This paper developed some new methods to improve corrosion resistance of magnesium alloy and solve its poor corrosion resistance the problem in application. After analysing the mechanisms of pretreatment and deposited process of electroless Ni plating, a new electroless Ni plating process was developed. After the tranditional electroless plating method was broken, a new idea-clad electroless plating process was proposed by using organic coating and electroless plating, the surfaces of magnesium alloy...
