Effects of deposition temperature and time on the surface characteristics of TiN-coated high-speed steel by arc ion plating

摘要

We present the effects of both deposition temperature and deposition time on the surface characteristics of TiN-coated high-speed steel(AISI M2) by arc ion plating. The microparticles, surface roughness, microhardness, coated layer thickness, adhesion strength, and atomic distribution of Ti, N, and Fe elements were measured for various deposition temperatures and times. The results demonstrated that a deposition temperature in the range of 400 to 500 °C had a slight influence on the surface characteristics, while a deposition time in the range of 10 to 180 min had a great influence on the microparticles, surface roughness, microhardness, coated thickness, atomic distribution of Ti, and adhesion strength.
