The essence of this R&D work lies in saturation of the steel surface with boracium and sulphur in a fluid salt mixture at temperatures that are lower or equal to that of high-temperature tempering. This R&D work is destined for wear resistance increase of surface layer of carbon steels under conditions of solid lubrication.
The main advantages of the R&D work are in lack of any wear and tear for helical gears with gear accuracy grouped from 4 through 6, under conditions of solid lubricant ЛИТА-3, after 5,000 - 7,000 hours of operation. Lubrication is made once prior to commencement of continuous operation.
The R&D method has been used in full-scale industrial operation of gears of the motion-picture machines for 5 years and has shown no tear and wear.
