本文介绍了在45钢表面利用大功率CO_2激光束制取硬质合金WC-TiC-Co的方法,并对合金层的显微组织和性能进行了观察和测试,对形成硬质合金的机理作了初步讨论,结果表明;采用这种方法对提高金属材料表面性能是成功的。

This article presents a method of making hard alloy WC-TiC-Co on the No.45 steel surface by using high power laser beam. The microstructrue and performance of the alloyed layer are observed, examined and analyzed, and the mechanism of forming hard alloy is studied. The results indicate that it is very successful to improve the properties of the metal material's surface with this method.
