Paper Title:
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.
