METHOD OF ELECTROLYTIC PRECIPITATION OF IRON-MOLYBDENUM DISULFIDE COATING Russian patent published in 2015 - IPC C25D15/00

Abstract RU 2537686 C1

FIELD: chemistry.

SUBSTANCE: method includes precipitation from electrolyte, containing, kg/m³: ferrous sulfate 400-600, molybdenum disulfide 100-200, hydrochloric acid 0.5-1.5, on asymmetric alternating current with asymmetry coefficient β=1.2-6.0 and cathode density 20-80 A/dm² with mechanical mixing of electrolyte with temperature 20-40°C and acidity pH 0.8-1.0.

EFFECT: increase of process productivity due to application of asymmetric alternating current and increase of coating wear resistance due to increase of composite component of molybdenum disulfide in coating.
