Description
, 1. / Изобретение относитс к химикО термической обработке и может быть гфименено в качестве насыщающей сре ды дл диффузионного боросилйциро- ; вани стальных изделий. Известен ростав дл боросилицировани , содержащий следующие компонен ты, вес.« Карбид бора74,8 . Бура15,2 Кремний 5 Хлористый аммоний 5 1. Однако такой состав требует использовани дорогосто щей оснастки, не позвол ет проводитьзакалку непосредственно после химико-термической обработки и расходуетс большое количество насыщающей смеси. Известен также состав дл боросилицировани , содержащий следующие компоненты, вес.%: Борный ангидрид : Силикокальций 3,5 Фтористый алюминий Остальное 12 Окись алюмини Известный состав позвол ет проводить насыщение из порошков в герметических жаростойких контейнерах с использованием плавких затворов. Недостатками такого состава вл ютс относительно низка скорость формировани боросилицированных диф7 фузионных слоев, необходимость проводить насыщение из поретиков в герметических жаростойких контейнерах с использованием плавких затворов, расходуетс большое количество насыщающей смеси, затрудн етс термическа обработка после процесса химикотермической обработки. Целью изобретени вл етс проведение процесса насыщени в окйсли|Тельной среде и увеличение активнос ти насыщающей смеси. Поставленна цель достигаетс чем, что состав содержит в качестве боросодержащего вещества - карбид бора, в качестве кремнийсодержащих веществ перефилит и огарок и в качестве активатора - фтористый натрий при следующем соотношении компонентов, вес.%: Карбид бора45-60 Перефилит15-30 Огарок15-30. Фтористый натрий 3-10. В качестве св зующего дл обмазки используетс гидролизованный этилсиликат . , 1. / The invention relates to chemical heat treatment and may be formulated as a saturating medium for diffusive borosilution; vani steel products. A known composition for borosilization, containing the following components, by weight. Boron carbide 74.8. Bura 15,2 Silicon 5 Ammonium Chloride 5 1. However, such a composition requires the use of expensive tooling, does not allow quenching directly after the heat treatment, and consumes a large amount of saturating mixture. A borosilization composition is also known, containing the following components, wt%: Boric anhydride: Silicocalcium 3.5 Aluminum fluoride Remaining 12 Alumina The known composition allows saturation of powders in hermetic heat-resistant containers using fusible closures. The disadvantages of this composition are the relatively low rate of formation of borosilicated diffusion layers, the need to saturate the portions in hermetic heat-resistant containers using fusible closures, a large amount of saturating mixture is consumed, and heat treatment is difficult after the chemical-heat treatment process. The aim of the invention is to carry out the saturation process in oxygenation medium and increase the activity of the saturating mixture. The goal is achieved in that the composition contains boron carbide as a boron-containing substance, perefilite and calcine as silicon-containing substances, and sodium fluoride as an activator in the following ratio of components, wt.%: Boron carbide45-60 Perefilite15-30 Ogarok15-30. Sodium fluoride 3-10. Hydrolyzed ethyl silicate is used as a binder for coating.
