A novel method for the preparation of Al–Mg intermetallic coating

A novel method has been suggested to obtain an Al–Mg intermetallic compound coating on the ZL102 Al alloy by Al–Mg twin-wire arc spraying and gas tungsten arc melting (GTAM) post treatment. The composition and the morphology of the coating are characterized by X-ray diffraction (XRD) and scanning el...

Zusammenfassung:A novel method has been suggested to obtain an Al–Mg intermetallic compound coating on the ZL102 Al alloy by Al–Mg twin-wire arc spraying and gas tungsten arc melting (GTAM) post treatment. The composition and the morphology of the coating are characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) and the corrosion behavior is investigated by potentiodynamic electrochemical tests respectively. The results show that the components of the coating after GTAM are Mg 17Al 12, Al 3Mg 2 and Al. According to polarization curves and micro-hardness tests, the Al–Mg intermetallic coating exhibits good corrosion resistance and high micro-hardness.
