Abstract

Uranium and uranium alloys are a kind of important nuclear materials with unique physics and chemical properties. Unfortunately, it is eroded easily, especially in humid environment. In this paper, Ni coating and Ni+Zn composite coating were prepared on the surface of U–Ti alloy. The adhesion strength, phase structure and corrosion properties were characterized by tensile method, X-ray diffraction and electrochemical methods. The results showed that the Ni coating was a face centered cubic structure, while the anodic Ni+Zn composite coating was hexagonal structure. The average adhesion strength of composite coating was 16.0 MPa. The corrosion protection of composite coating was mainly due to the electrochemical protection of Zn coating and the physic barrier function of Ni coating.
