What Does Corrosion Inhibiting Dry Film Lubricant Mean?
A corrosion inhibiting dry film lubricant, also called a corrosion inhibiting solid lubricant, is a chemical substance that is applied to the surface of another material or substrate in order to prevent corrosion or reduce the corrosion rate, and also to reduce the amount of friction that will be present when it is brought into contact with another surface.
Corrosionpedia Explains Corrosion Inhibiting Dry Film Lubricant
There are several types of corrosion inhibiting dry film (solid) lubricants available for use. One of the most common is polytetrafluoroethylene (PTFE), which is a polymer that is one of the best for reducing friction. Since it is non-metallic, it also leaves a coating that allows the base material to resist corrosion if applied correctly. Xylan, Teflon, graphite, molybdenum disulfide, fluorinated ethylene propylene, tungsten disulfide, antimony oxide, indium and boron nitride are some other types of dry film lubricants.
Corrosion inhibiting dry film lubricants are used in many different situations. Pistons are often coated with these coatings to reduce their friction coefficient with the cylinder wall with which they are in contact. Certain types of dry film lubricants are well-suited to be used in high heat environments such as electrical wire coatings. Other types can resist chemically aggressive environments; they lend themselves well to machinery commonly found in industries such as oil and gas.
