Carbits

Carbides are materials that can undergo cryogenic processing and are commonly used in industrial applications. Tungsten carbide is used in many machines and parts operating under harsh conditions such as high temperatures and corrosion, thanks to its wear resistance and hardness. They are typically formed within a cobalt matrix along with carbide-forming elements. The homogeneous distribution of carbide structures within the matrix results in a significant increase in wear resistance. Cryogenic processing also affects the matrix material, increasing its strength.

According to scientific studies, cryogenic processing changes the microstructure of tungsten carbide. During the process, the size and number of β-phase increase, leading to an increase in the hardness of tungsten carbide by about 7%. Additionally, in cobalt matrix carbides, cryogenic processing prevents the matrix material from deforming easily.

“Cryogenic treatment of tungsten carbide reduces tool wear when machining medium-density fiberboard, Harold A. Stewart, 2004.”

“Cryogenic treatment of cutting tools, Andrew Yong, 2006.”

Cryogenic processing increases the wear resistance of carbides commonly used in industrial applications (cutting edges, drill bits, excavator bits, drill bits, etc., in many machine parts).
