Description
基材21の表面にチタンの窒化物または炭化物を含む第1層22(例えば、窒化チタンアルミニウム(TiAlN)からなる層)を形成する第1層形成工程と、
第1層22の表面を覆うバリア層23(例えば、窒化アルミニウム(AlN)からなる層)を形成する第1バリア層形成工程と、
バリア層23の表面に酸化アルミニウム(いわゆるアルミナ)を含む第2層24を形成する第2層形成工程と、
を含んでいる。
本実施形態の切削工具20の製造方法では、PVDによって、基材21の表面にチタンを含む窒化物または炭化物を含む第1層22を形成し、ついで、その第1層22の表面をバリア層23で覆うので、バリア層23の表面に酸化アルミニウム(アルミナ)を含む第2層24をPVDによって形成しても、酸化チタンが生成されない。これにより、Tiを含む第1層22とアルミナを含む第2層24との界面における皮膜の密着不良を防止することが可能である。
本実施形態の切削工具20の製造方法では、第2層24を形成する前後において、それぞれバリア層23を形成することによって、Tiを含む層の上下両面側において、アルミナ層との界面における酸化チタンの発生を防止することが可能である。その結果、基材21表面の多層皮膜の密着不良を防止し、多層皮膜における密着性を改善することが可能になる。
本実施形態の切削工具20の製造方法では、バリア層23は、チタンと異なる金属の窒化物または炭化物を含み、高い硬度を有するので、皮膜の積層部分全体の硬度の低下を抑えることが可能である。しかも、バリア層23と第2層24との界面において酸化チタンが生成されるおそれがなく、当該界面における密着不良の発生を防ぐことが可能である。
本実施形態の切削工具20の製造方法では、バリア層23は、アルミニウムを含む金属の窒化物または炭化物を含むので、アルミニウムが含まれる第2層24と組成が類似する。そのため、バリア層23と第2層24との密着性や親和性がさらに向上する。
本実施形態の切削工具20の製造方法では、バリア層23は、窒化アルミニウムからなるので、PVDによって当該バリア層23およびアルミナからなる第2層24をそれぞれ形成する場合において共通のアルミニウムのターゲットを用いることが可能である。これにより、PVDを行うための成膜装置の小型化が可能になる。
本実施形態の切削工具20の製造方法では、第1層22は、窒化チタンアルミニウムを含むので、アルミニウムが含まれるバリア層23と組成が類似する。そのため、第1層22とバリア層23との密着性や親和性がさらに向上する。よって、第1層22、バリア層23、および第2層24は、それぞれアルミニウムを含むので、これらの積層部分全体の密着性や親和性が向上する。
また、上記の本実施形態の製造方法によって製造された切削工具20は、第1層22と第2層24との間にバリア層23が介在しているので、第1層22と第2層24との界面おいて、酸化チタンが生成されない。その結果、Tiを含む第1層22とアルミナを含む第2層24との界面における皮膜の密着不良を防止することが可能である。
