Magnesium Finishing: Chemical Treatment and Coating Practices

Since the introduction of high purity magnesium die cast alloys, AZ91D and AM60B, many examples can be given of their ability to resist corrosion and accept a variety of decorative finishes.

This paper will review the common finishing options available and the requirements for their proper application to die cast parts. The finishing systems employed in a number of commercial applications, past and present, using magnesium will be described.
