What are the surface treatment methods of high-speed diaphragm couplings?

Introduce:

High-speed diaphragm coupling is a mechanical device commonly used in high-speed transmission, its performance and life are closely related to surface treatment and other related factors. The following high-speed diaphragm coupling manufacturers will take us to discuss the surface treatment methods of high-speed diaphragm couplings.

The surface treatment method of high-speed diaphragm coupling:

Phosphating treatment

Phosphating is one of the commonly used surface treatment methods. It can form a very fine phosphating film on the surface of the diaphragm coupling, which can enhance the wear resistance, corrosion resistance and oxidation resistance of the surface. The treatment temperature of this treatment method is not high, the treatment time is not long, and it has almost no effect on the performance of the diaphragm coupling, so it is widely used.

Nitriding treatment

Nitriding treatment is a new technology that combines hardening treatment with surface treatment. This treatment method can form a high-hardness nitride film on the surface of the diaphragm coupling, thereby improving its wear resistance, corrosion resistance and oxidation resistance. At the same time, nitriding treatment can also improve the mechanical properties and dimensional stability of the diaphragm coupling, which is a better surface treatment method.

shot peening

Shot peening is a surface treatment method that sprays high-speed flowing particles onto the surface of the diaphragm coupling, thereby subjecting the surface to mechanical impact and friction. This treatment method can remove the scale and rust on the surface and increase the surface roughness, thereby improving the adhesion and compliance of the diaphragm coupling. At the same time, shot peening can also eliminate surface stress and improve surface quality, which is one of the more commonly used surface treatment methods.

Hardened

Hardening treatment is a surface treatment method that forms a high-hardness surface layer on the surface of the diaphragm coupling by means of heat treatment or chemical treatment. This treatment can improve the surface hardness, wear resistance and corrosion resistance of the diaphragm coupling, thereby protecting its surface from mechanical damage and chemical corrosion.

Anti-corrosion treatment

Anti-corrosion treatment is a surface treatment method for diaphragm couplings that are often exposed to harsh environments such as acid rain, sea water, and corrosive gases, and are prone to corrosion and aging. This treatment method can form a layer of anti-corrosion coating or base paint on the surface of the diaphragm coupling to protect the surface of the diaphragm coupling from corrosion and aging under high temperature, high humidity and other conditions.
