摘要

采用高效能超音速等离子喷涂系统

以实时监测喷涂粒子飞行状态对喷涂工艺进行过程控制

在45号钢基底表面上制备出孔隙率为1.6%左右、显微硬度（HV0.3）达到1 440的Cr2O3-16TiO2复相陶瓷涂层。经摩擦磨损试验

在油润滑条件下陶瓷涂层的摩擦因数随着载荷增加而增大

且涂层的磨损方式以接触疲劳磨损为主

表现出明显的表面划痕特征。

Abstract

The Cr2O3-16TiO2 coating was fabricated by high efficiency plasma spraying technology.The properties

such as micro-hardness

microstructure

were measured.Results show that the Cr2O3-16TiO2 coating is deposited with high density

and the micro-hardness of the coating reaches 1 440HV0.3and the porosity is about 1.6%

measured by image analysis（IMA）method.The SEM results show that the coating is composed of Cr2O3 and mainly TiO2 analysis by EDS and XRD.Under the condition of oil lubrication

the friction coefficient of the coating is increased with the increase of the loading

and the main wear mode is characterized by contact fatigue with apparent surface scratches.
