Abstract

The effect of the components of chemico-catalytic reduction solutions on the formation rate, composition, and structure characteristics of Ni-Mo-B-alloy coatings is studied. The chemical state of elements and the composition of the surface and bulk layers of the coating containing 11 to 22 wt % of molybdenum and 1.0 wt % of boron are studied using XPS combined with layer-by-layer profile analysis. The alloys have crystalline nanostructure stable at temperatures of up to 500°C. Molybdenum is incorporated into the coatings preferably in its completely reduced form, as a supersaturated solid solution in the nickel matrix. Yet at the same time, the deposits absorb a substantial amount of the absorbed intermediate products of the molybdate reduction to Mo(IV).
