Surface Treatment

Parts of the 15 kinds of surface treatment process, this may be the most complete summary I have seen, it is 

worth saving!

Parts surface treatment process is an indispensable part of the manufacturing industry, it can improve the 

corrosion resistance, wear resistance, aesthetics and other properties of the parts, thereby improving the quality 

and service life of the product. The 15 common parts surface treatment processes include chrome plating, 

galvanizing, nickel plating, spraying, anodizing, electrophoretic coating, sandblasting, shotblasting, polishing, 

electroplating, chemical plating, hot dip plating, painting, powder coating, plastic spraying.

Chrome plating: It is mainly used for the surface treatment of metal products such as automobiles, motorcycles, 

bicycles, etc. to improve their corrosion resistance and aesthetics. The advantages are high surface finish, good 

corrosion resistance, the disadvantage is higher cost.

Galvanized: mainly used for surface treatment of steel products to improve its corrosion resistance. Advantage 

is low cost, good corrosion resistance, the disadvantage is that the surface roughness is higher.

Nickel plating: mainly used for surface treatment in electronics, machinery, aviation and other fields to improve 

its corrosion resistance and hardness. The advantage is high surface finish and hardness, the disadvantage is 

higher cost.

Spraying: mainly used for the surface treatment of metal, plastic, wood and other materials, which can improve 

its aesthetics and wear resistance. The advantage is low cost, wide range of application, the disadvantage is that 

the coating thickness is not easy to control.

Anodic oxidation: mainly used for surface treatment of aluminum alloy products, can improve its corrosion 

resistance and hardness. The advantages are low cost, high surface hardness, and single color.

Electrophoretic coating: mainly used in the surface treatment of automobile, electronics, home appliances and 

other fields, which can improve its aesthetics and wear resistance. The advantages are uniform coating, low cost, 

the disadvantage is that the coating thickness is not easy to control.

Sandblasting: mainly used for surface treatment of metal, plastic and other materials, can improve its roughness 

and adhesion. The advantages are low cost, controllable surface roughness, the disadvantage is easy to produce 

bubbles and burrs.

Shot Peening: mainly used for surface treatment of metal products, can improve its wear resistance and adhesion.

The advantages are low cost, high surface hardness, the disadvantage is easy to produce deformation and cracks.

Polishing: mainly used for surface treatment of metal, plastic and other materials, can improve its finish and 

aesthetics. The advantage is the high surface finish, the disadvantage is the higher cost.

Electroplating: mainly used for surface treatment of metal products, can improve its corrosion resistance and 

aesthetics. The advantage is low cost, high surface finish, the disadvantage is easy to produce bubbles and 

burrs.

Chemical plating: mainly used for surface treatment of metal, plastic and other materials, can improve its 

corrosion resistance and aesthetics. Advantage is low cost, high surface finish, the disadvantage is that the 

coating thickness is not easy to control.

Hot dip plating: mainly used for surface treatment of steel products, can improve its corrosion resistance. The 

advantages are low cost, good corrosion resistance, the disadvantage is that the surface roughness is higher.

Spray paint: mainly used for surface treatment of metal, plastic and other materials, can improve its beauty and 

wear resistance. Advantage is rich in color, low cost, the disadvantage is that the coating thickness is not easy to 

control.

Powder Coating: Mainly used for surface treatment of metal, plastic and other materials, which can improve its 

aesthetics and wear resistance. The advantages are low cost, uniform coating, the disadvantage is that the 

coating thickness is not easy to control.

Plastic spraying: It is mainly used for surface treatment of plastic products, which can improve its aesthetics and 

wear resistance. The advantages are low cost, uniform coating, the disadvantage is that the coating thickness is 

not easy to control.
