Description
の別の層は、第1層4よりも基体2の近くに位置していてもよく、また、第3層6よりも基体2から遠くに位置していてもよい。
第2層5が第1層4から剥離するおそれを小さくできる。
相対的に小さいことによって、第2層5の厚みを安定して確保し易くなる。また、第2突起12の先端角が相対的に大きいことによって、第2突起12による第3層6へのアンカー効果を高めることができるからである。
合性が大きく低下することが避けられる。
び窒化クロム(CrN)などが挙げられる。被覆層3が上記の材質を含有する表層21を有する場合には、被覆層3の耐摩耗性が向上する。また、上記の材質は有色であることから被覆層3が表層21を含有する場合には、切刃10の使用の有無を容易に判別することが可能である。表層21の厚みとしては、例えば、0.1μm〜3μmに設定できる。
作製する。プレス成形を利用して上記の混合粉末を四角板形状に成形した成形体を作製した。成形体に脱バインダ処理を施した後に、1500℃、0.01Paの真空中において、1時間焼成して基体を作製した。その後、作製した基体にブラシ加工を施し、工具において切刃となる部分にRホーニングを施した。
