The Ni–MoO
3
composite films exhibiting low coefficient of friction (∼0.05) were obtained by electrolytic co-deposition of nickel with MoO
3
microcrystals of layered structure synthesized via solvothermal method. It has been shown that the redox activity inherent in molybdenum trioxide ensures efficient overgrowing of the trapped MoO
