Pretreatment of Titanium for Subsequent Electrodeposition of Metal,

Abstract

Surface oxidation can be prevented and the adherence of Cu. Ni, Au, and Pt to Ti can be improved by forming a thin hydride film on a Ti. Hydrides can be formed by chemical etching in 0.5M HF or cathodic polarization in 0.5M HF containing 1 to 4 NH4F followed by polarization in 0.1M H2SO4. The hydride film has no effect on the mechanical properties and the sheets can be rolled less than or equal to 25 percent. The method can be used for improving the adherence of metals to Zr, Ta, and Nb. (Author)
