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 filler 0.05-20.0 surfactants  0.5-11.0 dialkyl dithiophosphoric acid metal salts  1.0-45.0 a mineral filler based on silicates  1.2-20.0 cyclohexanol 0.05-2.0 

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.

Claims

1. A plating concentrate comprising a powdered metallic filler, surfactants, oil soluble dialkyl dithiophosphoric acid metal salts and a basic oil, cyclohexanol and mineral filler which comprises:

a fiberglass, powdered quartz, natural minerals from the series of layered hydro silicates, at the following concentration of components in % by weight;

2. The plating concentrate according to claim 1, wherein serpentinite and/or chlorite are used as the layered hydro silicates.
