Titan alloys have to be pretreated to increase the adhesive bonding strength. Because of environmental reasons dry chemical pretreatment methods are preferred compared to wet chemical techniques. One successful method is a silicatisation referring to the Saco-technique. Layers generated by this method on titanium or polymer substrates lead to highly water-resistant adhesive bondings. Also adhesive joints of Ti with polymer show high bond strength when polymer and Ti are Saco treated. With a suitable optimization of the technological parameters it is possible to adhesively bond polymers also with anaerobic acrylic esters.
