Description
Изобретение относитс к составу эмали, используемой дл защиты легированных сталей и сплавов от высокотемпературной газовой коррозии.This invention relates to an enamel composition used to protect alloy steels and alloys from high temperature gas corrosion.
Известна эмаль, включающа SiOa, ВаО,Known enamel, including SiOa, BaO,
ТЮ2.Tyu2.
Цель изобретени - улучщить сцепление покрыти с металлом.The purpose of the invention is to improve the adhesion of the coating to the metal.
Это достигаетс тем, что она содержит указанные компоненты в следующих количествах (в вес. %): SiOa 25-35; ВаО 55-65; ТЮа 8-12; и, кроме того, АЬОз 2,3-2,7; Na2O + 4-К20 0,8-1,2.This is achieved by the fact that it contains these components in the following amounts (% by weight): SiOa 25-35; BaO 55-65; Tyu 8-12; and, in addition, ABOZ 2.3-2.7; Na2O + 4-K20 0.8-1.2.
Эмаль в виде щликера нанос т на обезжиренную поверхность легированной стали или сплава. Состав щликера (в вес. ч.): фритта- 95, глина Часов-Ярска - 5, долевой шпат - 5, вода - 50.The enamel in the form of slip is applied to the degreased surface of alloyed steel or alloy. The composition of the shlykera (in weight parts): frit-95, clay Chasov-Yarsk - 5, fractional spar - 5, water - 50.
Толщина покрыти 80-90 мкм.Coating thickness 80-90 µm.
Температура обжига покрыти 1150- 1180°С.The firing temperature of the coating is 1150-180 ° C.
Коэффициент термического расширени стекла 122,5-10-7 град- - 27 IQ- град-.The coefficient of thermal expansion of glass is 122.5-10-7 degrees - - 27 IQ- degrees-.
Повышенный коэффициент термического расширени позвол ет примен ть эмаль дл защиты сталей ,и сплавов, работающих в газовой среде при f 900°C.The increased thermal expansion coefficient allows the use of enamel to protect steels and alloys that operate in a gaseous environment at f 900 ° C.
