Characteristics of tungsten carbide spraying and sprayed tungsten carbide: Using plasma spraying and explosive spraying technology, special ceramic coatings are sprayed on the surfaces of plungers and piston rods in various hydraulic cylinders and reciprocating pumps.
Mainly manifested in
1. The ceramic coating forms a composite material structure with the steel substrate, effectively utilizing the advantages of thermal spraying, with high strength and wear and corrosion resistance:
2. Low friction coefficient, low energy consumption, reducing frictional energy loss:
3. Low wear on sealing packing or mating parts, reducing maintenance:
4. Service life is 3 to 6 times better than chrome-plated parts, belonging to environmentally friendly coating technology.
Application: This thermal spraying technology is widely used for reciprocating pump plungers, hydraulic cylinder piston rods, etc., in fields such as petroleum, chemical industry, chemical fiber, pharmaceuticals, food, electric power, metallurgy, shipbuilding, water treatment, water conservancy, and military industry.
