In this paper, an environmentally friendly electroplating process of amorphous Ni-P+TiO2+Ti coatings was developed. Co-deposition of inert or/and metallic powder particles in an amorphous nickel matrix enables the production of a large range of materials with unique properties. Composite Ni-P+TiO2+Ti coatings were prepared by simultaneous electrodeposition of nickel with titanium dioxide and titanium powder from a solution in which TiO2 and Ti micro-particles were suspended by stirring. The electrodeposition was carried out using a rotating disk electrode on a steel substrate under galvanostatic conditions at room temperature. Obtained coatings exhibit a structure of Ni-P matrix in which the crystalline TiO2 and Ti are embedded. Using AES method, the presence of the non-stoichiometric oxide, Ti10O19, and intermetallic compounds, NiTi, formed during the electrodeposition, were additionally observed on the Ni-P+TiO2+Ti coating surface. Present studies on examination of the effects of the variation of electrodeposition conditions has produced some understanding of Ni-P+TiO2+Ti coatings electrodeposition mechanism.
