Abstract
1. Способ химико-термической обработки металлических изделий, размещенных в контейнере с электропроводной порошковой средой, содержащей легирующий элемент, включающий пропускание через нее электрического тока с помощью электродов, одним из которых является изделие, отличающийся тем, что в качестве другого электрода электрической цепи используют контейнер, а в качестве электропроводной порошковой среды используют горючий материал, имеющий температуру возгорания, ниже температуры плавления материала обрабатываемого изделия.2. Способ по п.1, отличающийся тем, что контейнер выполнен в форме, копирующей форму зоны поверхности изделия, подлежащей упрочнению.3. Способ по п.1, отличающийся тем, что изделие располагают эквидистантно относительно контейнера.4. Способ по п.1, отличающийся тем, что соотношение площадей контейнера и изделия составляет величину не менее 10:1.1. The method of chemical-thermal treatment of metal products placed in a container with an electrically conductive powder medium containing an alloying element, comprising passing an electric current through it using electrodes, one of which is a product, characterized in that the container is used as the other electrode of the electric circuit and as an electrically conductive powder medium, a combustible material having an ignition temperature lower than the melting temperature of the material of the workpiece is used. 2. The method according to claim 1, characterized in that the container is made in a shape that copies the shape of the surface area of the product to be hardened. The method according to claim 1, characterized in that the product is arranged equidistantly relative to the container. The method according to claim 1, characterized in that the ratio of the areas of the container and the product is at least 10: 1.
