- Abstract
In this paper, the corrosion resistant coatings were fabricated on AZ91 Mg alloy by steam treatment using deionized water as a steam source. The treatment temperature was maintained at 150 ℃, while the treatment time was varied at 3, 6 and 9 h. The results showed that relatively dense steam coating can be formed on the surface of AZ91 alloy by steam treatment for 3-9 h, and the phase structure of steam coating was mainly composed of Mg(OH)2 and contained AlO(OH) and Mg-Al LDH. With the extension of the steam treatment time, the better the corrosion resistance of the steam coating, and the corrosion current density was as low as 10-7~10-8 A·cm-2, which was 3-4 orders of magnitude lower than AZ91 Mg alloy substrate (~10-4 A·cm-2).
