Effects of sealing treatment on corrosion resistance and degradation behavior of micro-arc oxidized magnesium alloy wires

► We develop three different sealing treatments for the oxidized magnesium alloy wire. ► We compare effects of three sealing treatments on corrosion resistance in SBF. ► MAO magnesium alloy wire sealed with gelatin-HA has a better corrosion resistance. ► The wire sealed with gelatin-HA exhibits reduced degradation in both SBF and SIF.
