ABSTRACT:
A method of treating a titanium or titanium base alloy surface prior to the electroplating of a metal thereon in which the surface is immersed in a solution containing hydrofluoric acid, ammonium bifluoride and dimethylformamide. Reaction between the solution and the surface results in a coating being deposited on the surface which provides better adhesion between the surface and any metal subsequently electroplated thereon.
