I'm not sure which type of plating you are using, possibily TiAlCN or other similar materials. If applied properly, the wear resistance is really good. Many PVD platings are actually developed for the tooling industry for wear resistance.
To get an idea of the wear resistance note the hardness values of the various types of PVD coatings ;
TiN - 2300 HV(microhardness)
TiCN - 3000
CrN - 1750
TiAlN - 3500
Here is one more hardness value I could dig out ;
CrC - 1850 HV(microhardness)
Is there anybody who can answer the following on PVD coatings ;
1) What is the corrosion resistance of the PVD coatings (TiN / CrN / CrC) ? Any data on Salt Spray resistance test as per ASTM B117 ?
2) Any data on following properties of PVD coatings
Bond Strength (ASTM C633)
Erosion Resistance (ASTM D968)
