摘要
Abstract
The tungsten and cobalt elements contained in the worn cemented carbide produced by modern industry are strategic scarce resources.The recycling of worn cemented carbide has become a key priority in China's current industrial development.This paper studies the oxidation and recycling process of worn cemented carbide cutting tools.The optimal oxidation temperature of uncoated cutting tools was determined to be 923℃through thermal analysis,and the oxidation weight gain was linearly related to time.Meanwhile,SEM examination of the subsurface grain morphology after oxidation revealed two distinct stages based on morphological characteristics:a complete oxidation stage and a densification stage,thereby elucidating the evolution mechanism of the oxide layer from the surface to the interior.Simultaneously,XRD phase analysis was performed on the oxidation products of the coated tools.关键词
