Abstract

Pt-Mo alloy films were obtained by electrodeposition from a plating bath containing H2PtCl6 and Na2MoO4, using ammonia alkaline baths, and the effects of electrolysis parameters on Pt and Mo content, the total current efficiency and the structure and thermal stability of Pt-Mo alloy films were investigated under varying conditions of electrolysis.<br>Electrodeposited Pt-Mo alloy films were then studied by X-ray diffraction, DSC analysis and ESCA, and information on the structure of the alloy films was obtained. X-ray diffraction patterns showed that films containing about 10∼15 wt% Mo consisted of a mixture of amorphous and crystalline alloys. ESCA spectra of Mo 3d levels for the alloy films showed that these elements existed in a metallic state.
