эо Изобретение относитс к металлургии , а именно к химико-термической обработке металлов и сплавов в порошковых насыщающих средах, и может быть использовано в машиностроительной и приборостроительной промышленности . Известен состав j дл алюмомеднени стальных изделий содержащий, мас.%: Алюминий73 Медь27 , Обработка стальных изделий в указанном составе приводит к формированию хрупкого диффузионного сло небольшой толщины (40 мкм), характеризующегос повьипенной дефектностью, что в значительной мере снижает коррозионную стойкость изделий. Наиболее близким к предлагаемому по технической сущности и достигаемо му эффекту вл етс порошкообразный состав 2J дл алюмомеднени титановых сплавов, содержащий, мас.%:, Порошок алюмини 25 Оксид меди40 Фтористый алюминий 5 Оксид алюмини Остальное Указанный состав используетс дл повышени износостойкости и Жаростойкости титана и его сплавов. Использование известного состава дл обработки стальных изделий позв л ет увеличить их жаростойкость, но из-за наличи пор в диффузионном слое они имеют пониженное сопротивление протеканию процессов коррозии в морской среде. Цель изобретени - повьш1ение коррозионной стойкости изделий в ат мосфере морского воздуха. Указанна цель достигаетс тем, что порошкообразный состав дл алюмомеднени , содержащий алюминий, окись алюмини , медьсодержащее вещество и активатор, дополнительно содержит железо, в качестве медьсодержащего вещества использована медь, а в качестве активатора - хлористый аммоний при следующем соотношении компонентов, мас.%: Алюминий Хлористый аммоний Железо Окись алюмини Остальное Насыщение в предлагаемой порошковой среде осуществл ют при 950°С 4 ч в контейнерах с плавким затвором . Испытани провод т 20 сут в услови х морской атмосферы при 20°С и относительной влажности 95% (ГОСТ 9.040-74). Сравнительные данные по коррозионной стойкости стали 45 в услови х морской атмосферыпри использовании известного и предлагаемого составов приведены в таблице. Коррозионную стойкость оценивают по потере массы на единицу площади поверхности образца за 20 сут испытаний . I Из приведенных данных следует, что алюмомеднение стали 45 в предлагаемых составах (примеры 2-4) позвол ет увеличить в 4,0-4,7- раз коррозионную стойкость покрыти в услови х морской атмосферы по сравнению с известным составом. Изменение соотношени компонентов среды (примеры 1 и 5) понижает коррозионную стойкость изделий из-за недостаточного количества меди в диффузионном покрытии в первом случае и изза увеличени пористости покрыти во втором.This invention relates to metallurgy, namely to the chemical and heat treatment of metals and alloys in powder saturating media, and can be used in the engineering and instrument-making industry. Known composition j for aluminum-copper-containing steel products, wt.%: Aluminum73 Copper27, Processing of steel products in the specified composition leads to the formation of a brittle diffusion layer of small thickness (40 microns), which is characterized by puffiness, which significantly reduces the corrosion resistance of products. The closest to the proposed technical essence and the achieved effect is the powder composition 2J for aluminum titanium alloys containing, in wt.%: Aluminum powder 25 Copper oxide 40 Aluminum fluoride 5 Alumina Rest The specified composition is used to improve the wear resistance and heat resistance of titanium and its alloys. The use of a known composition for treating steel products makes it possible to increase their heat resistance, but because of the presence of pores in the diffusion layer, they have a reduced resistance to the course of corrosion processes in the marine environment. The purpose of the invention is to increase the corrosion resistance of products in the atmosphere of sea air. This goal is achieved by the fact that the powdered composition for aluminum and copper containing aluminum, alumina, copper-containing substance and activator, additionally contains iron, copper is used as copper-containing substance, and ammonium chloride is used as activator in the following ratio, wt.%: Aluminum Ammonium Chloride Iron Alumina Rest The saturation in the proposed powder medium is carried out at 950 ° C for 4 hours in containers with a fusible closure. The tests were carried out for 20 days in conditions of the marine atmosphere at 20 ° C and a relative humidity of 95% (GOST 9.040-74). Comparative data on the corrosion resistance of steel 45 under the conditions of the marine atmosphere when using the known and proposed compositions are given in the table. Corrosion resistance is assessed by the mass loss per unit surface area of the sample over the 20 days of testing. I From the above data, it follows that the aluminum casting of steel 45 in the proposed compositions (examples 2-4) makes it possible to increase by 4.0–4.7 times the corrosion resistance of the coating under the conditions of the marine atmosphere compared with the known composition. Changing the ratio of medium components (examples 1 and 5) reduces the corrosion resistance of the products due to the insufficient amount of copper in the diffusion coating in the first case and due to the increase in the porosity of the coating in the second.
