Abstract—Glass-ceramic coatings on nickel and its alloys are produced from organic–inorganic hybrids by the
sol–gel method. The coatings are applied using sol–gel systems composed of tetraethoxysilane (inorganic
dopant), as well as of finely dispersed oxide and ultradispersed hybrid fillers. Acrylic and methacrylic acid
derivatives are taken as organic modifiers. Oligocarbonate dimethacrylate–substituted tetranuclear titanium
oxide clusters are used as the ultradispersed hybrid filler. The influence of the organic modifiers and ultradis-
persed hybrid fillers on the physicochemical processes occurring in the sol–gel systems and on the electrical
parameters of the coatings are experimentally studied, and the data obtained are analyzed.
