure. The alumina raises the hardness from 300HV for pure glass coatings to 900HV for a 60wt% alumina-glass composite coating. The scratch resistance increases by a factor of three and the wear resistance by a factor of five. The glass wears by the formation and intersection of cracks. The alumina wears by fine abrasion and supports most of the sliding load. The wear resistance reached a plateau at 40-50vol% alumina, which corresponds to the changeover from a glass to a ceramic matrix. Keywords: glass composite coatings, wear, thermal spraying

Abstract This paper discusses the development of a metal-coated glass tube that produces ozone more economically than traditional methods. It describes the principle of ozone generation, provides information on ozonizer tubes, and presents the criteria for selecting thermal spray powders. It examines the properties of several multilayer coatings consisting of an oxide ceramic top layer, an Al/Si interlayer, and a borosilicate glass substrate. It was found that the porosity and surface roughness of the oxide layer have a significant impact on the dielectric strength of the composite and the efficiency of the ozone-producing tube.

Abstract Thermal spraying offers the possibility of applying functional metal, ceramic or cermet coatings to components with different geometries and materials and significantly improving their thermal, mechanical, and chemical properties. The performance in operation as well as failure due to deformation, cracks, and delamination are mostly determined by the internal stress state within the coated components. This paper reviews coating developments on light metal and glass substrates, sprayed with different atmospheric plasma spray process spray parameters are reviewed. The results show that from the numerical and experimental residual stress analysis, the injection parameters can be influenced individually. This leads to optimized residual stress states in the coated components with regard to the expected operating loads. Paper includes a German-language abstract.

In this study, Mg/SiO2 and MgO/SiO2 multilayer coatings with bilayer thicknesses (Λ) 10, 20, 40, 100, 200 and 1000 nm were deposited on glass substrates using DC and reactive pulsed DC magnetron sputtering processes. The aim of these coatings is to control the initial degradation and provide mechanical strength to magnesium implant during handling and installation. The initial thickness calibrations and deposition rates optimization were conducted using stylus profilometer. After deposition of the multilayer coatings, the values of their bilayer thicknesses (Λ) were obtained from X-ray reflectometery. The mechanical properties, surface morphology and roughness of multilayer coatings were studied using nanoindentation, SEM and AFM respectively. The nanoindentation results showed higher hardness of MgO/SiO2 multilayer coatings compared to single layer Mg. The roughness analyses showed improved roughness for bilayer thicknesses (Λ) less than 20 nm. It was observed from the SEM images that SiO2 coatings has pores. By adding Mg and/or MgO in the form of multilayers improves the pores significantly. The Mg/SiO2 multilayer coatings showed controlled degradation rate when immersed in saline solution compared to the monolithic SiO2 coating. In conclusion, conditions for depositing Mg/SiO2 and MgO/SiO2 multilayer coatings has been optimized. Alternating brittle SiO2 ceramic layers with soft and ductile Mg layers significantly improved the hardness of the Mg coating. Hardness of multilayer coatings can be fine-tuned by modifying bilayer thicknesses. Significant improvement in the corrosion and mechanical properties of the multilayer coatings can be used to protect surface of magnesium implant material during handling, storage and installation.

Silicon carbide is currently used as a structural material for heat exchanger tubes and related applications because of its excellent thermal properties and oxidation resistance. Silicon carbide suffers corrosion degradation, however, in the aggressive furnace environments of industrial processes for aluminum remelting, advanced glass melting, and waste incineration. Adherent ceramic oxide coatings developed at Solar Turbines Incorporated with the support of the Gas Research Institute, have shown to afford corrosion protection to silicon carbide in a simulated aluminum remelt furnace environment as well as in laboratory type corrosion testing. The coatings are also protective to silicon carbide-based ceramic matrix composites.
