Abstract:
Coating systems which provide corrosion resistance and, optionally, lubrication, for threaded connections are disclosed. The compositions comprise a first coating composition 200 comprising polymer matrices of polyimides or epoxies which are modified with small amounts of a fluorine containing polymer. Also present in the coating compositions are corrosion inhibiting agents and inorganic particles having a mean diameter of between approximately 10 nm and 10 [mu]m. Solid lubricants, which may include at least one of PTFE, HDPE, Graphite, and MoS2, are optionally added to provide the first coating with a low coefficient of friction. The coating systems may further comprise a second coating composition 202, comprising a solid lubricant dispersed within an epoxy resin and a solvent.; The first and second coating compositions 200, 202 are deposited on at least a portion of at least one of the pin and box members 100, 104 of the threaded connections
