The Characteristic of ceramic coatings prepared on magnesium alloy AZ91D by micro-arc oxidization in silicate electrolyte Xichang Shi1,a, Xiang Xiao1,b, Baizhen Chen1,c, Wei Shang1,d 1School of Metallurgical Science and Engineering, Central South University, Changsha 410083, China axichang.shi@gmail.com, bxgirl83@163.com, cyhschen@mail.csu.edu.cn, dshangw13@163.com Keywords: Magnesium alloy AZ91D, MAO coatings, Corrosion resistance Abstract.
Rectangular samples (with dimensions 35 mm×20 mm×3 mm) of Magnesium alloy AZ91D (Al 8.8 %, Zn 0.81 %, Mn 0.21 %, Si 0.026 %, Be 0.001 %, Fe 0.002 %, Cu 0.0024 %, Ni 0.00032 %, Mg rest) were used as substrate material.
The electrochemical corrosion experiments and the immersion results show that the corrosion resistance of micro-arc oxidation ceramic coating is obviously improved in comparison with the one of original material.
