Abstract |
Composite Ni+Mo coatings were obtained by electrodeposition of Ni with Mo particles on a steel substrate from the nickel bath in which metallic powder was suspended by stirring. Deposition was conducted under galvanostatic conditions. Deposits were characterized by the presence of Mo microsize particles embedded into the nanocrystalline nickel matrix. The influence of metal powder amount in the bath, as well as deposition current density on the chemical composition of coatings was investigated. It was stated that the content of incorporated Mo increases with the increase in the amount of metal powder in the bath, and diminishes with the increase in deposition current density. The mechanism of metallic particles embedding was explained on the base of Ni2+ ions adsorption process. Incorporation of Mo powder into electrolytic nickel matrix causes an increase in the real surface area of deposits. |
