Research on the Tribological Property of Synthetic Multilayer MoS₂/FeS Film under Dry Condition

Abstract

In this paper, we adopted a novel method, namely, magnetron sputtering + low temperature ion sulfurizing composite technology to prepare synthetic MoS2/FeS multilayer film. The obtained film has a quite smooth surface with plenty of spherical particles. The friction tests were carried out on a ball-on-disc tester under dry condition. During the whole test, the friction coefficient of the MoS2/FeS multilayer film was always lower than that of the original 1045 steel and FeS film. In addition, the wear scar depth of the MoS2/FeS multilayer film was also low. It is undoubtedly that the synthetic MoS2/FeS multilayer film possesses excellent friction-reducing and wear-resisting behaviors.

Microstructure and Tribological Properties of Self-Lubricating FeS Coating Prepared by Chemical Bath Deposition Coating Technique

“…Depositing a solid lubricating coating on the gear surface is considered to be a simple and very effective approach to improve the wear resistance of materials. FeS is considered as an excellent solid lubricant because of its hexagonal structure, low shear strength, and high melting point [22,[30][31][32][33][34]. Moreover, the cost is very low, only about 1% that of MoS 2 coating which is also considered as a good solid lubricant for the gears [35,36].…”
