FIELD: chemical-thermal treatment of parts in circulating gas medium.
SUBSTANCE: proposed method includes heating and saturation of part surface with several diffusing components simultaneously in circulating halogenide medium which is formed at contact of starting gas medium with sources of diffusing components. Sources of diffusing components are chromium and chromium alloy and aluminum alloy. Content of chromium in alloy ranges from 30 to 75%, the remainder being aluminum. Diffusing components have the following composition: chromium 30-90%; chromium and aluminum alloy, 10-70%.
EFFECT: enhanced durability of coat.
