Description
Изобретение относит1с к составу эмали, используемой дл образовани стекло.кристаллического покрыти на легированных стал х и сплавах.The invention relates to the composition of the enamel used to form a glass crystal coating on alloyed steels and alloys.
Известна эмаль, включающа SiO2, АЬОз, MgO, TiOz, Li2O, NaaO.Enamel is known, including SiO2, ABO3, MgO, TiOz, Li2O, NaaO.
Предлагаема эыалъ обладает повышенным коэффициентом термического раснлирени , мало измен ющимс .при ситаллизации, улучшенными защитными свойствами.The proposed formulation has a high thermal dilution coefficient, which does not change much during sitalization, and has improved protective properties.
Это достигаетс тем, что она содержит указанные компоненты в следующих количествах , шее. %: Si02 48,4-54,4; АЬОз 16,1 - 19,4;This is achieved in that it contains these components in the following amounts, the neck. %: Si02 48.4-54.4; ABOZ 16.1 - 19.4;
Толщина двухслойного .покрыти После обжига не должна превышать 60 ./икл. Температура обжига грунтового покрыти , в зависимости от содержани Сг2Оз колеблетс от 1050 до 1150°С, нокроеного сло -1050°С.The thickness of the double-layer. After firing should not exceed 60. / Cycle. The firing temperature of the primer coating, depending on the Cr2Oz content, ranges from 1050 to 1150 ° C, but the thickness of the layer is –1050 ° C.
MgO 11,8-14,6; TiOa 9-12; LizO 3-5; ЫагО 5-7; и кроме того сверх 100% К2О до 30, Сг2Оз до 30.MgO 11.8-14.6; TiOa 9-12; LizO 3-5; Yo 5-7; and besides, in excess of 100% K2O up to 30, Cr2Oz up to 30.
Коэффициент термического расщирени давней эмали 117-10 гра&- ; :после ситаллизации- 122-10 град, начала разм гчени до 580°С; температура обжига 1покрыти до 1050°С. Микротвердость ситаллизированного покрыти 1892 кг/мл1-.The coefficient of thermal expansion of the old enamel 117-10 gra &-; : after sitalization, 122–10 degrees, the onset of softening to 580 ° C; firing temperature 1cover to 1050 ° C. The microhardness of the crystallized coating is 1892 kg / ml1-.
Эмаль нанос т на обезжиренную поверхность .хромоникелевого сплава ЭИ-435 в виде шликера состава (в вес. ч.)The enamel is applied to the degreased surface of the EI-435 nickel alloy in the form of a slip composition (in weight parts)
ни не более 3°С в минуту в интервале тем15 ператур нуклеации (590-640°С) ,и выдержкой в течение двух часов при оптимальной температуре кристаллизации (730°С).Not more than 3 ° C per minute in the range of nucleation temperatures (590–640 ° C), and exposure for two hours at the optimum crystallization temperature (730 ° C).
эмали повышаетс с 580 до 900°С, а покров .ной -до 860°С.enamel rises from 580 to 900 ° C, and the cover of the enamel rises to 860 ° C.
Эмали при введении в шликер от 5 до 30% СгаОз могут служить грунтовым слоем или самосто тельным покрытием на сплаве ЭИ-435 |при температуре эксплуатации 900- 1000°С, а эмали б&з доба,вки СгаОз могут быть использованы а качестве покровиой эмали при температуре 900°С в газовой среде.Enamels, when introduced into the slip from 5 to 30% of CO2, can serve as a base coat or an independent coating on the alloy EI-435 | at a operating temperature of 900-1000 ° C, and enamels can be used as a coating of enamel at a temperature of 900 ° C in a gaseous environment.
