Abstract

Ion implantation and ion mixing are applied to improve the corrosion behavior of two uranium alloys: UV0.2 and UTi0.75, in three specific media: hydrogen, humid air and salt fog. This experiments shows particularly that high dose nitrogen implantation might be effective for both corrosive environment, hydrogen and humid air. Ion mixing of aluminum coatings on UTi0.75 alloy induces microcracks in these films and reduce their protective characters in salt fog medium.
