摘要: A solid lubricating coating formed on a contact surface of a threaded joint for pipes has a matrix of a lubricating oil-containing polymer. The lubricating oil-containing polymer has either a uniform composition or a gradient composition in which the concentration of lubricating oil decreases towards the contact surface and in which there is substantially no lubricating oil in the vicinity of the contact surface.
