CUBIC BORON NITRIDE SINTERED BODY, AND TOOL INCLUDING CUBIC BORON NITRIDE SINTERED BODY
To provide a cubic boron nitride sintered body having excellent abrasion resistance and defect resistance and a tool using the same.SOLUTION: A cubic boron nitride sintered body includes a cubic boron nitride and a binder phase. The content of cubic boron nitride is 80.0 vol.% or over and 99.0 vol.% or under and the content of the binder phase is 1.0 vol.% or over and 20.0 vol.% or under. The binder phase includes W2Co21B6. Moreover, the binder phase includes Ru and/or Rh. When x-ray diffraction peak strength of (420) face of W2Co21B6 included in the binder phase is shown as I1, and x-ray diffraction peak strength of (111) face of cubic boron nitride is shown as I2, 0.1≤I1/I2≤1.0 is satisfied.SELECTED DRAWING: Figure 1
【課題】耐摩耗性及び耐欠損性に優れた立方晶窒化硼素焼結体及びそれを用いた工具を提供する。【解決手段】立方晶窒化硼素焼結体は、立方晶窒化硼素と結合相とを含む。立方晶窒化硼素の含有量が、８０．０体積％以上９９．０体積％以下であり、結合相の含有量が、１．０体積％以上２０．０体積％以下である。結合相が、Ｗ２Ｃｏ２１Ｂ６を含む。さらに、結合相が、Ｒｕ及び／又はＲｈを含む。結合相に含まれるＷ２Ｃｏ２１Ｂ６の（４２０）面のＸ線回折ピーク強度をＩ１、立方晶窒化硼素の（１１１）面のＸ線回折ピーク強度をＩ２としたときに、０．１≦ Ｉ１／Ｉ２≦１．０を満たす。【選択図】図１
