You may want to know what tungsten carbide coating is?

Tungsten carbide coating is a high-performance surface coating mainly composed of tungsten carbide (WC), which has ultra-high hardness, wear resistance, corrosion resistance, and high temperature resistance. It is widely used in industrial, aerospace, energy, medical and other fields.

Composition of tungsten carbide coating

Main component: tungsten carbide (WC), with a hardness second only to diamond (microhardness above 2000 HV).

Adhesive phase: usually cobalt (Co), nickel (Ni), or cobalt chromium (Co Cr) alloys, used to enhance toughness and bonding strength.

Optional additives: such as chromium carbide (Cr ∝ C ₂), vanadium carbide (VC), etc., to optimize specific properties.
