Abstract
The excessively high corrosion rate of magnesium alloy in human body seriously inhibits their clinical applications. Micro-arc oxidation (MAO) can improve the corrosion resistance and bioactivity of Mg alloy. However, the generated wastewater during MAO treatment may threaten aquatic ecosystems. Calcium hydroxy-methionine (MHA-Ca), one kind of amino acid-chelated Ca, was selected for the first time as the Ca source and its influences on coating formation were systematically investigated. The results show that the coating produced in the base solution with 1 g/L MHA-Ca achieves excellent corrosion resistance. MHA-Ca is highly sensitive for the increased concentration and solution pH value, and can…
