| Abstract: | To improve the sliding wear resistance of AZ91D magnesium alloy,Cu-based amorphous composite coatings made of Cu47Ti34Zr11Ni8 and Cu47Ti34Zr11Ni8+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 a... |
