Tungsten carbide is a compound composed of tungsten and carbon. The molecular formula is WC and the molecular weight is 195.85.
Basic Features:
It is a black hexagonal crystal with a metallic luster and a hardness similar to that of diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but soluble in nitric acid-hydrofluoric acid mixtures. Pure tungsten carbide is brittle, and if mixed with a small amount of titanium, cobalt and other metals, the brittleness can be reduced. Tungsten carbide is used as a cutting tool for steel and is usually added with titanium carbide, tantalum carbide or their mixtures to improve explosion-proof performance. Tungsten carbide has stable chemical properties. Tungsten carbide powder for cemented carbide production materials.
application:
Tungsten carbide coating is widely used in paper industry evaporator, dryer, furnace wall life enhancement repair, surface enhancement repair of various rolls, centrifugal pump, axial flow pump, steam boiler, valve and rotary shaft sealing sleeve mixer repair .
Advantages of tungsten carbide spraying:
1. high density coating
2. High bond strength and abrasion resistance
3. Porosity is less than 1%
4. The degree of oxidation of the coating material is low. Low carbon loss and high coating hardness.
