Microstructure and Properties of Fe-based Amorphous/Nanocrystalline Coating Prepared by Arc Surface Welding

Fe-based amorphous cladding layers were prepared on low carbon steel using synchronous powder feeding Fe-based amorphous powder. The formation of the Fe-based amorphous cladding layer was improved by optimising the laser cladding process parameters, which eliminated defects in layers such as cracks and pores and improved their properties. The results show that the cladding layer comprises amorphous, dendrite, and equiaxed grains. The hardness of the amorphous phase is about 1351 HV0.2, the grain size of the fine dendrites is 1.43 μm and the hardness is 1273 HV0.2. The average hardness of the overall cladding layer is 7.93 times, and the corrosion current density is ten times lower than that of the low-carbon steel substrate.
