摘要

采用低压电弧喷涂方法制备了Ti涂层

对其成分和组织进行了分析

并研究了喷涂工艺对涂层中杂质含量及对喷涂粒子形态的影响。结果表明

在Ar气保护条件下

防止涂层氧化和氮化仍然有一定的困难

需要采用低真空度保护才可能制备出致密的涂层。另外

分析了变形+再结晶处理工艺对Ti涂层中喷涂粒子界面的作用

并对涂层的耐腐蚀性能进行了试验。

Abstract

Composition and microstructure of Ti coating prepared by low pressure arc spraying method were investigated

and effects of spraying parameters on impurity content in the coating prepared and morphology of sprayed particle were analyzed. The results reveal that it is still difficult to prevent the coating from oxidation and nitridation in Ar atmosphere

so it is necessary for the preparation of a dense coating in low pressure. In addition

the role of deformation plus recrystallization treatment in the boundary among sprayed particles was described. Meanwhile

corrosion resistance of the coating was examined.
