Cemented Carbide Coated Tool Cold Treatment

Cemented carbide coated tool, the composition and nature of the binder phase matrix Co tool for strength and deformation characteristics of cemented carbide coated tool plays a vital role. If you want to change the characteristics of this ingredient and alloys, has two ways, one is the heat treatment, another is the tool cold treatment. Cold treatment cemented carbide coated tool creates a ultra-low temperature environment, the degree of supercooling is increased, so that the cobalt alloy free energy difference of the phase change increases, increasing the driving force of phase transition, thereby reducing the tool in the cutting process abrasive wear and diffusion wear. Because of the higher surface hardness and wear resistance coating material, cemented coated carbide allows a higher cutting speed, thereby improving the processing efficiency; or can greatly improve tool life at the same cutting speed.
