ABSTRACT:
The present invention relates to a method for chemically treating structures fabricated from titanium based alloy compositions which compositions inherently possess positive open circuit corrosion potentials and reduced rates of corrosion properties. The method comprises contacting said fabricated structures with an aqueous pickling solution of hydrofluoric and sulfuric acids at a temperature of at least ambient temperature. This contact is continued for a time sufficient to remove any deleterious oxide layers adhered to the surfaces of the alloy compositions of the fabricated structures.
