Metal ceramic coatings WC Tungsten Carbide Nanoparticles
Sintering the head of pick cutting in engineering and mining for metal ceramic coatings, which can significantly improve the wear resistance of the denticle, to improve the lifetime of pick cutting by 2 ~ 5 times.
Coating technology is an important branch of metal surface strengthening technology, on the basic of not destroying the basic mechanical properties of metallic materials, the wear-resisting, corrosion resistant and high temperature resistance and other mechanical and physical and chemical properties are improved. Tungsten carbide composite metal ceramic coatings have the characteristics of spalling resistance, impact resistance and wear resistance, which will have great significance to consumable tool, such as pick cutting. as shown in figure 1, after sintered tungsten carbide metal ceramic coating in pick cutting head, the life improved by 2 ~ 5 times.

The formation of metal ceramic coating is to focus enough heat energy on the substrate metal surface, in a very short period of time melting the coating alloy coated on the surface of the substrate and infiltration substrate surface to make interface react and diffuse between the coating binding phase (self fluxed alloy) and substrate. The shear strength and tensile strength of diffusion metallurgical bonding equates high temperature brazing (400 ~ 1000 mp), affordable enough to meet the mechanical load of the mining tools working conditions required.
