Description

Изобретение относитс  к хи.микотермической обработке алюмини  и его сплавов в порошкообразных средах и может быть использовано дл  повышени  эксплуатационных характеристик изделий из алюмини  и его сплавов, примен емых в приборостроительной, авиационной и машиностроительной област х техники. Известны составы порошковых насыщающих сред, содержащие цинк и окись кремни  1 . Химико-термическа  обработка в известной среде позвол ет получить н алюминиевом сплаве АК -1 дифф1 зионный слой толщиной не более 140 мкм. Известен также состав дифг .фузионного цинковани  алюмини и его сплавов, содержащий,мас.: 25 Zn + 25 AI + 47 AlQO,j+ 3 Однако в результате термодиффузион ной обработки алюмини  марки АД 1 и сплава АМг в известном составе при в течение Ч ч формируетс  диффузионный слой толщиной НС более 210 мкм и 220 мкм соответственно . Цель изобретени  - повышение насыщающей способности состава. Дл  достижени  указанной цели в порошковую смесь, содержащую окись алюмини , цинк, алюминий и хлористый аммоний, дополнительно ввод т окись титана при следующем соотношении ингредиентов, мас.: Окись алюмини  25-32 Алюминий 2,,k Цинк20-30 Хлористый аммоний1-3 Окись титака 29,,6 Цинкотитанирование в предлагаемой порошковой среде осуществл ют в контейнерах с плавкими затворами. При этом на алюминии марки АД1 и наThe invention relates to the chemical heat treatment of aluminum and its alloys in powdered media and can be used to improve the performance characteristics of products made of aluminum and its alloys used in instrument-making, aviation and engineering industries. Known compositions of powdered saturating media containing zinc and silicon oxide 1. Chemical thermal treatment in a known medium makes it possible to obtain an aluminum alloy AK -1 diffusion layer with a thickness of not more than 140 microns. Also known is the composition of diffusive galvanizing aluminum and its alloys, containing, wt .: 25 Zn + 25 AI + 47 AlQO, j + 3 However, as a result of thermal diffusion treatment of aluminum of the brand BP 1 and the AMg alloy, a diffusion layer with a NS thickness of more than 210 μm and 220 μm, respectively. The purpose of the invention is to increase the saturability of the composition. To achieve this goal, titanium oxide is added to the powder mixture containing alumina, zinc, aluminum, and ammonium chloride in the following ratio of ingredients, wt .: Aluminum oxide 25-32 Aluminum 2,, Zinc20-30 Ammonium chloride 1-3 Oxide Titaca 29, 6, Zincothitanation in the proposed powder medium is carried out in containers with fusible closures. At the same time, on aluminum grade АД1 and on
