Dry film lubricants, alternatively known as solid film lubricants, are lubricating substances that are used to reduce friction between two sliding surfaces. Some of the popular dry film lubricants are graphite, molybdenum disulfide (MoS2), tungsten disulfide (WS2), and PTFE. They form a tough coating over the part and inhibit corrosion. This post discusses properties, applications, methods of application, and conditions in which these film lubricants are applied.
