Изобретение относитс к химико-термической обработке, в частности к процессам насыщени при электролитном налреве.This invention relates to chemical heat treatment, in particular to saturation processes in electrolyte heating.
Известен способ цианировани стали при нагреве в электролите при катодном процессе.A known method of cyanidation of steel when heated in an electrolyte during the cathodic process.
Предлагаемый способ отличаетс от известного тем, что нагрев осуществл ют при анодном процессе в электролите следующего состава , %:The proposed method differs from the known one in that the heating is carried out at an anodic process in an electrolyte of the following composition,%:
Азотна кислота5-10Nitric acid 5-10
Хлористый аммоний5-15Ammonium Chloride5-15
Глицерин10-15Glycerin 10-15
ВодаОстальное.Water the rest.
Указанное отличие позволит устранить эрозию обрабатываемого издели п повысить экономичность процесса за счет снижени расхода электроэнергии.This difference will eliminate the erosion of the processed product and increase the efficiency of the process by reducing energy consumption.
В предлагаемом способе изделие служит анодом. При анодном процессе изделие практически не подвергаетс электрической эрозии под действием тлеющего разр да, протекающего в парогазовой оболочке между металлическим анодом и элект|ролитиым катодом,In the proposed method, the product serves as an anode. During the anodic process, the product is practically not subjected to electrical erosion under the action of a glow discharge flowing in the vapor-gas sheath between the metal anode and the electrolytic cathode,
так как в этом случае возникновение дуговых разр дов невозможно (отсутствует термоэлектронна эмисси с катода).since in this case the occurrence of arc discharges is impossible (there is no thermoelectronic emission from the cathode).
Способ позвол ет плавно регулировать температуру в диапазоне 300-950°С, что особенно важно при азотировании.The method allows the temperature to be smoothly controlled in the range of 300-950 ° C, which is especially important when nitriding.
При Цианировании ст. 3 (Т-850°, 4 мин) глубина диффузионного сло составл ет 0,19 мм при твердости Ну 700 кг/мм.During the Cyanization of Art. 3 (T-850 °, 4 min), the depth of the diffusion layer is 0.19 mm with a hardness of Well 700 kg / mm.
