Self-fluxing Fe-Cr-Ni-B-Si alloy prowders are laser clad on medium carbon steel substrate of dimensions 80×35×10mm〓. The investigation results of this clad layer are: micro-defects, micro-cavity and occluded forin substance, are the micro-cracks and crack resourses in clad layer; crack of coating propagates along the boundary of two kinds of eutectic sutructure; The included angle θ between the cracking direction and laser scanning direction in multitrack overlapping clad is smaller than that in one-track clad because of crack propagating along crystalline growth direction and crystalline direction in overlapping zone being different from it in one-track clad.
在调质态的45〓钢表面，采用预置粉末法进行FeCrNiBSi合金的多道搭接激光熔覆，对其熔覆层进行分析表明：多道搭接激光熔覆层裂纹扩展方向与激光扫描方向间的夹角θ与单道熔覆时相比明显变小，前者θ0°，后者θ角基本都为90°，这主要是因为多道搭接时，搭接区结晶方向发生了变化以及裂纹沿结晶方向扩展所致；激光熔覆层裂纹大多是以覆层与基材交界面的孔洞、熔覆层内不同方向共晶团间的显微缩孔、夹杂物的边界等三种显微缺陷作为裂纹源，并沿低熔点物相形成元素偏析造成弱化膜的共晶团界面扩展延伸。
