摘要:

采用先驱体转化陶瓷法(PDC 法)制备含 ZnO 晶须的 Ti-Si 复合陶瓷涂层,将 ZnO 晶须添加到激光裂解 Ti-Si 复合陶瓷涂的先驱体中,增强 Ti-Si 复合陶瓷涂层的防腐蚀性能和减摩耐磨性能。通过扫描电子显微镜( SEM)、X 射线衍射仪(XRD)、往复式摩擦磨损测试仪、电化学工作站等手段,分析含不同质量分数 ZnO 晶须的 Ti-Si 复合陶瓷涂层的元素组成及存在形式、表面形貌、摩擦磨损性能以及防腐蚀性能。添加 ZnO 晶须对 Ti-Si 复合陶瓷涂层的组成和化学价态没有影响,但添加 ZnO 晶须对 Ti-Si 复合陶瓷涂层的防腐性能有改善,添加 ZnO 晶须对 Ti-Si 复合陶瓷涂层的减摩性能有改善,在较高载荷下添加 ZnO 晶须可以降低 Ti-Si 复合陶瓷涂层的摩擦因数,添加 ZnO 晶须质量分数为 10%所得的 Ti-Si 复合陶瓷涂,载荷为 5 N 和 7 N 时摩擦因数均比 45 钢低 52%。添加不同质量分数 ZnO 晶须对复合陶瓷涂层表面表面形貌有很大影响,同时可以改善 Ti-Si 复合陶瓷涂层摩擦磨损性能以及防腐蚀性能。

Abstract:

Ti-Si composite ceramic coating containing ZnO whiskers was prepared by precursor conversion ceramic method ( PDC). ZnO whiskers were added to the precursor of laser pyrolysis Ti-Si composite ceramic coating to enhance the corrosion the corrosion re- sistance, friction and wear resistance of Ti-Si composite ceramic coating. By means of scanning electron microsope ( SEM), X-ray powder diffraction (XRD), reciprocating friction and wear tester, electrochemical workstation, and etc. The addition of ZnO whiskers had no effect on composition and chemical speciation of Ti-Si composite ceramic coating. But the addition of ZnO whiskers can improve Ti-Si composite ceramic coating’s anti-corrosion and anti-friction performance. Moreover, adding ZnO whiskers under high load can re- duce the friction coefficient of Ti-Si composite ceramic coating. The Ti-Si composite ceramic coating obtained by adding ZnO whisker of 10% mass fraction under loads of 5 N and 7 N has 52% lower friction coefficient than steel -45. The addition of different mass frac- tions of ZnO whiskers has a great effect on the surface morphology of composite ceramic coatings, and can improve the anti-corrosion and anti-friction performance of Ti-Si composite ceramic coating.
