Abstract

This paper investigates the effect of in-situ steam time on the growth and corrosion resistance of the steam coating (SC) on the surface of LA103Z Mg-Li alloy. The morphology and phase of the SC were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FT-IR). The corrosion resistance of the coating was studied by hydrogen evolution and immersion test. In addition, the growth mechanism and corrosion resistance mechanism of steam coating were also analyzed. It was found that the density and thickness of the coating increased with the extension of in-situ steam time. However, excessive extension of the in-situ steam time will lead to the destruction of the porous and dense membrane structure. It can be seen from the results of the immersion experiment that the minimum hydrogen evolution per unit area of SC-6 h after eight days of immersion is only 8.71 mL/cm2, which is much smaller than the base body (37.74 mL/cm2).


Keywords: Mg-Li Alloy, LDH, In-situ steam coating, GRowth, COrrosion resistance.
