Изобретение относитс к стекольной нромьишленности . Оно МОжет .примен тьс дл защиты металлов от высокотемнературной газовой коррозии.The invention relates to glass breaking. It can be used to protect metals from high-temperature gas corrosion.
Известно стеклокристаллическое покрытие дл стали, включающее SiO2, АЬОз, Li20, КгО и PaOs.A glass-ceramic coating for steel is known, including SiO2, ABOz, Li20, CgO and PaOs.
Цель изобретени - снизить температуру обжига и увеличить .коэффициент термического расширени .The purpose of the invention is to reduce the burning temperature and increase the coefficient of thermal expansion.
Это доствгаетс тем, что покрытие содержит указанные компоненты в следующих количествах (в&с. %):This is achieved in that the coating contains the indicated components in the following amounts (in & c.%):
