Technical application of tungsten carbide spraying

       

Tungsten carbide is a compound composed of tungsten and carbon. Tungsten carbide is chemically stable. Tungsten carbide is a black hexagonal crystal with metallic luster and hardness similar to diamond, and is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and is easily soluble in mixed acids of nitric acid and hydrofluoric acid. Used for cutting turning tools, kiln structural materials, jet engine components, cermet materials, resistance heating elements, etc.

Features of Tungsten Carbide Spray and Spray 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 in:



1. The ceramic coating and the steel matrix form a composite structure, which effectively utilizes the advantages of thermal spraying, with high strength, wear resistance and corrosion resistance;



2. Low friction coefficient, low energy consumption, reduce friction energy consumption;



3. Small wear on sealing packing or paired parts, reducing maintenance;



4. The service life is 3~6 times higher than that of chrome-plated parts, which belongs to the environmental protection coating technology.







application:



The thermal spraying technology is widely used in petroleum, chemical, chemical fiber, food, electric power, metallurgy, shipbuilding, water treatment, water conservancy, military and other fields.

Thermal spraying technology has undertaken a large number of thermal spraying projects for papermaking, electric power, metallurgy, chemical industry, petroleum, machinery, agriculture, mining and other industries, and used thermal spraying technology to repair various equipment parts. Obtain good economic and social benefits.
