Paper Title:
Adhesion Strength between D.C. Plasma Nitrided Steels and CrN Films
  Abstract

The hard ceramic film made by PVD is used to increase the life and wear resistance of tools and dies. The adhesion strength between the ceramic film and surface of steels is important in ceramic coating of tools and dies. We investigated the adhesion strength between nitrided tool steel for dies SKD61 (JIS) and CrN film. The steel was plasma nitrided with 20 vol% N2 - H2 gas, and coated with CrN by means of PVD of HCD type. Thicknesses of the CrN films are 1 - 6 μm. Plasma nitriding time and thickness of the CrN films was examined to investigate adhesion strength between the CrN film and the steel. Maximum critical load value 55N at nitriding time 7,200 sec was obtained from the CrN coating on the surface of plasma nitrided SKD61
