METHOD OF PROTECTION OF RAIL HEAD SIDE WEAR AND LUBING COMPOSITION TO THIS END Russian patent published in 2015 - IPC B61K3/00 C10M125/00 C10M159/04 

FIELD: transport.

SUBSTANCE: invention relates to railway transport. Proposed method consists in that lubricant composition based on organic binder is applied on rail head surface at track curved sections and pointwork zones. Said composition comprises solid lubricant as dispersed powder of serpentinite and combination of laminar and metal clad components as powder of graphite, molybdenum disulphide and powder of soft metal and/or alloys, i.e. aluminium, tin, zinc, copper and brass. In compliance with this process, said lubricant is used. Said lubricant comprises solid lubricant, said serpentinite. Note here that, additionally, this combination comprises the combination of powders of graphite, molybdenum disulphide and powder of soft metal and/or alloys at following ration of components, wt %: serpentinite - 5-20, graphite - 2-10, molybdenum disulphide - 2-10, powder of soft metal and/or alloys - 2-10, organic binder making the rest.

EFFECT: longer life of rails.
