Introduction of Tungsten Carbide Spraying Performance

Tungsten carbide is a compound of tungsten and carbon. It is a black hexagonal crystal with metallic luster and similar hardness to diamond. It is a good conductor for electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and soluble in mixed acid of nitric acid and hydrofluoric acid. Tungsten carbide spraying is to combine tungsten carbide alloy with base material in the form of coating to form tungsten carbide wear-resistant layer. Tungsten carbide spraying has the advantages of high hardness, excellent wear resistance and long life, which promotes the rapid development of CNC tools.


Operation Flow 1: Make tooling according to drawings to protect areas that need protection. 2: Sandblasting and polishing surface treatment to increase the adhesion of coatings. 3: Choose a reasonable running device according to the workpiece. The main thing is more preparatory work in the early stage.


Coated tungsten carbide materials are mainly divided into coatings and cemented carbide matrix. The process of coating is a process of physicochemical reaction and film formation. The performance and surface state of the substrate must meet the requirements of the coating. The coating must be combined with the appropriate substrate to achieve the desired performance.
