Sir please give me the importance tips of corrosion resistance gear box

Abstract


A gear box or the like adapted for prolonged effective use in a harsh and/or corrosive environment such as found in the chemical industry and are in which salt water is prevalent. Components of the gear box are provided with protective polymer coatings which are low friction and impervious to attack from the environment and materials used therein. Exterior surfaces of the housing are coated with a polymer that also withstands impact from foreign objects as exemplified by polyamides, epoxies and fluorocarbons with nylon being preferred. Other components such as the input shaft, bushings and the like are preferably coated with one or more layers of fluorocarbon polymers, with layers in contact with the component including a thermosettable binder component such as a phenolic. Certain coating thicknesses are most preferred.
