Purpose: The aim of this paper is the presentation of the study results provided on structure and surface of the electrodeposited Ni-Mo alloys with different polymers. Design/methodology/approach: Composites based on Ni-Mo alloys with polytiophen, polypyrrole and polyethylene were obtained by electrochemical method. Depending on the potential and current density of electrodeposition and electropolymerization processes. Findings: The structural analysis made by X-ray diffraction shows that, in general, the solid solution of molybdenum in nickel is forming. The unit cell parameters of solid solution are slightly changing with the increasing of molybdenum contents in the alloy. The analysis of diffraction line broadening indicates presence of the Ni-Mo solution nanocrystallites in the deposited layers. Moreover, the Auger Electron spectroscopy (AES) verifies both the presence of the solid solution of molybdenum in nickel and presence of polymers in composites. The SEM images show the general microstructure typical for the grain structure. Research limitations/implications: Composites obtained by electrochemical method studied in this paper are unique in that the electrochemical methods can be used for processing ceramics, polymers, metals, composites and hybrid materials. Practical implications: The codeposition of alloys with polymers or polymerisation with alloy codeposition has created new opportunities in the preparation of novel composite materials. Conductive polymers have been investigated for use as the electrode materials for a number of applications including rechargeable batteries, electrochemical sensors etc. Originality/value: Using the electropolymerization and electrodeposition processes in preparation of the composites. The analysis of structure and surface of the electrodeposited Ni-Mo alloys with different polymers.
