Description
Изобретение относитс к области машиностроени и может быть использовано дл защиты различных металлических деталей от газовой коррозии и воздействи агрессивных сред при повышенных температурах.The invention relates to the field of mechanical engineering and can be used to protect various metal parts from gas corrosion and exposure to corrosive media at elevated temperatures.
Известна эмаль, включаюн1а SiO2, Na2O, ВгОз, КгО, ВаО, NigOs, , CaO, АЬОз, МпаОз и А1.Enamel is known, including SiO2, Na2O, BrO3, CrO, BaO, NigOs, CaO, HOC3, MpaO3 and A1.
Цель изо-бретени - повысить жаростойкость и химическую устойчивость эмалевого покрыти .The goal of the invention is to increase the heat resistance and chemical resistance of the enamel coating.
Достигаетс это тем, что эмаль содержит следующие ком:поненты (в вес. %):This is achieved by the fact that the enamel contains the following materials: (in wt.%):

Предлагаемый состав тлав т при температуре 1300-1350°С в течение 40-50 мин. Полученный расплав гранулируют, гранул т высушивают при температуре 110°С и совместно с 4% Часов-Ярской глиной и 1-4,8% металлического алюмини измельчают по сухому способу.The proposed composition of the melt at a temperature of 1300-1350 ° C for 40-50 minutes. The melt obtained is granulated, the granulated material is dried at a temperature of 110 ° C and, together with 4% Chasov-Yarskaya clay and 1-4.8% of aluminum metal, is ground by the dry method.
Полученный шликер нанос т на металлическую поверхность, подготовленную любым из известных в технологии эмалировани способом .The resulting slip is applied to a metal surface prepared by any method known in the enamel process.
Обжиг ведут в окислительной атмосфере при температуре 900-920°С. Состав нанос т на подготовленную металлическую поверхность без грунтового подсло . Толщина обожженного сло (при однослойном эмалировании достигает 0,15-0,2 мм.Firing is carried out in an oxidizing atmosphere at a temperature of 900-920 ° C. The composition is applied to the prepared metal surface without a base coat. The thickness of the sintered layer (with single-layer enameling reaches 0.15-0.2 mm.
