Пример. Дл приготовлени обмазки предложенного состава компоненты берут в указанном соотношении. Коллоксилин раствор ют в смеси амилацетата и диэтилоксалата) затем в по лученный раствор св зующего добавл ют наполнитель - смесь алюмини в виде пудры и порошка окиси алюмини . В зкость обмазки должна составл ть от 20 до 25 сек по визкозиметру Example. To prepare the coating of the proposed composition, the components are taken in the specified ratio. The colloxylin is dissolved in a mixture of amyl acetate and diethyl oxalate) and then a filler — a mixture of aluminum in the form of powder and alumina powder — is added to the resulting binder solution. The viscosity of the coating should be from 20 to 25 seconds using a viscometer.

Приготовленную обмазку тщательно перемешивают и нанос т на поверхность металлических изделий с нанесенным слоем алюмини пульверизатором (или окунанием); сушат на воздухе.The prepared coating is thoroughly mixed and applied to the surface of metal products with an aluminum layer applied with a spray gun (or dipping); air dried.
Издели с нанесенной обмазкой подвергают диффузионному отжигу при температуре 700-950 С в течение 2-3 час. Несгоревшие частицы обмазки удал ют щеткой.The coated products are subjected to diffusion annealing at a temperature of 700-950 C for 2-3 hours. The unburned smear particles are removed with a brush.
Предложенна обмазка полностью.The proposed coating completely.
10 предохран ет алитированные издели от выгорани алюмини при диффузионном отжиге и обеспечивает получение изделий с хорошим товарным видом и высоким качеством поверхности ( отсутствуют дефекты в виде наплывов,10 prevents aluminized products from burning aluminum during diffusion annealing and provides products with a good presentation and high surface quality (there are no defects in the form of sagging,
