Abstract (en)

[origin: WO8203575A1] MoS2 is applied to medium to high carbon and stainless steels after surface voids have been produced in the material, as by a final annealing operation, but before a final cold working operation reduces the material to finished size. The latter operation embeds or includes the MoS2 into the material and thereby provides a superior lubricated steel for piston ring, shaft, valve stem, spring, stranded wire and the like applications. The technique involved may also employ corrosion inhibiting agents to increase resistance to corrosion of the steel as well as to improve its lubricity.
