| description | To provide a ceramic member that has high toughness.SOLUTION: A ceramic member of the present disclosure is the ceramic member composed of a ceramic substrate that includes a plurality of first particles containing 90 mass% or more of tungsten and carbon in total amount and a plurality of second particles containing aluminium and oxygen. The substrate further has a columnar body that includes a plurality of third particles containing less than 90 mass% of tungsten and carbon in total amount and containing chromium and titanium. The columnar body has an average length axis length of 40 μm or more in the cross section orthogonal to the surface of the substrate. A tool of the present disclosure comprises the ceramic member, and a cutting tool of the present disclosure comprises a holder extending toward the second end from the first end and having a pocket at the first end side, and the tool located in the pocket.SELECTED DRAWING: Figure 2
【課題】高い靭性を有するセラミック部材を提供する。【解決手段】本開示のセラミック部材は、タングステンおよび炭素を合計で９０質量％以上含有する複数の第１粒子と、アルミニウムおよび酸素を含有する複数の第２粒子と、を有するセラミックスの基体からなるセラミック部材である。前記基体は、さらに、タングステンと炭素を合計で９０質量％未満含有し、クロムおよびチタンを含有する複数の第３粒子を含む柱状体を有する。該柱状体は、前記基体の表面に直交する断面における平均長軸長さが４０μｍ以上である。また、本開示の工具は、上述のセラミック部材を備える。また、本開示の切削工具は、第１端から第２端に向かって延び、前記第１端側にポケットを有するホルダと、前記ポケットに位置する上述の記載の工具とを備える。【選択図】図２ |
