Description
Изобретение относитс к составу покрыти дл защиты металлов, наносимого на последние методами плазменного или газоплазменного напылени .The invention relates to a coating composition for the protection of metals applied to the latter by plasma or gas plasma spraying methods.
Известно керамическое покрытие дл защиты металлов на основе А12Оз с добавкой liOz, имеющее значительную пористость и не обеспечивающее надежной защиты металла от воздействи жидких и газообразных агрессивных сред.A ceramic coating is known for the protection of metals on the basis of A12Oz with the addition of liOz, which has considerable porosity and does not provide reliable protection of the metal from the action of liquid and gaseous corrosive media.
Описываемое покрытие не имеет этих недостатков и отличаетс от известного тем, что оно содержит указанные компоненты в следующих количествах (в вес. %):The described coating does not have these disadvantages and differs from the known one in that it contains the indicated components in the following amounts (in wt.%):
АЬОз80 -90ABOS80 -90
ТЮг5 -15Tug5 -15
И, кроме того,And besides,
VaOs0,5-10VaOs0,5-10
Дл получени защитного покрыти смесь порошков исходных компонентов прокаливаютTo obtain a protective coating, the mixture of powders of the initial components is calcined.
нри температуре 1000-1700 0, полученный ма териал измельчают и отсеивают фракцию, необходимую дл напылени (40-70 кмк).At a temperature of 1000-1700 0, the resulting material is crushed and the fraction necessary for spraying is screened out (40-70 km / s).
Эта композици после напылени на поверхность металла образует плотное покрытие, имеющее высокую адгезию к металлу.This composition, after deposition on the metal surface, forms a dense coating having high adhesion to the metal.
