摘要
通过微弧氧化(MAO)法在电解液中加入 Na2S 和 Na3VO4,成功制备了 VSX/TiO2 复合层。通过 X 射线衍射、扫描电子显微镜和三维真彩显微镜对其结构、形貌和摩擦学性能进行了分析。结果表明,当 Na2S 浓度为 10-20 g/L 时,VSx/TiO2 复合层的厚度最大,摩擦系数和体积磨损最小。通过 MAO 原位制备的 VSx/TiO2 复合层可以改善 TC4 合金在高温下的摩擦学性能。
Microstructure and tribological properties of VSx / TiO2 composite layers in-situ prepared on TC4 alloy
The VSX/TiO2 composite layer was successfully prepared by adding Na2S and Na3VO4 into electrolytes through micro-arc oxidation (MAO) method. The structure, morphology and tribological properties were analyzed by X-ray diffraction, scanning electron microscopy and 3D true color microscopy. The results show that when the concentration of Na2S is 10-20 g/L, the thickness of VSx/TiO2 composite layer is the thickest, and the friction coefficient and volume wear are the lowest. The VSx/TiO2 composite layer in-situ prepared by MAO can improve the tribological properties of TC4 alloy at high temperature.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
