本文介绍用CO_2激光器对20~#钢表面涂敷WC-B_4C-Co进行的激光熔覆处理,对不同扫描速度下熔覆层的显微组织和性能进行了测试和分析。结果表明扫描速度对激光熔覆组织和各种性能影响特别显著。
In this paper, laser cladding of WC-B_4C-Co coated on 20 ~ # steel with CO_2 laser is introduced. The microstructure and properties of the cladding layer under different scanning speed are tested and analyzed. The results show that the scanning speed of laser cladding microstructure and various properties particularly significant.
