PROBLEM TO BE SOLVED: To impart tough properties to the impact of pressure and heat to a diamond composite wear-resistant member.SOLUTION: A method of producing high-toughness wear-resistant composite material includes: setting an appropriate sintering temperature from 900 to 1,080°C by adjusting a ratio of phosphor in a material, wherein the material contains hard particles including diamond particles and WC particles, a binder of an iron group metal containing phosphor (P), and copper, which is distributed and is present alone; and performing hot press sintering or electric discharge sintering on the material. The composite wear-resistant member includes a material including hard particles including diamond particles and WC particles, a binder of an iron group metal containing phosphor, and copper. The phosphor content is from 0.01 to 1.0 wt.% with respect to the sum total of the WC particles and the binder. |
