Preparation and cutting performance study of YSZ-toughened PcBN superhard tools.

Titanium alloy, as a recognized difficult-to-cut material, places higher demands on the performance of cutting tools. Compared with the mainstream cemented carbide tools, PcBN tools have a higher life and better machining performance. In this paper, a new type of cubic boron nitride superhard tool was prepared by introducing YO-stabilized ZrO (YSZ) under high temperature and high pressure (1500 °C, 5.
