Abstract
A coating which provides corrosion resistance, wear resistance, and, optionally, lubrication, for deposition on a threaded article is disclosed. The coating comprises a polymer matrix, such as a polyimide, which is modified with small amounts of a fluorine containing polymer modifier, as well as other compounds or additives to improve performance of the coating. Additionally, the coating can further comprise a solid lubricant or an anticorrosion compound dispersed within the polymer matrix.
