Influence of Cl- on Corrosion Behavior of AZ91 Magnesium Alloy in Simulating Acid Rain

摘要：

Initial corrosion behavior of AZ91 magnesium alloy in simulating acid rain containing Cl- is investigated by SEM/EDX and electrochemical method. The results show that corrosion of magnesium alloy in diluted NaCl solution was localized corrosion, and the attack only occurred around the scattered AlMn particle which induced the departure of AlMn from metal matrix. HSO3- in acid rain induced the dissolution of corrosion in α phase, β phase was not be corroded and presented in passive state. The corrosion of magnesium alloy in simulating acid rain containing Cl- was mainly induced by HSO3-, and the existence of Cl- accelerated the corrosion process.
