Abstract
The effect of ion implantation on the aqueous corrosion resistance of Zr-4 in deaerated 1N H2SO4 was studied with the potentiokinetic techni que. The Zr-4 alloy was bombarded with 5 X 10(14)-2 X 10(16) Ar/cm(2) of 190 keV. It was found that the passive current density of Zr-4 decr eases with increasing implantation dose. Photoelectrochemical results show that the ion implantation of Ar in Zr-4 raises the flatband poten tial of its passive film. AES was employed to analyze the surface of t he passive film of Zr-4. The decrease in passive current density may b e attributed to a thickening oxide layer on Zr-4 and a decrease in con centration of oxygen vacancies in its passive film.
