Abstract:
Metal-ceramic composite applications range from electronic devices such as electronic packaging, thin-film technology in microwave circuitry, and magnetic storage media to catalyst supports, protective coatings, and high-temperature structural components. These applications rely heavily on the ability to engineer the mechanical and electronic properties of metal-ceramic interfaces. To understand fundamental aspects of these interfaces, a variety of experimental and theoretical studies on “model systems” have been performed, correlating macroscopic material behavior and microscopic characteristics. The results serve as a guide to more complex systems, with a closer relationship to technological applications.

Abstract:
Metal-ceramic systems play very important role in the prosthetic dentistry. The most widely used metallic alloys are the Ni-Cr, Co-Cr, Au-based alloys and Ti. The bonding strength between the metal base and the ceramic covering layer can be very different in different systems and is strongly affected by the firing conditions as well. For the further improvement of the bonding properties the detailed knowledge of the microstructure of the metal–ceramic interlayer is essential. In this work our results, obtained by scanning and transmission electron microscopy on systems of commercial alloys and corresponding porcelains will be reviewed.

Abstract:
Fracture and deformation in model brittle-outerlayer/metal-core/polymer-substrate trilayer systems in concentrated loading are studied. Model systems for experimental study are fabricated from glass microscope slides glued with epoxy adhesive onto steel and aluminum sheets, and the resulting laminates glued onto polycarbonate substrate bases. Critical loads to initiate two basic fracture modes in the glass layers—cone cracks at the top surfaces and radial cracks at the undersurfaces—are measured as a function of metal thickness byin situobservation through the glass side walls. Finite element modeling (FEM) is used to quantify these competing fracture modes. The more damaging radial fracture mode is attributed to flexure of the glass layers on soft underlayers. Although much of this flexure can be eliminated by removing the soft adhesive interlayer between glass and metal, yield in the metal limits the potential increases in critical load for radial cracking. Trilayer systems consisting of porcelain fused to Co-, Pd- and Au-alloy core support layers relevant to dental crowns are then analyzed by FEM. The hardness (especially) and elastic modulus of the metal are identified as the primary controlling material parameters, with modulus and strength of the brittle layer as supplemental parameters. Guidelines for improving metal-based crownlike layer structures are thereby developed via optimization of metal properties and relative layer thicknesses.

Abstract:
Background/Aim. Metal-ceramic bond strength and alloys' elastic modulus clearly determine the potential of alloy application, because the ceramic integrity during mastication depends on these two characteristics. The aim of this study was to evaluate metal-ceramic bond strength and elastic modulus of cobalt-chromium alloys in making porcelainfused- to-metal restorations, regarding the application of the most frequent nickel-chromium alloy. Methods. The research was performed as an experimental study. Six metalceramic samples were made from nickel-chromium alloy (Wiron 99) and cobalt-chromium alloy (Wirobond C), according to the manufactures manuals and instructions from ISO 9693: 1996. Three-point bending test was performed up to the ceramic fracture. The fracture load was measured on an universal testing machine (Zwick, type 1464), with cross-head speed of 0,05mm/min. Results. The results of this study confirmed the significant differences between the metal-ceramic bond strength (p < 0.01) and elastic modulus (p < 0.001) of nickel-chromium and cobalt-chromium alloys, where cobalt-chromium alloys showed higher values for both tested parameters. Conclusion. Cobalt-chromium metal-ceramic alloys can successfully replace nickel-chromium alloys, especially for fabrication of long-span metal-ceramic bridges due to the great flexural strength.

The partial fixed prosthodontics restoration is used to rehabilitate form and function of partial or total compromised teeth, having to remain permanently joined to remainder tooth. The most useful material on prosthodontics is the feldspar porcelain, commercialized as aluminosilicate powders. Dental porcelains are presented with limited mechanical properties to rehabilitate extensive spaces. The association with Ni-Cr metallic systems (metal-ceramic system) allows that the metallic substructure compensates the fragile porcelain nature, preserving the thermal insulation and aesthetics desirable, as well as reducing the possibility of cracking during matication efforts. Cohesive flaws by low mechanical strength connect the metallic substructure to the oral environment, characterized by a electrolytic solution (saliva), by aggressive temperature, pH cyclic changes and mechanical requests. This process results on ionic liberation that could promote allergic or inflammatory responses, and/or clinical degradation of ceramometal system. The aim of this study was to evaluate the presence of an intermediate titanium layer on the microscopic fracture behavior of porcelains on ceramometal systems. Plasma deposition of titanium films result in regular passivating oxide layers which act as barriers to protect the metallic substrate against the hazardous effects of corrosive saliva. Tribocorrosion tests were performed to simulate the oral environment and mechanical stress, making it possible the early detection of crack formation and growth on metal-ceramic systems, which estimate the adherence between the compounds of this system. Plain samples consisting of dental feldspar porcelain deposited either onto metallic substrates or titanium films were fired and characterized by scanning electron microscopy. The result showed that the titanium film improved the adherence of the system compared to conventional metal-ceramic interfaces, thus holding crack propagation
A pr?tese parcial fixa ? empregada na reabilita??o da forma e fun??o de dentes parcial ou totalmente comprometidos, devendo permanecer unida permanentemente aos remanescentes dent?rios. O material mais utilizado na confec??o de pr?teses odontol?gicas ? a porcelana feldsp?tica, disponibilizada sob a forma de p? de aluminossilicatos. As porcelanas odontol?gicas apresentam-se com propriedades mec?nicas limitadas para a reabilita??o em monobloco de espa?os ed?ntulos extensos. A associa??o com sistemas met?licos de n?quel-cromo (sistema metalocer?mico) permite que a infra-estrutura met?lica compense a natureza fr?gil da porcelana, preservando-se a isola??o t?rmica e est?tica desej?veis, bem como reduzindo a possibilidade do desenvolvimento de trincas durante os esfor?os mastigat?rios. Falhas coesivas por baixa resist?ncia mec?nica da porcelana, comunicam a estrutura met?lica com o ambiente oral, caracterizado pela presen?a de uma solu??o eletrol?tica (saliva), pela agressividade das varia??es c?clicas de temperatura, pH e das solicita??es mec?nicas. Este processo resulta na libera??o de ?ons met?licos que podem desencadear respostas al?rgicas ou inflamat?rias, e /ou na degrada??o cl?nica precoce do sistema metalocer?mico. Este trabalho teve por objetivo avaliar o efeito da presen?a de uma camada intermedi?ria de tit?nio sobre o comportamento fratogr?fico, microsc?pico de porcelanas em sistemas metalocer?micos. A aplica??o por plasma de um filme fino de tit?nio, gera uma camada ?xida passivante regular que tende a proteger o substrato met?lico contra os efeitos corrosivos da saliva. Ensaios tribocorrosivos foram realizados para simular o ambiente oral, detectando precocemente a forma??o de trincas no sistema metalocer?mico, o que qualifica a ader?ncia entre os componentes do referido sistema. Foram produzidas amostras planas nas quais suspens?es de porcelana feldsp?tica odontol?gica foram depositadas e queimadas sobre substratos met?licos modificados por filme fino de tit?nio, comparando-as com o sistema metalocer?mico convencional. O sistema de teste apresentou melhores resultados, caracterizando-se pelo menor n?mero de tra?os de fratura superficial adjacentes ? ?rea de ensaio

No presente estudo avaliou-se a radiopacidade de restaurações cerâmicas livres de metal de forma objetiva, subjetiva e por meio de MEV/EDS. Foram utilizadas as cerâmicas: Noritake EX-3 (Noritake), VM13 (Vita), IPS Empress II (Ivoclar Vivadent), IPS E.max ZirPress (Ivoclar Vivadent) e PM9 (Vita). Para a avaliação objetiva foram confeccionados cinco corpos de prova nas espessuras de 1, 2, 3 e 4 mm, que foram radiografados juntamente com uma escala de densidade e uma secção dental, utilizando-se sistema digital direto. As imagens radiográficas foram submetidas à leitura de densidade óptica. Para a avaliação subjetiva foram confeccionados phantoms, simulando a parte posterior das arcadas dentárias, no qual dois dentes de cada phantom foram submetidos a preparos inlay, restaurados com as cerâmicas estudadas, e radiografados pela técnica interproximal. Essas radiografias foram avaliadas por três grupos de examinadores: cirurgiões-dentistas, radiologistas e protesistas. Para a análise dos elementos químicos que dão características de radiopacidade aos materiais, foi realizada avaliação pelo MEV/EDS. Os resultados da avaliação objetiva indicaram diferenças significativas entre as radiopacidades das cerâmicas estudadas. Para 1 e 2 mm de espessuras todas as cerâmicas apresentaram radiopacidade superior a da dentina e inferior a do esmalte. A cerâmica Noritake EX3 apresentou maior radiopacidade em todas as espessuras. Não se puderam constatar, nas avaliações simulando condições clínicas, as diferenças de radiopacidades observadas na avaliação objetiva. O grupo dos cirurgiões-dentistas apresentou a menor acurácia diagnóstica quando comparados aos grupos de especialistas, sendo que os radiologistas apresentaram a maior acurácia diagnóstica para cerâmica (0,57). Independente do grupo de avaliadores, não foi possível a distinção radiográfica entre cerâmicas livre de metal e compósitos. O resultado da avaliação dos materiais pelo MEV/EDS indicou como possíveis elementos radiopacificadores: bário para as cerâmicas Noritake EX-3 (2,19%), VM13 (1,04%), PM9 (0,70%) e IPS Empress II (0,70%); e zinco (4,50%) e cério (1,45%) para a cerâmica IPS E.max ZirPress.
The aim of this study to evaluate the radiopacity of metal-free ceramic restorations in an objective, subjective and by SEM and EDS. Ceramics were used: Noritake EX-3 (Noritake), VM13 (Vita), IPS Empress II (Ivoclar Vivadent), IPS e.max ZirPress (Ivoclar Vivadent) and PM9 (Vita). For the objective evaluation were prepared five specimens with thickness of 1, 2, 3 and 4 mm, which were radiographed with a aluminum step and a dental section, using direct digital system. The radiographic images were submitted to the reading of optical density. For subjective evaluation were fabricated phantoms, simulating the back of the dental arches, in which two teeth of each phantom received an inlay preparation, were restored with the studied ceramics, and were x-rayed by the interproximal technique. These radiographs were evaluated by three groups of examiners, dentists, radiologists, and prosthetists. To analyze the chemical elements that provide radiopacity characteristics of the materials, evaluation was performed by SEM and EDS. The results of objective evaluation indicated significant differences between the radiopacity of the studied ceramics. For 1 and 2 mm in thickness and the ceramics were all higher radiopacity dentin and enamel below. Ceramics Noritake EX3 showed higher radiopacity in all thicknesses. There was evident on the evaluations simulating clinical conditions, the differences observed in the radiopacity of objective evaluation. The group of dentists had a lower diagnostic accuracy when compared to groups of specialists, and radiologists had the highest diagnostic accuracy for ceramics (0.57). Independent group of evaluators was not possible to distinguish between X-ray and metal-free ceramic composites. The result of evaluation of materials by SEM and EDS indicated as possible elements radiopacifiers barium to ceramic Noritake EX-3 (2.19%), VM13 (1.04%), PM9 (0.70%) and IPS Empress II (0.70%) and zinc (4.50%) and cerium (1.45%) for the ceramic IPS E.max ZirPress.

Abstract:
Advanced, coal- and biomass-based gas turbine power generation technologies (IGCC, PFBC, PCFBC, HIPPS) are currently under development and demonstration. Efforts at the Siemens Westinghouse Power Corporation (SWPC) have been focused on the development and commercialization of hot gas filter systems as an enabling technology for power generation. As part of the commercialization effort, SWPC has been actively involved in the development of advanced filter materials and component configuration, has participated in numerous surveillance programs characterizing the material properties and microstructure of field tested filter elements, and has undertaken an extended accelerated filter life testing program. This paper reviews SWPC’s material and component assessment efforts, identifying the performance, stability, and life of porous oxide- and nonoxide-based ceramic, as well as metal and intermetallic filters used in advanced, high temperature, coal combustion systems.

Abstract:
Brazed joints were made between silicon nitride and Ni-based and Fe-based super alloys. Room temperature shear (torsion) strengths ranged from 75–242 MPa for Si3N4-to-Incoloy 909 joints and from 30–127 MPa for the Si3N4-to-Inconel 718 joints. At 500 °C the joint strength was 120 MPa while at 650°C and 950°C the joints strengths were less than 20 MPa. These low strengths at 650°C and 950°C were attributed to a reduction in the shrink-fit and to low braze strength at these high temperatures. Finite element analysis (FEA) and a probabilistic failure theory (CARES) were used to predict the joint strengths. The predicted joint strengths agreed well with measured joint strengths in torsional loading at 20°C. Torsion tests were also performed at 650°C. Aspects of the material systems, residual stresses, mechanical behavior, and strength predictions are presented. Two new braze alloys based on the Au-Ni-Cr-Fe system were used to overcome the poor high temperature strength. Joints made with these brazes had good strength (85 MPa and 35 N-m) at 650°C.

Abstract:
A new probabilistic failure criterion was developed for the design of high-temperature ceramic-to-metal joints. The essential feature of the theory is the inclusion of the energy dissipated during plastic deformation of the adjacent braze layer in the joint. A large number of bi-material interface fracture simulations were performed for different crack positions and orientations near the bimaterial interface to determine the effect on stresses in the ceramic near the interface. The effective stress values were then ported to a probabilistic failure analysis code, which permitted simple inclusion of the new failure criterion. Brazed joints were made and failure tested in torsion to verify the failure criterion. Results show that the new failure criterion more closely approximates the failure of the ceramic-to-metal joints over the entire range of ultimate loads, an is a significant improvement in the failures criteria previously used for this type of joint design. Aspects of the failure criterion, material systems, residual stresses, mechanical behavior, and strength predictions will be presented.

Abstract:
The paper provides a synopsis of the research activities currently pursued at the Technical University Berlin, Hahn-Meitner-Institut Berlin and Honeywell Engines & Systems with respect to ceramic/metal joining concept for small ceramic high temperature gas turbine rotors. The objective was to design an interference fit type joint that can be cost effectively produced and reliably transmit torque at elevated temperatures (up to 800°C). Experimental and numerical investigations have been carried out to examine two slightly different designs which both utilize the same basic principle of a shrink fit connection that is able to compensate the thermal expansion mismatch between ceramic and metal and therefore is capable of keeping the contact pressure at the ceramic/metal interface nearly constant over a wide operating temperature range. The joints have been tested under torsional load at isothermal conditions in order to determine the static coefficient of friction and the torque carrying capability, as well as to optimize the joint geometry. The stress distribution inside the joint has been determined by FEA and subsequently evaluated by measuring the residual stress state of the joint in the ceramic by neutron diffraction.

Abstract:
Metal-ceramic composites are being increasingly explored in an effort to find new materials for use in extreme environments. Via functional grading of of the volume fraction of the constituant phases and other techniques, the material can be optimized to incorporate the mechanical properties of the metal phase with the thermal properties of the ceramic phase. To get further benefit of the metal phase, a new area being investigated is the incorporation of Shape Memory Alloys (SMAs). In order to predict the phase transformation features of an SMA embedded in a stiff ceramic matrix, a micromechanical approach is developed to find the effective phase diagram of the ceramic-SMA composite. From this analysis, other composite characteristics such as stress in each phase and the evolution of tranformation strain in the SMA can be determined in order to improve the design of such new composite materials.
