Technical and Performance Study of Ti-Sn Composite Chemical Conversion Coating on Aluminum Alloy
SnSO4 and TiOSO4 were chosen in this paper as the main salts for preparing composite chemical conversion coating on aluminum alloy. The scope of this paper is to find out the optimal experiment process, the performance of Ti-Sn composite chemical conversion coating and tentative to analysis the microstructure of this chemical conversion coating. The optimal conditions of the concentration ratio of TiOSO4 and SnSO4 was 0.4g/L, 0.4g/L, KMnO4 1.0g/L, NaF 1.0g/L, reaction temperature 50°C、reaction time was 3min. And then different methods were used to study the performance and microstructure of the conversion coating.
