ABSTRACT:
A method of treating articles of titanium or titanium alloy to form an adhesive receptive oxide layer includes the steps of applying to the surface to be treated a mixture of aqueous solutions of sodium hydroxide and hydrogen peroxide, maintaining the applied mixture within a temperature range in which the hydrogen peroxide is relatively stable and causing an increased rate of oxidation at the surface regions.
The increased rate of oxidation may be attained either by the addition of a catalyst to the mixture, or by impressing a voltage upon the mixture.
