Abstract

Abstract : 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.
