Patent ID: 7465234

Claim:
A method for preparing a titanium-alloy material hybrid fastening system, comprising the steps of: forming a titanium or titanium-alloy material threaded pin component; forming a mating titanium or titanium-alloy material swage collar component, wherein at least one of the threaded pin component and the swage collar component is formed of an ultra-fine grain titanium material or an ultra-fine grain titanium-alloy material; applying a corrosion-resistant, curable organic coating material to a titanium or titanium-alloy material threaded pin component and to a titanium or titanium-alloy material swage collar component having internal dimensions approximating the dimension of and conformable to the threads of the threaded pin component wherein the coating material comprising a phenolic resin and an organic solvent; and curing the coating material after application to the threaded pin and swage collar components, wherein at least one of the threaded pin component or the swage collar component is not fully heat-treated prior to coating and is subsequently heat-treated concurrently with the curing of the coating material.
