What are the advantages of plasma spraying?

Plasma spray gun is an important component of atmospheric pressure plasma jet. The surface of the processed material is generally sprayed through a plasma nozzle within a range of 5-30mm. The plasma spray gun generates a certain temperature during operation. When installing the plasma spray gun, stars can be combined with metal brackets to facilitate heat dissipation. The processed material is usually passed through the opening of the plasma spray gun in the form of assembly line motion.

When working, items handling materials should not be left idle in the plasma jet area for a long time to avoid being damaged or burned by high temperatures! Be careful not to touch or burn your hands during use! Plasma spray gun and its internal cable voltage are too high, be careful to prevent accidental damage and electric shock danger! Before opening the chassis for cleaning, the power must be cut off first. When there are ceramic materials inside the plasma spray gun, avoid being damaged by impact during movement, installation, and use. After prolonged use, the plasma gun will accumulate a certain amount of dirt in the body, requiring regular maintenance, cleaning, and timely replacement of consumables.

At present, plasma spraying is an increasingly popular spraying method that not only greatly reduces costs, but also helps customers improve completion efficiency and shorten construction periods.

1. Simple operation, low equipment maintenance cost, and good adjustment performance

2. The working gas of plasma is inert gas, which can better protect the substrate and powder from oxidation and reduce impurities in the coating.

3. The flight speed of plasma sprayed particles can reach 200-500m/s, which can make the sprayed surface smoother and more delicate.

4. The temperature of the plasma flame is very high, and its energy is highly concentrated on all high hardness and high melting point powders, making it a widely used spraying material for preparing various coatings.

5. Plasma equipment includes: spray gun, power supply, powder feeder, heat exchanger, gas supply system, and control framework.

6. Plasma spraying includes gas plasma spraying, protective atmosphere plasma spraying, vacuum plasma spraying, and water stable plasma spraying; Spray plasma spraying is a material surface strengthening and surface modification technology that can make the substrate surface have wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, thermal insulation, radiation protection, reduced grinding and sealing performance.
