Abstract Pd-Ti surface alloy was produced by bombarding a Pd-plated Ti alloy with Xe ions. The electron spectroscopic profile analyses show that the distribution of Pd is quite homogeneous through the surface layer, which consists of Ti, Pd and their oxides, nitrides etc. Near the surface TiO_2 is the principal component of the passive film formed. The Pd/Ti ratio is large and decreases with depth from the surface inwardly. In boiling 1NH_2SO_4 the average corrosion rate of the Pd·Ti surface alloy is about 1/60 of Ti alloy matrix after 6 hours of immersion, and corrosion rate in the near-surface region is less by three orders of magnitude. It is expected that the Pd-Ti surface alloy by IBM would be better than the Pd-Ti bulk alloy and Pd-implanted alloy for corrosion protection.
