Lots of studies have been done for the development of new oxidation resistant or corrosion resistant magnesium alloys by the addition of minor elements which make dense oxide film preferentially on the surface and act as protective layer for the rapid oxidation at high temperature or corrosion environment. SEN alloy containing small amount of Ca and Y in AZ series alloy, initially designed for non-flammable alloy, has been reported to have excellent corrosion resistance. However, the mechanism of improved corrosion resistance of SEN alloy is not explained clearly. In this paper, corrosion behavior of SEN alloys made by various different process and tested in various corrosion environment was summarized in detail, and two approaches to explain excellent corrosion resistance of SEN alloys were suggested.
