| Abstract: |
| In order to improve surface properties of magnesium alloy, Al coating on the AZ31 magnesium alloy was prepared by the thermal spraying,and the Al-rich layer was obtained by pulse current gas tungsten arc melting. The microstructure and properties of the alloying layer were analyzed. The results show that the alloying layer has a typical dendritic structure, the alloying layer consistes of phases of Mg2Al3, Mg17Al12,α-Mg and Al. The microhardness is increased from about HV50 to about HV200. The potentiodynamic polarization results confirmed that the corrosion resistance is enhanced. |
