“…Among these, coating has been demonstrated to be one of the most effective approaches. At present, coating techniques used to modify Mg alloy for corrosion control mainly include physical vapor deposition (PVD), 5 sol–gel, 6 micro-arc oxidation, 7 and plasma electrolytic oxidation. 8 Among these, sputtering deposition, a commonly used PVD method of coating fabrication, can produce a coating consisting of different materials, including inorganic, organic, and metals.…”
