Purpose

The purpose of this paper is to prepare Ti(C,N) coatings on TA15 treated and not treated by shot peening using double glow plasma alloying technique. The effect of shot peening on the wear behavior of Ti(C,N) coatings is discussed.

Design/methodology/approach

The Ti(C,N) coatings were prepared by double glow plasma alloying technique on two different TA15 substrate; one is shot peened and the other is not.

Findings

Ti(C,N) coating on SP-treated TA15 was thicker and denser, and the grain size was smaller compared with that on original TA15. Compared with the Ti(C,N) coating on original TA15, the wear resistance of that on SP-treated TA15 is improved. Ti(C,N) coating on SP-treated TA15 showed higher nanohardness and bearing capacity than that on original TA15.

Originality/value

For double glow plasma alloying technique, surface quality, surface activity and other factors will have influence on the thickness and density of the coating. The wear mechanisms of Ti(C,N) coating on original TA15 are serious abrasive wear and oxidation wear. However, the wear mechanism of Ti(C,N) coating on SP-treated TA15 is slightly oxidation wear.

喷丸处理对双辉等离子碳氮共渗TA15合金Ti（C，N）涂层磨损行为的影响

目的

本文的目的是在TA15上使用双辉等离子合金化技术在喷丸处理和未喷丸处理上制备Ti（C，N）涂层。讨论了喷丸处理对Ti（C，N）涂层磨损行为的影响。

设计/方法/方法

采用双辉等离子合金化技术在两种不同的TA15基体上制备了Ti（C，N）涂层。一种是喷丸，另一种不是。

发现

经SP处理的TA15上的Ti（C，N）涂层较厚且致密，与原始TA15相比，其晶粒尺寸较小。与原始TA15上的Ti（C，N）涂层相比，经SP处理的TA15上的Ti（C，N）涂层具有更高的耐磨性。经SP处理的TA15上的Ti（C，N）涂层显示出比原始TA15更高的纳米硬度和承载能力。

创意/价值

对于双辉等离子合金化技术，表面质量，表面活性和其他因素将影响涂层的厚度和密度。原始TA15上的Ti（C，N）涂层的磨损机理是严重的磨料磨损和氧化磨损。但是，经SP处理的TA15上的Ti（C，N）涂层的磨损机理是轻微的氧化磨损。
