Paper Title:
TiN Modified Layer on the 20CrNiMo Steel Surface by Needle–Shape Cathode Glow Plasma Discharging
  Abstract

The structure made of alloying and coating layers of TiN was achieved on the surface of 20CrNiMo steel by the needle-shape cathode glow discharging. It is aimed to reduce the friction coefficient of the 20CrNiMo and to improve the property of the wear-resistance. The morphology of TiN modified layer at cross section was observed by the scanning electron microscope (SEM). The friction and wear behavior of the TiN layer under dry sliding against GCr15 steel was evaluated on a MFT-4000 high speed to-and-fro wear test rig. The results showed that it was feasible to prepare TiN modified layer of 40μm thickness by the needle-shape cathode glow plasma discharging. It has been found that the TiN modified layer has excellent friction and wear-resistant behaviors. The friction coefficient of the 20CrNiMo substrate was about 0.324 under dry sliding, while the TiN modified layer experienced much abated friction coefficient to 0.169 under the same testing condition.
