Изобретение относитс к стеклоэмалевым покрыти м, используемым дл защиты жаропрочных сталей от окислени при нагреве.The invention relates to glass enamel coatings used to protect heat resistant steels from oxidation when heated.
Известна эмаль, включающа SiOa, ВзОз, ВаО, СаО, MgO.Enamel is known, including SiOa, BocO3, BaO, CaO, MgO.
Цель изобретени - улучшить защиту от окислени при высоких температурах.The purpose of the invention is to improve the protection against oxidation at high temperatures.
Достигаетс это тем, что эмаль содержит указанные компоненты в следующем количе.стве , вес. %:This is achieved by the fact that the enamel contains these components in the following quantity, weight. %:
SiOa 31,50-42,75; BaOg 23,75-131,50; ВаО 14,,50; СаО 3,60-9,50; MgO 9,76- 10,9.SiOa 31.50-42.75; BaOg 23.75-131.50; BAO 14,, 50; CaO 3.60-9.50; MgO 9.76-10.9.
(При М е р. Предлагаема эмаль содержит следующие компоненты, вес. %: SiOg 36,0; ВгОз 27,0; ВаО 18,0; СаО 6,3; MgO 10,9.(When Mer. The proposed enamel contains the following components, wt.%: SiOg 36.0; BrOz 27.0; BaO 18.0; CaO 6.3; MgO 10.9.
Описываема эмаль обладает следующими свойствами:The enamel described has the following properties:
рабоча температура, °С 1000-1160operating temperature, ° C 1000-1160
врем выдержки, час0,5-2holding time, hours 0.5-2
краевой угол смачивани при рабочих температурах , °С20. При нагреве жаропрочных сталей с описываемым покрытием до 1160°С в течение 1 час отсутствует окисление стальной поверхности и потери металла в окалину.wetting angle at operating temperatures, ° C20. When heated, heat-resistant steels with the described coating to 1160 ° C for 1 hour there is no oxidation of the steel surface and metal loss into scale.
