Description
Изобретение относитс к металлургии , в частносои к химико-термической обработке, а именно к совместному диффузионному насыщении) ниобием и кремнием изделий иа титана и его сплавов. Состав-может быть использован дл повышени износо-, жаро- и коррозион ной стойкости изделий из титана и его сплавов в машиностроительной, авиацио нной, судостроительной, химической и др. отрасл х промышленности . Известен состав дл ниобийсилийировани титановых сплавов из порошков окислов насыщающих элементов дл повышени ИЗНОСО-, жаро- и коррозион ной стойкости титановых сплавов 1}. Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту вл етс Состав дл ни . обийсилццировани изделий из титана и его сплавов, содержащий, мас.%; 10pC50Al2 (gOCK+SNb Oyil+eAIF . После насыщени в известном составе при 900°С за 4 ч формируютч диффузионные слои толщиной 40-60 мкм П23 Недостатком известного состава вл етс низка насыщающа способность при температурах до 900°С. Повышение же температуры насыщени дл увеличени насыщающей способности неприменимо дл многих изделий из титана и его сплавов, нагрев кото рых выше температуры полиморфного прекращени - ббО С) вызывает рост зерна в сплаве и резкое снижение механических свойств изделий. Цель изобретени - повышение насыщающей способности состава. Дл достижени указанной цели известный состав дл ниобийсилицировани изделий из титана и его сплавов ,. содержащий п тиокись ниоби , окись алюглини , кремнийсодержащее вещество и фтористый алюминий, дополнительно содержит порошок меди, порошок алюмини , а в качестве кремнийсодержащего вещества - двуокись кремни при следующем соотношении компонентов, мас,%: П тиокись ниоби 5-15 Двуокись кремни -20-30 , Порошок алюмини 20-30 Порошок меди 10-20 Фтористый алюминий 2-4 Окись алюмини Остальное Пример. Провод т насыщение титановых сплавов ВТ1-0, ОТ4 и ВТ14 при 850с в течение 4 ч в различных составах. Сравнительные данные по насыщающей способности предлагаемого и известного составов представлены в таблице. Из таблицы видно,.что насыщающа способность предлагаемого состава дл ниобийсилицировани титановых сплавовв 7-8 раз выше, чем из- . . вестного.The invention relates to metallurgy, in particular, to chemical and heat treatment, namely to the joint diffusion saturation of titanium and its alloys with niobium and silicon. The composition can be used to increase the wear, heat and corrosion resistance of products made of titanium and its alloys in the engineering, aircraft, shipbuilding, chemical and other industries of the industry. A known composition for niobium-plating titanium alloys from powders of oxides of saturating elements to increase the WEAR, heat and corrosion resistance of titanium alloys 1}. The closest to the proposed technical essence and the achieved effect is Composition for ni. blistering products made of titanium and its alloys, containing, in wt.%; 10pC50Al2 (gOCK + SNb Oyil + eAIF. After saturation in a known composition at 900 ° C for 4 hours, diffusion layers of 40-60 µm thick are formed. P23 The disadvantage of the known composition is low saturation ability at temperatures up to 900 ° C. Increasing the saturation temperature for an increase in saturability is not applicable to many products made of titanium and its alloys, the heating of which is higher than the polymorphic termination temperature (bbO C) causes grain growth in the alloy and a sharp decrease in the mechanical properties of the products. The purpose of the invention is to increase the saturability of the composition. In order to achieve this goal, a known composition for niobium silicating articles of titanium and its alloys,. containing niobium pentoxide, alumina oxide, silicon-containing substance and aluminum fluoride, additionally contains copper powder, aluminum powder, and silica as the silicon-containing substance in the following ratio, wt.%, niobium dioxide 5-15 Silicon dioxide -20- 30, Aluminum powder 20-30 Copper powder 10-20 Aluminum fluoride 2-4 Aluminum oxide Rest Example. Titanium alloys VT1-0, OT4 and VT14 are saturated at 850s for 4 hours in various compositions. Comparative data on the saturability of the proposed and known compositions are presented in the table. It can be seen from the table that the saturability of the proposed composition for the niobium-siliconization of titanium alloys is 7-8 times higher than that of i-. . well-known.
