| 摘 要： | 针对镁合金化学性质活泼、不易直接涂装等特点，研究开发了一种主要由微米金属粉、有机硅烷等组成的新型环保水基金属防护涂层.中性盐雾试验、3.5%NaCl溶液浸泡、电化学阻抗和附着力测试等研究结果表明，该涂层具有良好的结合力、耐热性以及对基体的防护性能.用扫描电子显微镜(SEM)等分析手段研究了涂层的片状层叠组织结构，并探讨了涂层的成膜机理与防护作用.

| Abstract: | Due to its active chemical property, magnesium alloy is hard to be directly applied with paints on its surface. Therefore, a new enviromental friendly water based paint with metallic pigment was developed, which contains metal powder of micro meters in size and organosilane compound etc. The properties of coatings were investigated by neutral salt spray test, 3.5 % NaCl solution immersion test, electrochemical impedance mesurement and adhension test. Results showed that the paint can achieve good adhesion, better heat resistance and excellent protectiveness for magnesium alloy. The layered microstructure of the coating was studied by Scanning Electron Microscopy. The corrosion mechanism and the protection performance of the coating was also discussed. |
