Изобретение относитс к применению контролируемых атмосфер и может использоватьс с целью предотвращени водородного охрупчивани металла при химико-термической обработке и светлом отжиге деталей машин.The invention relates to the use of controlled atmospheres and can be used to prevent hydrogen embrittlement of a metal during chemical heat treatment and light annealing of machine parts.
Известен способ термической обработки металла в контролируемой атмосфере с содержанием водорода 20-60% на всем прот жении обработки.A known method of heat treatment of a metal in a controlled atmosphere with a hydrogen content of 20-60% throughout the treatment.
Дл устранени водородной хрункости металла производ т дополнительную обработку в нейтральной атмосфере с содержанием водорода не более 2%, нри этом ранее поглощенный металлом водород десорбирует из металла .To eliminate the hydrogen crushiness of the metal, an additional treatment is carried out in a neutral atmosphere with a hydrogen content of not more than 2%. In this case, the hydrogen previously absorbed by the metal is desorbed from the metal.
Способ исключени водородной хрупкости металла осуществл етс путем полной замены в 1нвчи заключительной стадии лроцесса термической обработки (до сн1 жени температуры ) технологической атмосферы с высоким содержанием водорода на нейтральную атмосферу с содержанием водорода не более 2%. В лабораторных услови х образцы из сталл 18ХГТ подвергали сквозной химико-термической обра:бота е при 920° С и 870° С в атмосфере эндогаза (40% Н2, 20% СО и ост. Ng) по обычной технологии и но предлагаемой.The method of eliminating the hydrogen embrittlement of a metal is carried out by completely replacing in the final stage of the heat treatment process (before the temperature is reduced) a high hydrogen content process atmosphere with a neutral atmosphere with a hydrogen content not exceeding 2%. Under laboratory conditions, samples from 18HGT steels were subjected to a through chemical and thermal treatment: bot e at 920 ° C and 870 ° C in the atmosphere of endogas (40% H2, 20% CO and OST) according to the usual technology and proposed.
По данному способу получены средние показатели в зкости стали на 10-25% выще, чем по обычной технологии, что хара.ктеризует соответствующее снижение водородного охрупчивани металла.In this method, the average viscosity of steel is obtained by 10–25% higher than by conventional technology, which characterizes a corresponding decrease in hydrogen embrittlement of the metal.
