  • Patent number: 4938850
    Abstract: A method for application of an adherent nickel plate to titanium includes steps of surface preparation, deposition of nickel from a plating solution, and a final treatment. The surface preparation steps include a hydrochloric acid dip, a nitric acid/hydrofluoric acid activation, treatment to slow the re-formation of an oxide layer, and deposition of a nickel strike. The treatment to reduce oxide formation may be accomplished without application of a current, in a solution of acetic and hydrofluoric acid, in which titanium alloy has been electrolytically dissolved. Alternatively, the treatment may be performed with the piece to be plated made anodic in a solution of acetic acid and hydrofluoric acid.
