Pd-Based Metallic Glass Films Formed by Electrodeposition Process

Abstract

The formation of Pd-Ni-P and Pd-Ni-Cu-P metallic glass films using the electrodeposition method was examined. In this study, the structure and composition of these metallic alloys were investigated at various condition of electrodeposition. The X-ray diffraction pattern on the electrodeposited Pd-Ni-P films in the range of 18-69 at% Pd, 12-62 at% Ni and 9-21 at% P showed a broad diffraction peak, which indicates metallic amorphous structure. A result of DSC showed that the electrodeposited Pd-Ni-P films in the range of 36-57 at% Pd, 24-47 at% Ni and 16-21 at% P were metallic glasses. In addition, it was proven that the electrodeposited Pd₅₄Cu₈Ni₂₂P₁₆ film was metallic glass.
