Abstract

Surface modification technology on magnesium alloys has been developed by using Mg-Si thin films via a glow discharge sputtering process, in employing Mg2Si bulky materials fabricated by powder metallurgy (PM) process as targets. This is because Mg2Si sintered materials have high hardness and Young’s modulus, in particular, a superior corrosion resistance to the conventional stainless steel. The Mg-Si thin film, having 1-2µm thickness, deposited on the AZ31 substrate improved the mechanical properties, wear and corrosion resistance compared to the conventional magnesium alloys. In particular, the effect of crystalline/amorphous structures of Mg-Si thin films on these properties was investigated in detail.
