Description
Изобретение относитс к покрытию, предназначенному дл защиты жаропрочных сплавов от высокотемпературной газовой коррозии при нагреве заготовок перед обработкой давлением .This invention relates to a coating designed to protect high-temperature alloys from high-temperature gas corrosion when heating billets prior to pressure treatment.
Известное покрытие, включающее SiOo, АЦОз, В2Оз, СаО, NagO, не служит надежной защитой при температуре 1200°С и .выдержке до 12 час.The known coating, including SiOo, ACOZ, B2O3, CaO, NagO, does not serve as reliable protection at a temperature of 1200 ° C and an exposure to 12 hours.
Предлагаемое стеклоВИДное покрытие отличаетс от из-вестного тем, что оно содержит указанные компоненты е следующих соотнощени х (вес. %) SiO 50-54; 14-15; ВаОз 10-15; СаО 16-17; NasO 0,5-2.The proposed glass-like coating differs from that known in that it contains these components in the following ratios (wt.%) SiO 50-54; 14-15; VAOZ 10-15; CaO 16-17; NasO 0.5-2.
Покрытие также может содержать MgO до 4%.The coating may also contain MgO up to 4%.
Дл .получени такого покрыти в качестве исходного сырь использую г кварцевый песок , глинозе м, борную кислоту, углекислый кальций, углекислый магний, соду. Плав т щихту ъ шамотных тигл х при температуре 1500-1550°С.-Стекломассу .выливают в воду.To obtain such a coating, we use g quartz sand, alumina, boric acid, calcium carbonate, magnesium carbonate, soda as a raw material. The melting point of fireclay crucibles at a temperature of 1500–1550 ° C. Glass mass is poured into water.
и полученные гранулы высущивают, измельчают до тонины 20-70 мк. Стекольный порошок смешивают с 2 .вес. ч. бентонита и 40 вес. ч. Боды. Полученный шликер нанос т .на холодную обезжиренную заготовку, на которой при нагрева.нии в результате оплавлени образуетс сплошной газонепроницаемый слой толщиной 70-150 мк.and the resulting granules are dried, ground to a fineness of 20-70 microns. Glass powder is mixed with 2. weight. including bentonite and 40 wt. h. body. The resulting slip is applied to a cold, skimmed billet, on which, when heated, as a result of melting, a continuous gas-tight layer of 70-150 microns is formed.
