Abstract In order to reduce the crack rate in the laser spraying clad layer, the Fe-based amorphous clad layer was prepared by using high speed laser cladding technology and greatly increasing the laser scan speed under the condition of increasing the laser power. The morphology and different phases of the clad layer were studied by means of X-ray diffractometry (XRD), optical microscopy, and electron microscopy accompanied by energy dispersive spectrometry (EDS). The relative amorphous content of the clad layer was calculated by Jade software. The temperature field and thermal stress of clad layer were simulated by COMSOL Multiphysics. It was found that the grain size, amorphous phase content, and crack rate of the clad layer changed inversely, positively, and inversely with the increase of laser scan speed, respectively. The prepared clad layer, compared with that clad with the conventional scan speed, had a lower amorphous phase content. The simulation results confirmed that increasing the laser scan speed led to the reduction of the heat input in the clad layer, thus mitigating the thermal stress and suppressing the cracking tendency of the clad layer.

Key words： Fe-based amorphous coating laser cladding crack rate amorphous phase content
