Texte intégralThis thesis manuscript relates to the study of process set up of an electrochemical surface treatment, called micro-arc oxidation (MAO), and applied to titanium and its alloys. The aim is to determine the influence of parameters such as nature of the substrate (alloying elements), chemistry of the electrolytic solution and electrical parameters, on the process. In-situ electrochemical behaviour of forming oxide layers is studied, as well as microstructural and chemical characteristics of formed coatings. Many methods mostly to characterize morphology (SEM, TEM imagery), chemistry (EDS, XRD, electron diffraction, EELS) and ex- situ electrochemical behaviour (OCP, polarizing, EIS) are used. Systematic study realised by voltamperometry and chronopotentiometry allowed to differentiate three anodizing stages (I/ conventional, II/ micro-arc, III/ of arcs), characterized by a particular electrochemical response of the metal/electrolyte interface, and which impacts obtained coating properties. Phenomenological models are proposed for each stage of anodizing and linked to MAO process parameters. Grade 2 commercially pure titanium and alloy Ti-6Al-4V (or TA6V) are comparatively studied; the influence of alloying elements (aluminium and vanadium) was discussed in relation with running of the process. Development of an electrolytic solution was carried out to obtain a thick and compact coating, mostly composed of aluminium titanate. Incorporation into the coating of elements from the electrolyte was discussed, and linked to in-situ electrochemical response; this study leaded to a proposed coating growth mechanism which involves elements from the substrate and from the electrolyte. Study of unipolar and bipolar pulsed regimes allowed discussing the effect of pause time and cathodic pulses on electrochemical response of the material and on coating properties. Study of the anodic / cathodic charge ratio showed it was an essential parameter to ensure growth of a thick, homogeneous and compact coating

Texte intégralAluminum-silicon alloys are widely used for the manufacture of parts with complex geometries for various applications (automotive / pistons / household appliances). Following the preparation of the samples by mechanical polishing, a porous oxide layer of fifteen microns is grown on the surface of the AS12 by anodization in acid or basic medium. After the anodization, a process known as sealing with long-chain carboxylic or phosphonic acids is carried out in order to increase the mechanical and anti-corrosion performances of the anodized samples. In order to evaluate the samples, several techniques were used: microscopy (SEM/ TEM) for morphological characterization, EDS analysis for composition, electrochemical (EIS) and non-electrochemical salt spray measurements for corrosion resistance evaluation and tribological tests for wear resistance characterization. Because of the cracks due to the silicon crossing the oxide layer, the samples anodized in sulfuric acid medium are characterized by a reduced corrosion resistance compared to those oxidized in alkaline medium where the silicon is completely oxidized on the surface. On the other hand, the nanometric size of the pores resulting from the sulfuric anodization offers a better resistance to wear. The sealing of the anodized samples in sulfuric medium leads to the plugging of the cracks generated by the metallic silicon and subsequently to the improvement of the corrosion resistance. However, due to the large size of the pores resulting from the anodization in alkaline medium, no significant improvement in the corrosion resistance is obtained. From the wear resistance point of view, the sealing does not bring any remarkable added value to the anodized samples

This research tries to improve corrosion resistance of LAZ1110, LAZ1110 +Be, LAZ1110 +Sc, LAZ1110 +Be +Sc magnesium alloys by means of micro-arc anodizing. In the experiment, the electrolytic solution is composed of 40gl-1 Na2SiO3, 100gl-1 NaOH, 20gl-1 NaPO2and 80gl-1(COOH)2.2H2O in distilled water. After the micro-arc anodizing treatment, it will discuss to various parameters. The results indicated that the anodic oxidation film has better corrosion performance under the pulse current condition. In four materials of LAZ1110, LAZ1110 +Be, LAZ1110 +Sc, LAZ1110 +Be +Sc magnesium alloys, LAZ1110 +Be have the worst of corrosion resistance, and LAZ1110 +Sc have the best of corrosion resistance, in the basic extrapolate, add the Be element have decrease the oxidation on the magnesium alloys surface, this phenomenon destroy the anodic oxidation film of LAZ1110 +Be during micro-arc anodizing treatment, add the Sc element have increase the effect of corrosion resistance. Temperature, frequency, time, current density, duty cycle and electrolytic concentration have an influence on micro-structure and corrosion performance of anodic films. In our research, it fixed current density and another parameter, and it used various of time parameter to find out the best operate condition, the results indicated that at 8min of operate condition of micro-arc anodizing treatment have the best of anodic oxidation film.

Taiwan’s bicycle industry has been renowned as a leading role around the world. However, the bicycle industry in Taiwan has to progress in the research and design ability in order to face the global competition. Among the bicycle parts, shock absorbers are the main components. They are made of aluminum alloys under the treatment of anodizing oxidation. Unfortunately, the surface characteristics of the treatment are unable to match the demands from bicycle industry. As a consequence, we prepare anodized composite and micro-arc composite films on Aluminum alloy by means of adding various solid lubricant particles (PTFE and MoS2) and surfactant in the electrolyte. The results indicate that the composite oxide films added with solid lubricant particles have lower average roughness and friction coefficient. In particular, the micro-arc composite film added with MoS2 has the best result of roughness, 1.10μm and friction coefficient, 0.496. Along the same lines, adding surfactant SDS and 1g/L PTFE added in the electrolyte for the micro-arc oxidation film is also effective to reduce the friction coefficient and wear loss of the films to 0.451 and 2.4mg/3000 rpm.
