Introduction

Electro-galvanizing, also known as cold galvanizing in the industry, is the process of using electrolysis to form a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of the part.

Compared with other metals, zinc is relatively cheap and easy to be plated. It is a low-value anti-corrosion electroplating layer. Because zinc is not easy to change in dry air, and it can produce a basic form in a humid environment. Zinc carbonate film, this film can protect the internal parts from corrosion damage. Even if the zinc layer is damaged by some factors, the combination of zinc and steel over a period of time will form a micro-battery, and the steel matrix will become The cathode is protected.
