Abstract
Изобретение относитс к защите металла от коррозии и может быть использовано в приборостроительной и металлургической промышленности. Цель изобретени - повышение термостойкости покрыти и снижение продолжительности цикла получени покрыти . Способ включает очистку и обезжиривание поверхности металла, нанесение на нее композиции полифосфата кальци с алюминиевой пудрой при соотношении 1 : 2 - 1 : 4, термообработку при 750-800°С 1-3 мин, нанесение порошкообразного цинка и термообработку при 840-860°С 5-7 мин. Повышение термостойкости покрыти и снижение продолжительности цикла получени покрыти достигаетс за счет нанесени полифосфата кальци с алюминиевой пудрой, термообработки, нанесени порошкообразного цинка и последующей дополнительной термообработки. 3 табл.The invention relates to the protection of metal against corrosion and can be used in instrument-making and metallurgical industries. The purpose of the invention is to increase the heat resistance of the coating and reduce the duration of the cycle for obtaining the coating. The method includes cleaning and degreasing the metal surface, applying a calcium polyphosphate composition with aluminum powder on it at a ratio of 1: 2 - 1: 4, heat treatment at 750-800 ° C for 1-3 minutes, applying zinc powder and heat treatment at 840-860 ° C 5-7 min. Increasing the heat resistance of the coating and reducing the cycle time for obtaining the coating is achieved by applying calcium polyphosphate with aluminum powder, heat treatment, deposition of powdered zinc and subsequent additional heat treatment. 3 tab.
Description
Изобретение относитс к защите металла от коррозии и может быть использовано в приборостроительной и машиностроительной промышленности.The invention relates to the protection of metal against corrosion and can be used in the instrument-making and engineering industries.
Цель изобретени - повышение термостойкости покрыти и снижение продолжительности цикла получени покрытий .The purpose of the invention is to increase the heat resistance of the coating and reduce the cycle time for obtaining coatings.
Изобретение иллюстрируетс следующими примерами.The invention is illustrated by the following examples.
На предварительно очищенную, обезжиренную и нагретую до 80-90°С поверхность стали ЗОхГСА наносили водную суспензию, содержащую полифосфат кальци и алюминиевую пудру. Затем покрытие подвергали термообработке, после чего обрабатывали водной суспензиейAn aqueous suspension containing calcium polyphosphate and aluminum powder was applied to the surface of the AOXGSA steel, previously cleaned, degreased and heated to 80-90 ° C. Then the coating was subjected to heat treatment, and then treated with an aqueous suspension
порошкообразного цинка (при соотношении цинк:вода, равном 1:1) и снова подвергали термообработке.powdered zinc (at a ratio of zinc: water, equal to 1: 1) and again subjected to heat treatment.
Зависимость качества покрыти от режима обработки приведена в табл. 1,The dependence of the quality of the coating on the processing mode is given in Table. one,
Зависимость качества покрыти от величины соотношени полифосфата кальци и алюминиевой пудры следукгща :The dependence of the quality of the coating on the ratio of calcium polyphosphate and aluminum powder follows:
