Formation of Anticorrosion Clusters on Anodic Alumina Films by Ni Ion Implantation

Abstract:

Formation of clusters with high corrosion resistance on anodic films of Aluminum by Ni ions implantation was studied. Ni ions were implanted in anodic films of 1070 aluminum at an energy of 40 keV with dose of 5.0×1017 ions/cm2. XPS analysis reveals that Ni is present in the states of metallic Ni and NiO on the surface of the anodic film. Electrochemical results show that anodic films with Ni ions implantation provide relatively higher corrosion resistance in NaCl solution. The anti-corrosion clusters on the surface of anodic films should be the main reason for better corrosion resistance of the implanted samples.
