1. Q: What is zinc plating?
A: The zinc plating process offers several advantages to the metal. Zinc plated characteristics include an increase in corrosion resistance (comparable to cadmium) with an addition increase in resistance when chromates and sealers are used during the process. By zinc plating metal, it prolongs the life of the basis metal improves aesthetic value of the part and serves as a good paint base. Additionally, zinc plating services increase the lubricity and can be used for identification purposes when combined with chromates and dyes.
2.Q: What is black oxide coating?
A: Black oxide coating is a process which provides a conversion coating on iron which changes the surface of the material to a naturally occurring black iron oxide. Though the black oxide plating does provide some corrosion protection by itself it is necessary to put a protective oil on this finish to keep it from rusting.
