Abstract

AbstractThis work presents detail about lubrication, different types of lubrication, tribological properties such as friction and wear, the composition of lubricants, and the impact of lubricants on the environment. Further, it covers types of the lubrication system, choice of lubricants, properties, and applications of nano particles-based lubrication in oil mediums. It also explains the properties of grease and its suitable applications, particle-based lubrication such as graphene, molybdenum disulfide, boron nitride, boric acid, tungsten disulfide. Nanocomposite-based lubrication properties of epoxy-graphene-molybdenum disulfide (MoS2) under dry sliding contact are discussed in detail. Oil properties and their use, different oils, their viscosity, influencing parameters affecting the oil viscosity, viscosity and temperature relationship, methods to measure viscosity, and basics of absolute and kinematic viscosity are discussed. Significant rail components such as Elastic Rail Clips (ERC), Sealing linear, Switch Expansion Joint (SEJ) for effective lubrication methods are presented.KeywordsFrictionWearLubricationNanoparticles
