Abstract
Description
Изобретение относится к области химикотермической обработки, а именно к процессам многокомпонентного насыщения металлов и сплавов. The invention relates to the field of chemical thermal treatment, and in particular to processes of multicomponent saturation of metals and alloys.
Известен состав для диффузионного насыщения (см. авт. св. N 836205, C 23 C 10/52, 1981), который содержит, мас. A known composition for diffusion saturation (see ed. St. N 836205, C 23
Никельалюминид 50 70;
Алюминий фтористый 1 3;
Алюминия окись 27 49.Nickel Aluminides 50 70;
Однако из известного состава не удается получить на медных сплавах диффузионные слои глубиной более 370 490 мкм. Потому что на обрабатываемых поверхностях образуются химические соединения Cu Ni Al, снижающие проникновение активных атомов насыщающего элемента в глубь изделий, а также недостаточный градиент адсорбированных поверхностью изделия атомов диффузантов. However, from the known composition, it is not possible to obtain diffusion layers on copper alloys with a depth of more than 370,490 μm. Because on the treated surfaces chemical compounds Cu Ni Al are formed, which reduce the penetration of active atoms of the saturating element into the interior of the products, as well as an insufficient gradient of diffusant atoms adsorbed on the surface of the product.
Изобретение направлено на интенсификацию процесса диффузионного насыщения. The invention is directed to the intensification of the diffusion saturation process.
Решение поставленной задачи достигается тем, что порошковая смесь, содержащая никельалюминид, алюминий фтористый и алюминия окиси, дополнительно содержит порошки меди и железа при следующем соотношении ингредиентов, мас. The solution to this problem is achieved by the fact that the powder mixture containing Nickel, aluminum fluoride and aluminum oxide, additionally contains powders of copper and iron in the following ratio of ingredients, wt.
Медь 10 12;
Железо 5 15;
Никельалюминид 39 55;
Алюминия окись 27 35;
Алюминий фтористый 1 3.
Iron 5 15;
Пример. Процесс насыщения проводят на медных образцах в металлических контейнерах с плавким затвором в течение двух часов при температуре 950oC.Example. The saturation process is carried out on copper samples in metal containers with a fuse for two hours at a temperature of 950 o C.
Сравнительные данные по насыщающей способности предлагаемого состава на меди представлены в таблице. Comparative data on the saturation ability of the proposed composition on copper are presented in the table.
Таким образом, при химико-термической обработке медных изделий из предлагаемого состава скорость насыщения увеличивается в 1,5 1,8 раза. Thus, during the chemical-thermal treatment of copper products from the proposed composition, the saturation rate increases by 1.5 1.8 times.
