Abstract:
Being light and easy of recycling, magnesium alloys have become the preferred materials for lightweighting in equipment manufacturing industry owing to their excellent structural performance and many other advantages; and compared to steel, magnesium alloys have distinct advantages in terms of reserves, properties, application recycling, energy saving, and environmental protection. Firstly, the role of magnesium alloys in modern industry development and major problems appeared in practical application of magnesium alloys were introduced, and then the corrosion mechanism of magnesium alloy, effects of various factors on the corrosion behavior of magnesium alloys, and the electrochemistry corrosion mechanism of novel rare earth magnesium alloy were summarized. Finally, several prospective surface treatment technologies of magnesium alloys were briefed, and the future development trends of magnesiums corrosion and protection were put forward.
