hardness is an important performance index to measure

1. High hardness – hardness is an important performance index to measure the degree of compressive deformation of product materials. Let's look at a set of data: HV - Vickers Hardness
Evaporation Vacuum Coating Machine Manufacturers

A nickel layer thickness 0.005 hardness - about 180HV
B hardness of electroless nickel plating containing phosphorus - about 300HV
C Hardness of aluminum substrate -- about 100HV
Hardness of anodized film - about 300HV
Hardness of hard anodized film - about 500HV
D Hardness of wet hard chromium electroplating -- about 800HV
E. Hardness of the coating produced by PVD process -- about 1600HV
