Q&A:

1. Q: What is zinc phosphating in surface treatment? 
A:Zinc phosphating is used to coat ferrous metals to provide rust-proofing and, when applied in conjunction with sealers, superior corrosion protection.  Zinc phosphate is a lighter coating than manganese phosphate and is used as an alternative coating for high wear parts.  Phosphate coatings are porous, making them ideal for surface preparation for additional coatings and painting. The zinc phosphate coating protects the underlying part surface from wear, corrosion, and rust. 

2.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.
