Abstract

Application of adherent coatings on titanium and zirconium alloys can be problematic because of the natural oxide surface film that readily reforms on these metals after being removed. However, in spite of this obstacle, procedures have been developed for applying adherent electroplates or vacuum coatings on these substrates. These methods were quantified by means of a ring shear test wherein cylindrical rods with thick coatings were forced through hardened steel dies. In addition to these data, some solid-state bonding applications for titanium alloys and Zircaloy-2 are reviewed.
