Difference among nickel plating, galvanizing and chrome plating

- May 17, 2018 -

1: Nickel plating, galvanizing, and chrome plating are all used on metal surfaces.


2: The difference between nickel plating, galvanizing and chrome plating is:

a: Chromium plating mainly improves surface hardness, appearance, and rust resistance. Chromium plating has good chemical stability and does not work in alkalis, sulfides, nitric acid, and most organic acids, but it can dissolve in hydrohalic acid (such as hydrochloric acid) and hot sulfuric acid. Because chromium doesn't change color, it can maintain its reflection ability for a long time and superior to silver and nickel. The process is generally electroplating.

b: Nickel plating is mainly wear-resistant, corrosion-proof, and rust-proof. Generally, the thickness is relatively thin, and electroplating and chemical processes are divided into two categories.

c: Galvanizing is mainly aesthetically rust-proof. Zn is an active metal that reacts with acids and therefore has poor corrosion resistance and is the cheapest of the three.
