The laser cladding method was selected to prepare Fe₄₇Cr₁₅Mo₁₄Co₃C₁₅B₆ amorphous coating on H13 steel surface. The structure morphology and surface properties of the cladding layer under various laser scanning speeds were compared, which were analyzed through scanning electron microscope, electron probe and X-ray diffraction to represent the micro microstructure and phase distribution of the cladding layer. The results show that, with the increase of scanning speed, there is obvious changes of the microstructure of the cladding layer. When the scanning speed was 50 mm/s, the cladding layer was made up of large amount of crystalline phase and small amount of amorphous phase. When the scanning speed was 80 mm/s, the proportion of amorphous phase in the cladding layer increased obviously, and the crystalline phase diffused in the amorphous region. When the scanning speed further increased, the amorphous phase content increased as well. In addition, with the increase of scanning speed, the hardness and corrosion resistance of the cladding layer increased greatly as well, which indicates that the amorphous phase amount has a significant influence on the properties of the cladding layer.

选用激光熔覆法制备Fe ₄₇ Cr ₁₅ Mo ₁₄ Co ₃ C ₁₅ B ₆非晶体涂层对H13钢表面。在各种激光扫描速度的包层的结构形态和表面性质进行了比较，其是通过扫描电子显微镜，电子探针和X射线衍射分析，以表示包层的微微观结构和相位分布。结果表明，随着扫描速度的增加，有包覆层的微观结构的明显变化。当扫描速度为50毫米/秒，包覆层由大量的结晶相和非晶相的少量的向上。当扫描速度为80毫米/秒，非晶相的在包覆层中的比例显着增加，并且在无定形区结晶相扩散。当扫描速度进一步提高时，非晶相含量也增加。另外，随着扫描速度的增加，包覆层的硬度和耐腐蚀性大大提高为好，这表明非晶相量对包覆层的性能产生影响显著。
