Abstract
A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation layer, an interstitial adhesive layer, and a lubricating material layer. The base adhesive layer adheres to the device's surface thus enabling the coating to form a sealing liner. The intermediary insulation layer is positioned in between the base adhesive layer and the interstitial adhesive layer. As a result, the intermediary insulation layer prevents negative chemical interactions between the base adhesive layer and the interstitial adhesive layer. The lubricating material layer is super imposed onto the interstitial adhesive layer to provide a friction-reducing coating for the device's surface.
