Metal Sulfides - an overview | ScienceDirect Topics

Structure is related to the ability to lubrie and the oxide formation is related to the change from a soft material to a harder one. The true sulfide lubricant is the famous MoS 2, which forms layers with an interplanar distance of 3.49 Å and can lubrie until is transformed to MoO 3 in air above 500 °C. The sliding properties of MoS 2 are due to the weak interactions between the sulfur
