Microstructure Research of Magnesium with Laser Surface Cladding by Al-Si Alloy

Abstract:

Using laser clads magnesium surface with Al-Si eutectic powder, analyzing the organization and composition of the cladding layer with scanning electron microscopy and EDS. The results show that the cladding layer mainly composed of β (Mg17Al12) phase, α (Mg) + β (Mg17Al12) eutectic, α(Mg) solid solution, Mg₂Si phase composition, and cladding layer and the substrate combined well, pores and cracks weren^,t found. Laser heat treatment of the cladding layer, then the bulky Mg₂Si phase was blown, small blocks were distributed in the grain boundary and improve the performance of the cladding layer.
