Friction and wear are not intrinsic properties of materials; they vary depending on extrinsic conditions. Humidity is one of such extrinsic parameters. This paper reviews the effects of humidity on friction and wear of various types of materials, which include graphite and graphene, diamond-like carbon (DLC) films, ultrananocrystalline diamond (UNCD), transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN), boric acid, silicon, silicon oxide, silicates, advanced ceramics, and metals. Details of underlying mechanisms governing tribochemical reactions between the tribo-materials and the adsorbed water molecules are also reviewed. View this paper.
