Effects of current output modes on the growth kinetics and corrosion resistance of micro-arc oxidation coatings on magnesium alloy
نویسندگان
چکیده
Abstracts Micro-arc oxidation (MAO) coatings were prepared on the AZ31 Mg alloy under constant/gradient current control modes. The effects of output modes growth rate, energy consumption, microstructure, and corrosion resistance MAO studied. results shows that step-down mode (G852) exhibited a lower unit consumption than constant (C5) step-up (G258), even though same average density was used during process. Meanwhile, G852 is conducive to thick dense coating, resulting in better resistance. method saving preparation resistant coating by adjusting great significance for practical production.
