“双层金属布”硬质涂层耐磨性能的研究

对复合在钢基体上的WC-Ni-Fe-Co系“双层金属布”硬质涂层的相对耐磨系数ε进行了测定，对比耐磨件是HRC60的高速钢，实验采用磨粒磨损和摩擦磨损，实验结果表明WC-Ni-Fe-Co系“双层金属布”涂层耐磨性明显优于高速钢（HRC60），涂层耐磨性主要与WC相含量有关。

Study on wear resistance of hard coatings produced by double powder alloy sheet process

The wear resistance coefficient of the hard coating s on the steel produced by WC-Ni-Fe-Co double powder alloy sheet process was measure d. The high-speed steel HRC60 were used for comparing with the hard coatings. T he coatings were weared by metal abrasives and rubbed with the metals. The exper imental results prove that the wear resistance of the WC-Ni-Fe-Co coatings was higher than that of the high-speed steel HRC60 obviously. The wear re sistance of the coatings was inf luenced by the contents and distribution of the WC in the coatings.
