Description
Изобретение относитс к химико-термической обработке материалов.This invention relates to the chemical heat treatment of materials.
Известна среда дл вольфрамоалитироваии , содержаш.а порошкообразные компоненты в следующем соотношении, вес. %: Окись алюмини 30A known medium for tungsten-analytical, containing powdered components in the following ratio, weight. %: Aluminum oxide 30

Окись вольфрамаОстальноеTungsten OxideEverything Else
Недостатком этой среды вл етс длительность процесса насыщени (4 час при температуре 1100°С) и необходимость защитных средств при нагреве.The disadvantage of this environment is the duration of the saturation process (4 hours at a temperature of 1100 ° C) and the need for protective agents during heating.
Известна среда по технической сущности и достигаемому эффекту наиболее близка к предложенной.Known environment in technical essence and the achieved effect is closest to the proposed.
Целью изобретени вл етс интенсификаци процесса насыщени и ведение процесса в печной атмосфере.The aim of the invention is to intensify the saturation process and to conduct the process in a furnace atmosphere.
Эта цель достигаетс тем, что предложенна среда дополнительно содержит св зку, а в качестве порошкообразных компонентов - порошок вольфрама и алюминиевую пудруThis goal is achieved by the fact that the proposed medium additionally contains a binder, and as powder components - tungsten powder and aluminum powder.

Процесс насыщени осуществл ют шликерным методом. Дл приготовлени суспензии используют мелкодисперстный порошок вольфрама , алюминиевую пудру ПАП-2 (ГОСТThe saturation process is carried out using the slip method. To prepare the suspension, fine-tungsten powder, PAP-2 aluminum powder (GOST) are used.
5491-71), а в качестве св зки 10-40%-ный раствор цапонлака № 951 (ГОСТ 5236-50) в растворителе 646 (ГОСТ ).5491-71), and as a binder there is a 10-40% solution of zaponlak No. 951 (GOST 5236-50) in a solvent 646 (GOST).
На очищенный от загр знений образец нанос т суспензию в количестве 0,01-0,06 г/смSuspended in the amount of 0.01-0.06 g / cm is applied to the sample cleared from contamination.
и сушат в течение 10-40 мин при 150-200°С. Затем образец нагревают в печи при 950- 1050°С в течение 10-20 мин и охлаждают на воздухе или в воде. Оставщиес на образце продукты реакции смывают водой.and dried for 10-40 minutes at 150-200 ° C. Then the sample is heated in an oven at 950-1050 ° C for 10-20 minutes and cooled in air or in water. The reaction products left on the sample are washed off with water.
После насыщени в течение 20 мин при 1000°С на сплаве ВЖЛ12 получают диффузионные слои, свойства которых представлены в таблице (св зка 260 мл).After saturation for 20 minutes at 1000 ° C, diffusion layers are obtained on the VZHL12 alloy, the properties of which are presented in the table (coupling 260 ml).
