Chalcogenides are materials containing one or more chalcogen elements (e.g. S, Se or Te) as a substantial constituent. They are covalently bonded materials and, although they may be amorphous or crystalline, they are fundamentally semiconductors with a band gap typically of 1–3 eV, depending on composition
WFT uses burnishing and resin bonding of MoS2 coatings on to the steel substrates as thin films to enhance the life of moving components like bushes,bolts and nuts,screws,gears. Molybdenum di-Sulphide chemical has got an excellent embeddability property to steel substrate.
