Two-dimensional (2D) layered molybdenum disulfide (MoS 2 ) has intriguing physical, mechanical, optical, and semi-conducting properties and has the potential to be used in a variety of applications, such as sensors, semi-conductor devices, energy storage/conversion devices, etc. Due to its superior lubricating capabilities resulting from the easy shearing of its lamellar structure, MoS 2 has traditionally been used as a solid lubricant and wear-resistant coating over metallic substrates. Unfortunately, its high susceptibility to corrosion and oxidation restricts its use in moist and humid environments. Oxidation profoundly affects the frictional, mechanical, semi-conducting, and optical properties of MoS 2 . This article extensively reviews the current state of knowledge on the corrosion and surface oxidation mechanism in MoS 2 and MoS 2 -based coatings. Besides, the effect of oxidation on the frictional properties of MoS 2 is also discussed. Several experiments undertaken to tailor the corrosion and oxidation properties of MoS 2 -based coatings to prompt their usage under humid and moist conditions are also comprehensively reviewed here. Recent employment of MoS 2 as a corrosion protective filler in organic coatings is also briefly discussed. This review discusses the corrosion and oxidation properties of MoS 2 and MoS 2 based coatings, their effect on the tribological properties of MoS 2 , and the recent progress in tailoring the corrosion resistance properties of MoS 2 based coatings.
