Abstract

Abstract: Taking Mg-1.5Zn-0.5Ca-0.8Ce alloy as the research object,alloying and solution treatment were carried out respectively to study the effect of Zr addition and solution treatment on the corrosion resistance of magnesium alloy Mg-1.5Zn-0.5Ca-0.8Ce,and to explore the mechanism of alloying and heat treatment on the corrosion resistance of magnesium alloy.The results show that both the addition of Zr and the solution treatment can effectively improve the corrosion resistance of the material,among which the Mg-1.5Zn-0.5Ca-0.8Ce-0.7Zr magnesium alloy specimen solution treated has the best corrosion resistance.It can be concluded that both the alloying and heat treatment have important effects on microstructure and corrosion resistance of the magnesium alloy.

Key words: magnesium alloy, solution treatment, alloying, corrosion resistance
