Deposition Coating of Magnesium Alloys with Pure Magnesium

Abstract

Coating on surfaces of magnesium alloy with pure magnesium by applying a retort method to purification and deposition of magnesium has been attempted for improving corrosion resistance. Magnesium with three nine purity was evaporated in a vacuum furnace and deposited on a substrate, AZ31 magnesium alloy, put at a lower temperature zone in the furnace. Elemental conditions for the deposition coating technique have been investigated to obtain homogeneously coated specimens in microstructural and morphological points of view. The coated specimen has shown a superior corrosion resistance compared with uncoated AZ31 alloy.
