Si-69应用于2024铝合金表面硅烷化防腐蚀处理的工艺研究
Studies on Silane-based Anti-corrosion Surface Treatment of Aluminum Allov 2024
摘要
Abstract
The hydrolysis conditions of 3 ,3'-bis[triethoxysilylpropyl]tetrasulfide (Si-69) were probed by the orthogonal design. The influence of film-forming factors such as the dosage of Si-69, the PH value of hydrolization, the time of hydrolization, the aging time and the aging temperature on the corrosion resistance of silane films was also studied. The best anti-corrosion technology was systematically identified. The electrochemical tests showed that the silane films effectively reduced the surface porosity of aluminum 2024 and prevented the cathode active sites reduction reaction which the corrosion particles participated in.关键词
