CERAMIC SINTERED BODY, INSERT, CUTTING TOOL, AND FRICTION STIR WELDING TOOL
To provide a ceramic sintered body with suppressed initial wear, and to provide an insert, a cutting tool and a friction stir welding tool using the same.SOLUTION: A ceramic sintered body, which comprises AlOand WC, in which at least one element selected from the group consisting of Group 4 elements is present in the boundaries of (1) and (2) of the following, that is, (1) grain boundaries between AlOcrystal particles and (2) grain boundaries between AlOcrystal particles and WC crystal particles. In analysis by XPS on the constituent elements of the surface of ceramic sintered body, the relationship between its peak area S1 derived from WOand its peak area S2 derived from WC satisfies the following Equation 1. (Equation 1) 0.05≤S1/(S1 + S2)≤0.5.SELECTED DRAWING: Figure 1
【課題】初期摩耗が抑制されたセラミックス焼結体を提供するとともに、初期摩耗が抑制されたセラミックス焼結体を用いたインサート、切削工具及び摩擦攪拌接合用工具を提供する。【解決手段】セラミックス焼結体は、Ａｌ２Ｏ３とＷＣとを含み、下記（１）、（２）の一方又は両方の粒界に４族の元素から選択される少なくとも１つの元素が存在する。（１）Ａｌ２Ｏ３結晶粒子間の粒界（２）Ａｌ２Ｏ３結晶粒子とＷＣ結晶粒子の粒界セラミックス焼結体は、ＸＰＳによるセラミックス焼結体の表面の構成元素の分析において、ＷＯ３由来のピーク面積Ｓ１と、ＷＣ由来のピーク面積Ｓ２と、は、以下の式１を満たす。（式１）０．０５≦Ｓ１／（Ｓ１＋Ｓ２）≦０．５【選択図】図１
