Innovation from STS
To improve the characteristics of hardness, resistance to corrosion and smoothness of light alloys, we have developed a process that combines chemical nickel plating with PVD/PaCVD treatments. In this way it is possible to obtain a “gradient” effect for the hardness and enhance the characteristics of corrosion resistance and smoothness of the system.
