Abstract
A surface treatment, especially for titanium and aluminum alloys, forms a Si—Y sol-gel film covalently bonded on the metal surface to produce strong, durable adhesive bonds between the metal and an organic adhesive without using toxic chemicals and while significantly reducing or eliminating rinse water requirements of traditional anodizing or etching processes. The sol should produce bonds in a single application comparable in strength and performance to standard anodize controls. Parameters affecting performance include the sol composition, the ratio of silicon to yttrium in the sol, the ratio of other sol ingredients, the concentration of the sol, the carrier solvent, solution age, catalysts, surface pretreatment, application method, curing process, and primer used.
