摘要
通过水热法制备片状纳米磷酸钡,利用电化学阻抗谱和盐雾试验测试方法,研究纳米磷酸钡对环氧涂层耐蚀性的影响。研究发现,环氧涂层中纳米磷酸钡与金属基体腐蚀产物Fe O反应生成不溶性Fe PO4,在腐蚀区形成隔离层,进而提高涂层的耐蚀性,在本实验中添加5%片状纳米磷酸钡环氧涂层的耐蚀性最高。
Nano- flake barium phosphate was prepared by hydrothermal synthesis, and then the effect of which as pigment on the corrosion behavior of epoxy coating was investigated by means of electrochemical impedance spectroscopy（EIS） and salt spray tests. The results show that the nano-flake barium phosphate in the epoxy coating can react with iron oxide, the corrosion product of metal substraste,to generate an insoluble Fe PO4 as a barrier on the corrosion spot, thereby to enhance the corrosion resistance of the coating; Among others, an epoxy coating with 5 mass% nano flake barium phosphate shows the highest corrosion resistance.
