Abstract:Magnesium and its alloys have excellent physical and mechanical proprieties for a number of applications. Unfortunately, magnesium and its alloys are highly susceptible to corrosion, this has limited its use, it is necessary to find a way to avoid corrosion. The review details the state of the art of conversion coating, including chromate, phosphate/permanganate, stannate and other processes.
Keywords:magnesium  magnesium alloys  conversion coating
