Chrome plating on tungsten alloy surfaces can greatly enhance corrosion resistance. This is a common surface engineering technique used to improve durability and decorative appearance.
1. Basic Principle of Chrome Plating
Chrome plating—primarily referring to hard chrome plating—is an electrochemical process that deposits a dense chromium (Cr) layer on the surface of a metal. This chromium layer features:
- High hardness (HV800~HV1000)
- Excellent wear resistance and low friction coefficient
-
Good chemical stability and oxidation resistance
