Lubrication - an overview ScienceDirect Topics

Lubrication is a process which reduces the friction and wear between two moving solid surfaces with a film of solid,liquid or gaseous material without causing any damage to the surfaces.Both friction and abrasion are very complex processes,which depend on bulk and surface properties of the material.Many dynamic systems are lubricated by fluids of various kinds.Krytox PFPE Oils Greases TMC Industries,Inc.Krytox greases,using the most advanced lubricant formulated from space-age fluoropolymer technology are created by thickening synthetic perfluoropolyether (PFPE) base oils with micro-fine polytetrafluoroethylene (PTFE) powder,creating a white,nontoxic grease that provides excellent lubrication in demanding applications.The PTFE thickener forms a barrier that holds the base oil at Krytox PFPE Oils Greases TMC Industries,Inc.Krytox greases,using the most advanced lubricant formulated from space-age fluoropolymer technology are created by thickening synthetic perfluoropolyether (PFPE) base oils with micro-fine polytetrafluoroethylene (PTFE) powder,creating a white,nontoxic grease that provides excellent lubrication in demanding applications.The PTFE thickener forms a barrier that holds the base oil at
