Abstract
A surface preparation process has been developed for titanium and titanium alloy substrates that greatly improves the resulting bond. The process improves bond strength, fracture toughness, durability and failure mode of adhesive bonds. The process also decreases the sensitivity of titanium substrates to processing variables such as humidity, temperature and hence the processing timelines. The process involves treating a titanium or titanium alloy surface with a soluble silicate solution, such as an alkali metal metasilicate, and subsequently treating the surface with a solution of an organofunctional silane. Employing this two step process, bonding to the titanium substrate is improved.
