Description

1one

Изобретение относитс  к области химйкотермической обработки алюмини  и его сплавов .This invention relates to the field of chemical heat treatment of aluminum and its alloys.

Известен состав дл  диффузионного цинковани  алюмини , содержащий компоненты в следующем соотношении, вес. %:A known composition for the diffusion zinc coating of aluminum, containing the components in the following ratio, wt. %:

Цинк75Zinc75

Окись кремни 25Silica 25

Этот состав по технической сущности и достигаемому эффекту наиболее близок к предложенному.This composition by technical essence and the achieved effect is closest to the proposed one.

С целью интенсификации и процесса насыщени  предлагаемый состав дл  диффузионного цинковани  алюмини  и его сплавов дополнительно содержит алюминии, окись алюмини  и хлористый аммоний при следующем соотношении компонентов, вес. %:In order to intensify and saturate the proposed composition for the diffusion galvanizing of aluminum and its alloys additionally contains aluminum, aluminum oxide and ammonium chloride in the following ratio of components, weight. %:

Цинк20-30Zinc 20-30

Алюминий40-50Aluminum 40-50

Хлористый аммоний3-5Ammonium Chloride 3-5

Окись алюмини ОстальноеAlumina Rest

Цинкование осуществл ют в контейнерах с плавкими затворами в интервале температур от 250 до 600°С при выдержках от 1 до 8 ч.Zincing is carried out in containers with fusible closures in the temperature range from 250 to 600 ° C at exposures from 1 to 8 h.

В табл. 1 представлены известный и предлагаемые составы дл  диффузионного цинковани  алюмини  марки АК4; в табл. 2 - результаты их исследовани .In tab. 1 shows the known and proposed compositions for diffusion galvanizing of aluminum grade AK4; in tab. 2 - the results of their research.

Таблица 1Table 1

В результате -цинковани  алюмини  и его сплавов поверхностна  твердость повышаетс  в 2 раза, а коррозионна  стойкость в водных растворах серной и азотной кислот и щелочей увеличиваетс  в 2-4 раза.As a result of the zinc coating of aluminum and its alloys, the surface hardness increases by 2 times, and the corrosion resistance in aqueous solutions of sulfuric and nitric acids and alkalis increases by 2-4 times.
