High friction coefficient of contacting surfaces is one of essential problems in many industries, e.g. automotive, aerospace, home appliances, electronics, etc. It is almost impossible to perform lots of industrial processes without lubricating coatings known as solid film lubricants. On the other hand, some solid film lubricants are toxic and flammable which restricts their use considering health, environment and security. Solid fil lubricants are based on from solid systems used for reducing friction coefficient. Various materials have been used as solid film lubricants with different application methods. Solid film lubricants usually include one or two types of solid particle lubricants dispersed in binder diluted with a solvent to apply on a surface. This article provides are review on solid film lubricants and three main groups of them based on molybdenum sulfide, graphene and polytetrafluoroethylene.
