Abstract

Y2O3 coatings were fabricated on using atmospheric plasma spraying (APS). The effects of different process parameters on the microstructure and properties of the coating were analyzed. The results show that the overall morphology of Y2O3 coatings are smooth at high spraying power, low spraying distance and low primary gas flow rate, which is consistent with the change trend of porosity and hardness. The minimum porosity of coating is about 1.4%. The roughness of coatings isn’t sensitive to changes in parameters. Y2O3 coatings have excellent corrosion resistance. The smaller the porosity of Y2O3 coating, the better the corrosion resistance.

大气等离子喷涂工艺参数对氧化钇涂层微观结构和性能的影响

使用大气等离子喷涂（APS）制造了 Y2O3 涂层。分析了不同工艺参数对涂层微观结构和性能的影响。结果表明，在高喷涂功率、低喷涂距离和低一次气体流速条件下，Y2O3 涂层的整体形貌光滑，这与孔隙率和硬度的变化趋势一致。涂层的最小孔隙率约为 1.4%。涂层的粗糙度对参数变化不敏感。Y2O3 涂层具有优异的耐腐蚀性。Y2O3 涂层的孔隙率越小，耐腐蚀性越好。

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.
