Tungsten carbide spraying

Tungsten carbide belongs to the ceramic phase, which has high melting point, high hardness, poor conductive thermal conductivity, stable chemical performance advantages, is an ideal material preparation of wear-resisting corrosion resistant coating, but due to the high melting point and high hardness, tungsten carbide coating material of tungsten carbide particles and matrix adhesion is poor, and prone to oxidation when raise the temperature in the air, so pure tungsten carbide powder rarely used for thermal spraying powder materials alone, often need to add Co, Ni, Ni - Cr made of metal or al
