In this study, Mg alloy-based composites (MMC: metal matrix composite) with uniaxially oriented continuous SiC fibers were fabricated using a low-pressure infiltration method. Next, the influence of Al particles as promoter on interfacial reaction between and alloy was investigated by means scanning electron microscopy (SEM) energy dispersive X-ray (EDX) analysis. presence particles, β-Mg17Al12...

The effect of Mg addition on the microstructure and sacrificial anode protection performance a hot-dip Al-5Zn-4Si-xMg coating was studied by scanning electron microscopy (SEM-EDS), an X-ray diffractometer, electrochemical workstation. results showed that Al-Zn-Si alloy composed Al-rich phase Zn-rich phase. MgZn2 appears after addition. When increased to 0.15 wt.%, Mg2Si began appear in alloy. c...

Al-Si/7.5 wt.%Y2O3 coatings were prepared on Mg alloy with laser cladding to enhance the wear and corrosion resistance of substrate. The influence power microstructure properties coating discussed. results uncovered that consisted primarily Mg2Si, Mg17Al12, Mg2Al3, Al4MgY, α-Mg phases. Through calculating, it was observed crystal size decreased decrease in power. Y2O3 gave a better strengthenin...
