Abstract

ステンレス鋼製の基材と、基材の表面の少なくとも一部に被覆された中間層と、中間層の表面の少なくとも一部に被覆された非晶質炭素膜と、を備える高耐食性部材は、少なくとも基材の表面の温度が４５０°C以下の低温で、中間層および非晶質炭素膜が形成されてなる。また、表層部が窒化処理されたステンレス鋼製の基材と、基材の表層部の表面の少なくとも一部に被覆された非晶質炭素膜と、を備える高耐食性部材は、少なくとも基材の表面の温度が４５０°C以下の低温で、窒化処理および非晶質炭素膜の形成が行われてなる。 上記の高耐食性部材は、製造工程において、ステンレス鋼製の基材の表面が、高温（＞４５０°C）に曝されない。そのため、基材の耐食性は、元のステンレス鋼の耐食性と同等に保たれる。
