ABSTRACT
The corrosion performance of these types of bis-sulfur silane films on AA 2024-T3 was evaluated by a salt immersion test (i.e., 3.5%NaCl aqueous solution, pH 7). After 7 days o f immersion, no significant difference was seen between these two types of silane films (Figure 9). This indicates that different organic solvents do not have a noticeable effect on the corrosion performance, although they do affect the film structures by influencing the hydrolysis o f the bis-sulfur si lane in different ways. Based on this result, another interesting conclusion can be drawn here that a completely hydrolyzed silane solution is not necessary for op timum corrosion protection o f AA 2024-T3.
