Claims (1)

Способ относится к химико-термической обработке стальных деталей, в частности нефтегазодобывающего оборудования, и может быть использован для повышения стойкости стальных деталей против усталостного разрушения, коррозии и износа в топливно-энергетической, металлургической и машиностроительной отраслях промышленности при металлообработке. Способ включает подготовку рабочей поверхности деталей, химико-термическую обработку и охлаждение. Новым является то, что подготовку рабочей поверхности деталей перед химико-термической обработкой ведут дробеструйной обработкой, а охлаждение после термообработки совмещают с процессом оксидирования и осуществляют в воде с температурой выдержки химико-термической обработки.The method relates to chemical-heat treatment of steel parts, in particular oil and gas production equipment, and can be used to increase the resistance of steel parts against fatigue fracture, corrosion and wear in the fuel and energy, metallurgical and engineering industries during metalworking. The method includes the preparation of the working surface of the parts, chemical heat treatment and cooling. New is the fact that the preparation of the working surface of the parts before the chemical heat treatment is carried out by shot blasting, and the cooling after the heat treatment is combined with the oxidation process and is carried out in water with the holding temperature of the chemical heat treatment.
