METHOD OF STEEL PARTS SULFOCEMENTERING Russian patent published in 2018 - IPC B23H1/00 B23H9/00

Abstract RU 2663799 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to electrophysical and electrochemical processing, in particular to electroerosion alloying (EEA) and can be used for surface treatment of heat-treated parts. Method of sulfoncemetering the surface of steel part includes electroerosive alloying of surface of steel part with graphite electrode immediately before which sulfur paste and/or sulfuric ointment is applied to surface of said part, and electroerosion alloying is carried out at discharge energy W_p=0.13–3.4 J. In sulfuric paste and/or sulfuric ointment, colloidal sulfur is also added.

EFFECT: invention provides increased lapping and increased wear resistance of steel parts.
