Description
Известно керамическое покрытие дл заЩиты титана и его снлавов от газовой коррозии до те.гшературы 850°С, включающее В2Оз, SiO2, АЬОз и ZrOz.A ceramic coating is known for the protection of titanium and its corrosion from gas corrosion to a temperature of 850 ° C, including B2O3, SiO2, ABO3 and ZrOz.
Предложенное нокрытне имеет более высокие темнературы начала разм гчени и механическую прочность. Это достигаетс те-м, что оно содержит указанные компоненты в следуюндем соотношении (вес. %):The proposed product has higher temneuristics of softening onset and mechanical strength. This is achieved by the fact that it contains these components in the following ratio (wt.%):
В2Оз25-35B2Oz25-35

В качестве сырьевых материалов используют кварцевый песок, борную кислоту, глинозем , карбонат кальци (мел), окислы циркони и ниоби , которые смешивают в необходимых пропорци х и полученную шихту вар т при температуре 1400°С в течение 2 час в стекловаренной печи, после чего расплав гранулируют в воду, а гранул т измельчают G шаровых мельницах.The raw materials used are quartz sand, boric acid, alumina, calcium carbonate (chalk), oxides of zirconium and niobium, which are mixed in the required proportions and the resulting mixture is cooked at a temperature of 1400 ° C for 2 hours in a glass melting furnace, after which the melt is granulated into water, and the granulate is ground into G ball mills.
Нанос т эмаль на титановые детали известными в технологии эмалировани методами - окунанием в шликер, пульверизацией шликера , электрофорезом и др.Enamel enamel on titanium parts known in the technology of enameling methods - dipping in the slip, spray spraying, electrophoresis, etc.
Закрепленне покрыти производ т обжигом при температуре 950-1000°С в течение 10-20 ЛИН.The coating is fixed by firing at a temperature of 950-1000 ° C for 10-20 LIN.
Покрытие, состав которого следующий, вес. %: SiO2 15, BsOg 30, СаО 20, АЬО., 20, Zr02 10, NbjOs 5, имеет хорошие прочностные характеристики.Coverage, the composition of which is next, weight. %: SiO2 15, BsOg 30, CaO 20, ABO., 20, Zr02 10, NbjOs 5, has good strength characteristics.
В табл. 1 приведены данные испытани покрытий на удар пр« толщине 0,1 мм.In tab. 1 shows the test data on impact coatings with a thickness of 0.1 mm.
