HIGH-HARDNESS ABRASION-RESISTANT MEMBER AND METHOD OF MANUFACTURING HIGH-HARDNESS ABRASION-RESISTANT MEMBER

To provide a high-hardness abrasion-resistant member that has high hardness and is superior in abrasion resistance, and also superior in adhesion between a base material and a hard coating film, and also to provide a method of manufacturing the high-hardness abrasion-resistant member.SOLUTION: A high-hardness abrasion-resistant member has a base material and a coating film, which has a host phase made of a material including a solid solution containing Ni and Fe, and a hard layer composed of a material including WC crystal particles, and supported by the host phase. The hard layer is preferably 0.5 μm or larger thick, and the coating film is preferably 1.5 to 5.0 μm thick.SELECTED DRAWING: None 【課題】高硬度で耐磨耗性に優れるとともに、基材と硬質な被膜との密着性にも優れる高硬度・耐磨耗性部材を提供すること、また、前記高硬度・耐磨耗性部材の製造方法を提供すること。【解決手段】本発明の高硬度・耐磨耗性部材は、基材と、被膜とを有し、前記被膜は、ＮｉおよびＦｅを含有する固溶体を含む材料で構成された母相と、ＷＣ結晶粒子を含む材料で構成され、前記母相に支持された硬質層とを有するものである。前記硬質層の厚さは、０．５μｍ以上であるのが好ましい。前記被膜の厚さは、１．５μｍ以上５．０μｍ以下であるのが好ましい。【選択図】なし
