ABSTRACT:
The object of the present invention is to provide a protective metal-ceramic film having a heterogeneous structure and possessing higher density, wear resistance, a high adhesion to a friction surface and a friction coefficient after running in not higher than 0.03-0.07.The above object is solved by providing a plating concentrate comprising a powdered metallic filler, surfactants, oil soluble dialkyl dithiophosphoric acid metal salts and a basic oil, a mineral filler based on silicates and cyclohexanol at the following ratio of components in % by weight:a powdered metallic filler0.05-20.0surfactants 0.5-11.0dialkyl dithiophosphoric acid metal salts 1.0-45.0a mineral filler based on silicates 1.2-20.0cyclohexanol0.05-2.0 A mineral filler based on silicates comprises natural minerals from a series of layered hydro silicates such as serpentinite and/or chlorite.Salts of zinc and/or tin and/or molybdenum and/or aluminum and/or copper and/or cadmium are used as dialkyl dithiophosphoric acid metal salts.
