钢铁表面防腐硅烷膜表面涂层

Study of Silane Film for Metallic Surface Resisting Corr

研究了硅烷试剂直接用作金属表面防腐涂层的优越性及替代磷化技术的可能性 ,对在优选出的工艺操作条件制得的硅烷试剂膜 ,采用反射红外光谱对制得的膜进行成分和结构分析 ,用椭圆光谱法测定涂层厚度 。

Silane agent is applied directly for metallic surface corrosion resisting, which can replace phorsphating technique.SA film is prepared under the optimal processing conditions, and reflective FTIR spectroscopy is used to analyse component and structure of SA film. Film thickness is detected by elliptical spectroscopy method, and results of electrochemical corrosion processing detecting and CuSO 4 solution point corrosion experiment are used to verify corrosion resistance of SA film.
