电弧喷涂锌铝复合涂层耐蚀性能研究

Study on Corrosion Resistance of Arc Spraying Zinc and Aluminum Composite Coatings

通过对锌铝涂层＋封闭层所组成的复合涂层体系在3．5％NaCl进行浸泡实验，改变封闭层醇酸树脂的粘度确定对复合涂层增重量的影响。经过理论分析，从而说明封闭层粘度变化对复合涂层腐蚀机理的影响。

Through the immersion test of the num coating with sealants in 3.5 % NaCl solution. ing by c sealants hanging composite coating which consisting of zinc and alumi- The impact of the weight increment of composite coatthe viscosity of alkyd resin. Through theoretical analysis, which shows the viscosity of coating changed effect on the corrosion mechanism of composite coating.
