This paper presents results concerning the electrochemical deposition of Ni-TiO2 composite coatings, focusing on the influence of electrode potential, TiO2 concentration in the electrolyte, and the magnetohydrodynamic effect (MHD) on various deposition characteristics. A thermodynamic analysis preceded the electrochemical studies, and the electrokinetic potential of TiO2 particles was determined in the applied electrolyte. Analysis revealed that the coatings could contain up to 2.15 wt. pct of TiO2, with current efficiencies varying from 31.7 pct without magnetic field influence to 34.2 pct with a magnetic field. The magnetic field was shown to significantly affect the processes occurring at the electrode surface, with comparative studies indicating precipitation of nickel hydroxides and hydrides alongside hydrogen evolution reactions. Consequently, the coatings were characterized to assess their photoelectrochemical properties. This comprehensive investigation reflects the potential of optimizing Ni-TiO2 composite coatings for improved efficiency in solar energy conversion systems.
