Abstract
1. Data are presented on the effects of the amount of chromium in the starting charge on the chromium content of iron-chromium alloy powders of various compositions, obtained under different conditions of diffusion impregnation from point sources. It was established that the maximum chromium content of alloys of various compositions and maximum coefficients of chromium recovery from the starting charge correspond to a temperature of 1100°C. In addition, only a relatively small amount of chlorides remains in sponge after diffusion impregnation at this temperature. 2. The coefficient of chromium recovery from the starting charge in diffusion impregnation from point sources is higher than for impregnation from solid packing materials.
