Technical Applications of Tungsten Carbide Coatings？

Tungsten carbide is a compound composed of tungsten and carbon. It exhibits stable chemical properties and has a metallic luster with hardness comparable to diamond. Tungsten carbide is a good conductor of electricity and heat, and it is insoluble in water, hydrochloric acid, and sulfuric acid, but readily dissolves in a mixture of nitric acid and hydrofluoric acid. It is used in applications such as cutting tools, kiln structural materials, jet engine components, metal-ceramic materials, and resistive heating elements.

Our company possesses advanced supersonic spraying equipment, plasma spraying equipment, multiple sets of modern supersonic arc spraying equipment, and various flame spraying devices, allowing us to undertake thermal spraying projects across multiple industries. We have successfully completed a large number of thermal spraying projects using thermal spraying technology for industries such as papermaking, power generation, metallurgy, chemical engineering, petroleum, machinery, agriculture, and mining, achieving significant economic and social benefits.

Characteristics of Tungsten Carbide Coatings

Using plasma spraying and explosion spraying technologies, we apply special ceramic coatings on the surfaces of plungers and piston rods in various hydraulic cylinders and reciprocating pumps. The main advantages include:

1. Composite Structure: The ceramic coating forms a composite structure with the steel substrate, effectively utilizing the advantages of thermal spraying, resulting in high strength and corrosion resistance.
2. Low Friction Coefficient: This reduces energy consumption and minimizes friction losses.
3. Reduced Wear: There is less wear on sealing materials and counterpart components,  to decreased maintenance needs.
4. Increased Lifespan: The service life is 3 to 6 times longer than that of chrome-plated parts, making it an environmentally friendly coating technology.

Applications

This thermal spraying technology is widely applied in various fields, including petroleum, chemical engineering, synthetic fibers, food processing, power generation, metallurgy, shipping, water treatment, hydropower, and military industries.
