Изобретение относитс  к области термической обработки металлов и сплавов, в частности к термообработке деталей в вакууме.The invention relates to the field of heat treatment of metals and alloys, in particular to the heat treatment of parts in vacuum.

Известен способ обработки металлов и снлавов, по которому металл подвергают нагреву в вакууме с разрежением от 10 до 10 мм рт. ст. при температуре, равной 0,4- 0,8 т. пл.There is a method of processing metals and metals, according to which the metal is heated in vacuum with a vacuum of 10 to 10 mm Hg. Art. at a temperature of 0.4- 0.8 t. pl.

Целью изобретени   вл етс  ловышение контактной выносливости, надежности и долговечности деталей, прошедших механическую и термическую обработку.The aim of the invention is to improve contact endurance, reliability and durability of parts that have undergone mechanical and heat treatment.

Эта цель достигаетс  тем, что нагрев в вакууме деталей производ т до температуры отпуска.This goal is achieved by the fact that the parts are heated in vacuum to the tempering temperature.

Способ осушествл етс  следуюш,им образом .The method is carried out in the following manner.

Детали, прошедшие механическую и термическую обработку, помешают в нагревательную печь вакуумной камеры, котора  состоит из двух труб: большого и малого диаметра. Труба большого диаметра служит нагревателем и отпускной камерой, в которую загружаютс  издели . Труба м.алого диаметра-установлена внутри Отрубы большого:дуаме;гра. При пропускании тока :ПО.тр-убе.-г.малого -диа-, метра вокруг нее образуетс  .магнитное-поле, в сферу действи  которого и попадаот издели .Parts that have undergone mechanical and heat treatment are placed in a heating furnace of a vacuum chamber, which consists of two pipes: a large and a small diameter. The large-diameter pipe serves as a heater and a tempering chamber into which the products are loaded. The pipe of small diameter is installed inside. Cuts large: duame; gra. When a current is passed: PO.tr-ube-g small -dia-, a meter forms a magnetic field around it, into the sphere of action of which the product falls.

Нагрев производ т при температурах от 100 до 550°С в зависимости от .марки стали, при разрежении 10- - Ю- мм рт. ст., в течение 24-100 час. При этом происходит разложение поверхностных окислов, нитридов, оксидов, сульфидов, отвод иоиов водорода, кислорода, азота из локальных скоплений и уменьшение напр жепий в поверхностном Союе. Кроме того, в резу.г ьтате миграции газовых ионов и атомов металла интенсивно идет процесс удалени  микротрещин, пор и нолостей, что в значительной мере повышает прочность и пластичность поверхностного сло  металла.Heating is carried out at temperatures ranging from 100 to 550 ° C, depending on the steel grade, at a negative pressure of 10–10 mm Hg. Art., within 24-100 hours. In this case, decomposition of surface oxides, nitrides, oxides, sulfides, removal of ions of hydrogen, oxygen, and nitrogen from local accumulations and reduction of pressure in surface Soya occurs. In addition, as a result of the migration of gas ions and metal atoms, the process of removing microcracks, pores and tins is intensively proceeding, which greatly increases the strength and ductility of the surface layer of the metal.

Обработка предлагаемым способом позвол ет повысить прочность и долговечность таких деталей, например, подишпники.Processing the proposed method allows to increase the strength and durability of such parts, for example, podshitniki.
