Description
技术领域Technical field

背景技术Background technique
目前常用的硬质合金是以钨的碳化物(WC)，钛的碳化物(TiC)的粉末为基础，以钴Go为结合剂用粉末冶金法，在真空炉或氢气还原炉中焙烧而成。为增强刀头的硬度，往往在硬质合金刀刃部分涂覆超硬涂层，但刀头寿命仍达不到理想要求，尤其是超硬涂层寿命短且易脱落，需频繁更换刀头。尤其是车削高硬度合金铸铁轧辊，其硬度可达65HRC以上，且毛坯存在夹渣、气孔、硬点等铸造缺陷，存在断续切削、对刀具造成冲击，在切削线速度约200m/min，连续使用寿命只有约30min。Currently commonly used cemented carbide is based on the powder of tungsten carbide (WC) and titanium carbide (TiC), with cobalt Go as the binder, using powder metallurgy and roasting in a vacuum furnace or hydrogen reduction furnace. . In order to enhance the hardness of the cutter head, the carbide cutting edge is often coated with a super-hard coating, but the life of the cutter head still does not meet the ideal requirements. In particular, the super-hard coating has a short lifespan and is easy to fall off, so the cutter head needs to be replaced frequently. Especially when turning high-hardness alloy cast iron rolls, the hardness can reach more than 65HRC, and the blank has casting defects such as slag inclusions, pores, and hard spots, causing intermittent cutting and impact on the tool. When the cutting linear speed is about 200m/min, continuous The service life is only about 30 minutes.
鉴于此，需要研究一种耐磨、耐高温、长寿命的超硬刀具。In view of this, it is necessary to research a superhard tool that is wear-resistant, high-temperature resistant and has a long life.
