15 surface treatment processes for parts, this is probably the most complete summary I've ever seen, it's worth saving!

Overview of surface treatment technologies for parts

In the manufacturing industry, the surface treatment of parts is an extremely critical part of the process, which can enhance the corrosion resistance of the parts, but also to enhance their wear resistance, and improve the aesthetic properties, and thus improve product quality and service life. Like chrome plating, galvanising, nickel plating, spraying, anodising, electrophoretic coating, sandblasting, shotblasting, polishing, electroplating, chemical plating, hot dip plating, painting, powder coating, plastic spraying, these are the common 15 kinds of parts surface treatment process.

Chrome plating, which is mainly used in the surface treatment of metal products such as automobiles, motorbikes, bicycles, etc., is able to improve the corrosion resistance and aesthetics of these metal products. It has the advantage of high surface finish and good corrosion resistance, however, it has the disadvantage of high cost.

As far as the surface treatment of steel products is concerned, it is mainly used for galvanising to improve its corrosion resistance. It has the advantage of low cost and good corrosion resistance, however, it has the disadvantage of high surface roughness.

In the case of nickel plating, the surface treatment is mainly carried out in the electronic, mechanical and aeronautical fields in order to improve the corrosion resistance and hardness. The advantages are higher surface finish and hardness, but the disadvantages are higher cost.

Spray painting is a surface treatment for metals, plastics, wood and other materials, which enhances their aesthetics and abrasion resistance. It has the advantages of less capital investment and wider scope of application, but the disadvantage is that the coating thickness is not easy to control.

The surface of aluminium products after anodic oxidation treatment, mainly for aluminium alloy products, can enhance its corrosion resistance, but also can enhance the hardness. Advantage lies in the low cost, surface hardness is quite high, the disadvantage is that the colour is relatively single.

Electrophoretic coating is mainly used for surface treatment in automotive, electronics and home appliances to improve aesthetics and wear resistance. It has the advantages of uniform coating and low cost, but has the disadvantage that the coating thickness cannot be easily controlled.

Sandblasting, for metal, plastic materials, surface treatment to improve the roughness and adhesion, low cost and surface roughness can be controlled accordingly, but easy to generate more bubbles and burrs.

Shot peening is a method of surface treatment for metal products called shot peening, which improves the abrasion resistance and adhesion of metal products, with the advantage of lower cost. Moreover, it can make the surface hardness of metal products become higher, however, it has defects, easy to cause deformation and cracks of metal products.

In the surface treatment of materials such as metals and plastics, there is a treatment called polishing, which enhances the finish and aesthetics of these materials and has the distinctive feature of a high surface finish, but also has the disadvantage of being relatively costly.

Surface treatment of metal products, the main use of electroplating this way, the implementation of electroplating, can enhance the corrosion resistance of the metal products, but also can enhance the aesthetic degree. Electroplating has the advantage of lower cost, and its surface finish is relatively high, however, electroplating also has a disadvantage, that is, easy to produce bubbles and burrs.

Chemical plating is a surface treatment for metals, plastics, and other such materials that improves their corrosion resistance and enhances their aesthetics. It has the advantages of low cost and high surface finish, but the disadvantage is that the coating thickness is difficult to control.

Hot-dip plating is a method used for surface treatment of steel products to improve their corrosion resistance. It has advantages such as low cost and good corrosion resistance, but also has disadvantages such as high surface roughness.

Painting is a method of surface treatment for metals and plastics that enhances the aesthetic and wear-resistant properties of these materials. It has the advantage of being available in a wide range of colours and at a low cost, but the disadvantage is that the thickness of the coating cannot be easily controlled.

Surface treatment of metals, plastics and other materials will be used in powder coating, which can enhance the aesthetic degree of the material and wear resistance, has the advantages of low cost, uniform coating, but there are coating thickness is difficult to control the shortcomings.

Plastic spraying, which is mainly used for the surface treatment of plastic products, through this way to improve the aesthetics of plastic products, but also to enhance its wear resistance. It has the advantage of low cost, the coating is also more uniform, the disadvantage is that the coating thickness is not easy to get effective control.
