Description
(5) СОСТАВ ДЛЯ БОРОАЛИТИРОВАНИЯ СТАЛЬНЫХ (5) COMPOSITION FOR BOROBILEATING STEEL
II
Изобретение относитс к металлургии , в частности к химико-термической обработке, а именно к составам дл совместного насыщени бором и алюминием изделий из металлов и сплавов . Состав может быть использован дл повышени износостойкости деталей машин, инструмента и технологической оснастки в машиностроительной, металлургической, станГкостроительной и других отрасл х промышленности.The invention relates to metallurgy, in particular to chemical heat treatment, in particular to compositions for co-saturation of articles made of metals and alloys with boron and aluminum. The composition can be used to increase the wear resistance of machine parts, tools, and tooling in the engineering, metallurgical, stan- ging and other industries.
Известен состав дл бороалитировани , содержащий, мас.%: борный а н гидрид 10-15; алюми ний (порошок) фтористый натрий 0,5-2,0; окись алюмини остальное. Процесс бороалитировани сталей в этом составе осуществл етс при 850-1050°С в течение 5-6 ч. Так при бороалитировании при . в течение «ч сталей 5 и У8 формируютс диффузион-. ные .слои толщиной 55 и 50 мкм соответственно l J. ИЗДЕЛИЙA known composition for boron catalytic analysis, containing, in wt.%: Boric and n hydride, 10-15; aluminum (powder) sodium fluoride 0.5-2.0; alumina rest. The process of boronization of steels in this composition is carried out at 850–1050 ° C for 5–6 hours. So, when boronalyzing at. Diffusion- is formed within 5 hours of steel 5 and Y8. nye layers of 55 and 50 microns, respectively, l J. PRODUCTS
Недостатком состава вл етс его низка насыщающа способность.The disadvantage of the composition is its low saturation ability.
Наиболее близким к изобретению вл етс состав дл бороалитировани , содержащий, мас.%: окись бора , алюминий , фтороборат кали 5-15, окись алюмини остальное .The closest to the invention is a boron-catalytic composition containing, in wt%: boron oxide, aluminum, potassium fluoroborate 5-15, alumina the rest.
Однако так же как и у предыду цего состава его насыщающа способность недостаточно велика.However, as with the previous composition, its saturating capacity is not large enough.
Цель изобретени - повышение насышающей способности состава.The purpose of the invention is to increase the saturation of the composition.
Поставленна цель достигаетс путем использовани в составе дл JJ бороалитировани , содержащем окисьThe goal has been achieved by using an oxide containing
бора, порошок алюмини , окись алюмини .и фтороборат кали , дополнительно аммони сернокислого, имеющего формулу ( при следующем JQ соотношении компонентов, мас.%:boron, aluminum powder, alumina. and potassium fluoroborate, additionally ammonium sulfate, having the formula (with the following JQ ratio of components, wt.%:
Окись бора 20-25 : Порошок алюмини 20-25 Фтороборат кали 3-6 Аммоний сернокислый 2Окись алюмини Остальное Все материалы используютс в виде порошков. Пример. Провод т обработку при 900 С в течение f ч в различных по количеству вход щих компонентов составах. Сравнительные данные по насыщающей способности предлагаемого и известного составов представлены в таблице.Boron Oxide 20-25: Aluminum Powder 20-25 Potassium Fluoroborate 3-6 Ammonium Sulfate 2 Aluminum Oxide Else All materials are used in the form of powders. Example. The treatment is carried out at 900 ° C for f hours in various compositions according to the number of components. Comparative data on the saturability of the proposed and known compositions are presented in the table.
