Electrochemical characterization for ion-implanted materials surfaces

Studies on the surface modification of materials by ion implantation have been carried out during the past 25 years in RIKEN. In this paper, results of electrochemical studies on the ion-implanted materials are described to realize the unique substances formed by the ion implantation. The ion implantation is used for compositional and structural surface modification of iron and carbon substrates. Voltammetric behavior of ion-implanted iron electrodes characterized effects of the ion implantation on anodic dissolution and passivation properties of the modified surfaces. Typical electrode reaction properties of ion-implanted carbon electrodes clearly were related to the effects of structural modification of the carbon surfaces.
