چکیده انگلیسی
Laser cladding of crack-free Fe-based amorphous coatings remains a challenge due to their intrinsic brittleness and the generation of huge thermal stress during the laser process. In this paper, we have applied a triple laser scanning strategy, which incorporates a first laser scan to heat the substrate, a second laser scan to produce amorphous coating, followed immediately by a third laser scan to in-situ release the thermal stress formed within the amorphous coating, to prevent the generation of crack during the laser cladding of an Fe37.5Cr27.5C12B13Mo10 amorphous coating. The microstructure and wear resistance of the crack-free Fe-based amorphous coating were also examined.
