Research and Progress of Galvanic Corrosion of Magnesium Alloys

In this paper,the galvanic corrosion of magnesium alloy AM60 in contact with Q235 carbon steel, 18-8 stainless steel,LY12 aluminum alloy and pure aluminum is studied,and the latest progress in the research on the galvanic corrosion of magnesium alloys is reviewed.The influential factors of the galvanic corrosion of magnesium al- loys are discussed emphatically.The measurements taken to reduce the galvanic corrosion of magnesium alloys are pro- posed.Finally,some scientific issues on the galvanic corrosion of magnesium alloys are put forward.The experimental results and discussion show that the measurements,such as a proper structure design,suitable washer selection,anti- alkali coatings on magnesium alloy and coupling metals,should be taken to prevent the galvanic corrosion.And coat- ings containing aluminum layer should be avoided being applied in the galvanic corrosion environment due to the alkali- zation of corrosion of magnesium and its alloys.
