What is the primary purpose of chromate conversion coating?
Chromate conversion coating provides a protective, corrosion-resistant layer on metals like aluminum and zinc. It also improves paint adhesion and maintains electrical conductivity, making it ideal for aerospace, electronics, and automotive applications.
How does chromate conversion differ from anodizing or plating?
Unlike anodizing or electroplating, chromate conversion does not add a thick external layer. Instead, it chemically transforms the surface itself into a thin, protective film, less than 1 µm, preserving dimensional accuracy while improving corrosion resistance.
Can chromate conversion coating be applied after CNC machining?
Yes. In fact, chromate conversion is most effective on freshly machined or cleaned metal surfaces. At XC Machining, parts are cleaned, deoxidized, and then conversion-coated to ensure optimal bonding, uniform finish, and protection without altering critical tolerances.
Are there environmentally safe alternatives to hexavalent chromate coatings?
Absolutely. Modern trivalent chromate and “chrome-free” conversion coatings offer comparable corrosion protection with reduced environmental and health risks. XC Machining uses REACH- and RoHS-compliant finishes to meet global sustainability standards.
How long does chromate conversion coating last?
The longevity of a chromate conversion coating depends on the environment and maintenance. In controlled conditions, it can protect aluminum parts for years. When combined with paints or sealants, it delivers exceptional long-term durability and resistance to corrosion.
