Description

в таблице приведены примеры, поверхностно-активных веществ, подобранных этими методами, дл  введени  их в газообразные или жидкометаллические хладагенты при защите материалов в интервалеЛООО- 2000°С.The table lists examples of surfactants selected by these methods for introducing them into gaseous or liquid metal refrigerants when protecting materials in the range LOOO-2000 ° C.

При тепловой защите вдуврм эти поверхностно-айтивные вещества ввод тс  испарением , например, в азот, используемый как хладагент, подаваемый в пористый материал (открыта  пористость ) на основе окиси магни , ZrOs, ThO и Nb, Та, Mo, W,In the case of thermal protection of a vvrm, these surfactants are introduced by evaporation, for example, into nitrogen, used as a refrigerant supplied to the porous material (open porosity) based on magnesium oxide, ZrOs, ThO and Nb, Ta, Mo, W,

)хн6стно-акИ§ЮХТвё1цеств в два-п ть раз уменьшает интенсивность взаимодействи  хладагента с.материалом и стабилизирует . структуру .перового пространства , повЬ1ша  ресурс эйспАуатац и материала .     ) hn6stno-aksuhtvetstsevts two or five times reduces the intensity of the interaction of the refrigerant with the material and stabilizes. structure of perovoy space, the same resource eispAuatats and material.

Предлагаемый способ позвол ет повысить ресурс эксплуатации пористргб материала не менее чем в 2-3 раза. The proposed method allows to increase the service life of porous material of the material by at least 2-3 times.
