Description
;54) ПОРОШКОВЫЙ СОСТАВ ДЛЯ ДИФФУЗИОННОГО ЦИНКОВАНИЯ ДЕТАЛЕЙ ИЗ АЛЮМИНИЕВЫХ СПЛАВОВ; 54) POWDER COMPOSITION FOR DIFFUSION GALVANIZING DETAILS OF ALUMINUM ALLOYS
Изобретение относитс к металлургии , а именно к химико-термической обработке алюмини и его сплавов в порошковых средах и может быть использовано дл повышени эксплуатационных характеристик издел ий из алюмини и его сплавов, примен емых в приборостроительной, авиационной, машиностроительной и электронной промышленности .The invention relates to metallurgy, in particular to the chemical heat treatment of aluminum and its alloys in powder media and can be used to improve the performance characteristics of aluminum and its alloys used in the instrument-making, aviation, engineering and electronics industries.
Наиболее близким к предлагаемому по технической сущности и достигаемому эффекту вл етс состав jTl дл диффузионного цинковани алюмини и его сплавов, содержащий, мас.%: Zn 25, А1 25, 47, 3.The closest to the proposed technical essence and the achieved effect is the composition jTl for the diffusion galvanizing of aluminum and its alloys, containing, in wt.%: Zn 25, Al 25, 47, 3.
В результате термодиффузионной обработки сплава Д16 в известном составе при 4 ч формируетс диффузионный слой толщиной 280 мкм. При использовании диффузионно-упрочненных алюминиевых деталей дл нужд электронной , химической и приборостроительной промышленности така толщина сло не всегда вл етс достаточной.As a result of the thermal diffusion treatment of the alloy D16 in a known composition, a diffusion layer with a thickness of 280 µm is formed at 4 hours. When using diffusion-hardened aluminum parts for the needs of the electronic, chemical and instrument-making industry, such a thickness of the layer is not always sufficient.
Цель изобретени - интенсификаци процесса насыщени .The purpose of the invention is to intensify the saturation process.
Дл достижени указанной цели в известную порошковую смесь, содержащую окись алюмини , цинк и алюминий, дополнительно ввод ть медь и фтористый кальций при следующем соотношении ингредиентов, мас.%:To achieve this goal, additionally inject copper and calcium fluoride in the following powder mixture containing alumina, zinc and aluminum in the following ratio of ingredients, wt%:

Пример . Цинкование в предлагаемой порошковой среде осуществл ют в контейнерах с плавким затвором при 500С 4 ч. При этом на алюминии мар15 ки Д16 формируетс диффузионный слой толщиной 400-420 мкм.An example. Zincing in the proposed powder medium is carried out in containers with a fusible plug at 500 ° C for 4 hours. In this case, a diffusion layer 400–420 µm thick is formed on the aluminum grade D16.
Сравнительные данные по толщине диффузионных слоев, формирующихс при обработке из известного и пред20 лагаемого составов на сплаве Д16, приведены в таблице.Comparative data on the thickness of the diffusion layers formed during the processing of the known and proposed compositions on the D16 alloy are given in the table.
Из приведенных данных следует, что цинкование с использованием 25 предлагаемого состава позвол ет увеличить толщину диффузионного сло в 1,3-1,4 раза.It follows from the above data that galvanizing using 25 the proposed composition allows to increase the thickness of the diffusion layer by 1.3-1.4 times.
Это значительно расшир ет области промышленного цинковани алюминие30 вых сплавов.This greatly expands the field of industrial galvanizing of aluminum30 alloys.
