Tungsten Carbide Coated Tools Cryogenic Treatment

Tungsten carbide coated tools, the composition and properties of the binder phase of Co tool substrate largely determines the strength and deformation characteristics of tungsten carbide cutting tools.There are two ways to change the Co composition and properties oftungsten carbide cutting tools, one is to heat the other is for tungsten carbide coated tools cryogenic treatment, cryogenic treatment has created a super-low temperature environment for tungsten carbide coated tools, increasing the degree of supercooling of the alloy of cobalt phase change of free energy difference increases, increasing the phase transformation driving force, thereby reducing wear and diffusion tool abrasive cutting process wear. Another aspect, there is information that the coefficient of thermal expansion than the WC Co more than three times, the binder phase is the main phase of the destruction of carbide cutting tools, Co phase is present in a large thermal stresses are negative factors. Cryogenic treatment enables the WC-Co cemented tungsten carbide cutting tools get better surface residual stress.
