Do you know some basic knowledge about plasma spraying?

Below will be a brief introduction to the advantages and characteristics of plasma spraying. Plasma spraying uses rigid non transfer plasma arc as the heat source. In the mechanical industry, due to complex working conditions, bearings in mechanical equipment often wear out, seriously affecting the service life of the equipment. By using plasma spraying technology, anti-corrosion coatings can be prepared on the surface of bearings, which not only does not affect the strength of the bearings, but also provides good protection for the bearings.

Plasma spraying uses plasma arc as a heat source to heat the material to a molten or semi molten state, and then sprays it at high speed onto the surface of the workpiece to form a sturdy surface. Plasma spraying is a material surface strengthening technology with characteristics such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, surface strengthening, and surface modification.

Equal particle spraying uses plasma arc, which is a compression arc. Compared with free arc, the arc column is delicate, the current density is high, the degree of gas electrification is high, and it has the characteristics of high temperature, energy concentration, and arc stability. Plasma spraying technology is a multi-purpose precision spraying method developed after flame spraying.

1. Ultra high temperature characteristics, convenient for spraying high melting point materials;

2. Fast particle spraying speed, dense coating, and high bonding strength; Due to the use of inert gas, the sprayed material is not easily oxidized.
