迄今为上,高速鋼仍然是机械制造加工中消耗量最大的刀具材料之一。因此,尽一切可能改善高速鋼刀具的切削性能,采取各种合理使用的措施以提高高速鋼刀具的耐用度,从而降低其消耗量,始終是一个普遍受到关注的重大研究課題。高速鋼刀具的表面化学热处理方法以其設备簡单、操作方便、成本低廉且能有效地提高高速鋼刀具的切削性能而受到国內外热处理界和金属切削界的重視。当前,該种处理方法的发展状况是:多种工艺并
So far, high-speed steel is still one of the most consumed tool materials in machine building and processing. Therefore, to do everything possible to improve high-speed steel cutting tool cutting performance, to take all reasonable measures to improve the durability of high-speed steel cutting tools, thereby reducing their consumption, has always been a major concern of general research topics. The surface chemical heat treatment method of high speed steel cutting tools is valued by domestic and foreign heat treatment industry and metal cutting industry for its simple equipment, convenient operation, low cost and effectively improving the cutting performance of high speed steel cutting tools. At present, the development of this treatment is: a variety of processes and
