FIELD: machine building.
SUBSTANCE: pipe screw joint consists of elements with inner and outer thread with their contact surfaces provided with thin coating tightly adhered to the base, said coating including solid-body matrix including dispersion of particles of one of the components: solid lubricant, corrosion inhibitor and surfactant, Solid-body matrix comprises at least one thermoset polymer and structure-forming agent. Element coating solid-body matrix with outer or inner thread structure-forming agent contains compounds of aromatic series while that of the other element contains aliphatic series compounds as structure-forming agent.
EFFECT: reliable joint under various operating conditions, higher wear resistance, high adhesion and low friction properties.
