process of doping of used brushs of coal in electric, electric doped brushs of coal and motor engines with

NOVELTY – The method involves predicting motors electrical with carbon hydrogenated brushes doped with sulphur, having slippery anti-adhesive surfaces, which work efficiently if immersed in chemically aggressive environment. The hydrogenation and sulphurization method involves treating with brushes or pieces of carbon. USE – Used for electric motors. ADVANTAGE – The hydrogenation and sulphurization method involves treating brushes or pieces from carbon, and hence ensures low coefficient of friction in surfaces, elevated useful life. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are also included for the following: (1) carbon doped brushes (2) an electric motor doped with carbon brushes.
