What are the surface treatment methods of metal from ycbing's blog

Our commonly used metal materials are iron, aluminum, copper, etc. These metals have active chemical properties. In order to make these metal materials more durable and more beautiful, their surfaces are usually treated. What are the  Surface Finishing  methods of metal

1. Apply anti-rust paint:

Antirust paint is a kind of paint that can protect metal surface from chemical or electrochemical corrosion such as atmosphere and sea water. It is mainly divided into two categories: physical antirust paint and chemical antirust paint.

Features: bright color and strong coating adhesion, but most anti-rust paints are expensive, have poor durability, poor anti-rust effect, and are easy to fall off after a long time.

2. Electroplating process:

Electroplating refers to a surface treatment method in which the base metal to be plated is used as a cathode in a salt solution containing pre-plated metal, and the cations of the pre-plated metal in the plating solution are deposited on the surface of the metal to be plated. Base metals form coatings by electrolysis.

Features: high strength, strong wear resistance, strong heat dissipation, strong corrosion resistance.
