Description

1(54) СПОСОБ ТЕРМИЧЕСКОЙ ОБРАБОТКИ1 (54) METHOD OF THERMAL TREATMENT

ДИСПЕРСИОННО-ТВЕРДЕКЗДИХ СПЛАЮВDISPERSION-HARDNESSES ALLOY

стабилизирующий отпуск в вакууме при температуре 350 С в течение 12 час.stabilizing tempering in vacuum at a temperature of 350 ° C for 12 hours.

В таблице приведены марки сплавов, .режимы термической обработки и даиные по величине иэиосостойкости.The table shows the grades of alloys, heat treatment modes and the largest in terms of resistance and heat resistance.

Как видно из таблицы, предлагаемый способ термической обработки повышает износостойкость сплава 40ХНЮ-ВИ , котора  становитс  выпе износостойкости широко примен емого дл  подшипников качени  сплава 11Х18М,As can be seen from the table, the proposed heat treatment method increases the wear resistance of the alloy 40ХНЮ-ВИ, which becomes wear resistance widely used for rolling bearings of the alloy 11Х18М,
