Description
процесс в обычной печной среде при длительных высокотемпературных выдержках. Взаимодействие же фтористого натри с активными компонентами смеси ускор ет процессы адсорбции атомов бора и марганца на стальной поверхности, а следовательно , увеличивает скорость насыщени .process in a conventional furnace environment with long high-temperature exposures. The interaction of sodium fluoride with the active components of the mixture accelerates the processes of adsorption of boron and manganese atoms on the steel surface, and, consequently, increases the saturation rate.
При насыщении сталей из предлагаемой смеси диффузионные слои состо т из боридов железа, легированных марганцем.At saturation of the steels from the proposed mixture, the diffusion layers consist of iron borides doped with manganese.
Пример. Провод т боромарганцирование в обмазках образцов из стали 45 размерами 20X20x20 мм. Обмазку готов т смешиванием порошковых компонентов предлагаемой смеси (размер фракции 0,1 - 0,4 мм с гидролизованным этилсиликатом и нанос т толщиной 4-5 мм на образцы. После сушки в течение 10-20 мин при комнатной температуре на воздухе образцы помещают в электропечь, нагретую до 900°С и выдерживают 4 ч.Example. Boro-manganization is carried out in plasters of specimens of steel 45 with dimensions of 20 x 20 x 20 mm. The coating is prepared by mixing the powder components of the proposed mixture (fraction size 0.1-0.4 mm with hydrolyzed ethyl silicate and applied 4-5 mm thick to the samples. After drying for 10-20 minutes at room temperature in air, the samples are placed in an electric furnace heated to 900 ° C and incubated for 4 hours
Компоненты дл приготовлени смеси примен лись в виде технического карбида бора (ГОСТ 3647-71 и 5744-74), фтористого натри марки «Ч ГОСТ 4463-66, марганца порошкообразного, колчеданного огарка (отходы серно-кислотного производства ). В соответствии с ТУ 6-08-232-72 в состав колчедаиного огарка вход т следующие компоненты, мае. %: РезОз 70-75, SiO 10-13, АЬОз 5-8, прочие составл ющие до 100.The components for the preparation of the mixture were used in the form of technical boron carbide (GOST 3647-71 and 5744-74), sodium fluoride of the brand “CH GOST 4463-66, powdered manganese, pyrite calcine (waste sulfur-acid production). In accordance with Specification 6-08-232-72, the following components are included in the pyritic cinder, May. %: ResOZ 70-75, SiO 10-13, ABOz 5-8, other components up to 100.
Результаты диффузионного насыщени стали 45 при температуре 900°С в течение 4 ч представлены в таблице.The results of the diffusion saturation of steel 45 at a temperature of 900 ° C for 4 hours are presented in the table.
