The objective of this work is to study the tribological behavior of the contacting surfaces of SKD11 grade hardened cold work tool\nsteel against grade SUS304BA austenitic stainless steel. DLC, CrN, TiN, and TiCN films were coated on the surface of the tool\nmaterial to test the tribological performance. Simulation testing with a pin-on-disk was used in this study. The study was done\nunder dry conditions with sliding velocities at 50, 100, and 150 mm/s and contact pressures of 807, 1095, and 1280MPa. The\nresults show that the main problem is the adhesion of the workpiece material on the tool surface. The severity of the adhesion from\nthe workpiece material is proportional to the sliding velocity and the contact pressure between the contacting surfaces. The\ncoefficient of friction between the contacting surfaces has a positive relationship with the adhesion occurring on the tool surface.\nThe hardness of the film coating is useful for preventing wear of the tool material, especially under high pressure between the\ncontacting surfaces. However, it does not prevent the adhesion of workpiece material of low sliding velocity and low contact\npressure conditions. Noncoated SKD11 tool steel has better effectiveness of adhesion performance than CrN, TiN, and TiCN\nfilm coatings.
