摘要：
To improve the sliding wear resistance of AZ91D magnesium alloy, Cu-based amorphous composite coatings made Of Cu(47)Ti(34)Zr(11)Ni(8) and Cu(47)Ti(34)Zr(11)Ni(8)+20 wt pct SiC powders were fabricated on AZ91D magnesium alloy by laser cladding, respectively. SEM (scanning electron microscopy), EDS (energy dispersive X-ray spectroscopy), XRD (X-ray diffraction) and TEM (transmission electron microscopy) techniques were employed to study the phases of the coatings. The results show that the coatings mainly consist of amorphous phase and different intermetallic compounds. The reason of formation of amorphous phase and the function of SiC particles were explained in details.
