Изобретение относитс к области химикотермической обработки.This invention relates to the field of chemical heat treatment.
Известна регенерируюпда смесь, примен ема при диффузионном хромировании, содержаща хлористый аммоний и хром.A regenerated mixture known for diffusion chromium containing ammonium chloride and chromium is known.
Предлагаема смесь отличаетс от известной введением алюмини и повышенным содержанием хлористого аммони . Это позвол ет повысить регенерирующую способность смеси.The proposed mixture differs from the known introduction of aluminum and a high content of ammonium chloride. This increases the regeneration capacity of the mixture.
Смесь имеет следующий состав, вес. %: Алюминий3,7-16The mixture has the following composition, weight. %: Aluminum3,7-16
Хлористый аммоний 3,7- 8 ХромОстальноеAmmonium chloride 3,7- 8 Chromium Else
Вместо хрома смесь может содержать феррохром . Регенерирующую смесь добавл ют перед каждой операцией диффузионного хромировани в количестве 5,4-13% от веса хромирующей смеси, располага «е менее чемInstead of chromium, the mixture may contain ferrochrome. Before each diffusion chromium plating, the regenerating mixture is added in the amount of 5.4-13% by weight of the chromium plating mixture; it is less than
в 5 мм от детали (дл исключени налипани ) .5 mm from the part (to prevent sticking).
Добавление регенерирующей смеси сохран ет на одном уровне хромирующую способность смеси вплоть до 60-кратного использовани , а также устран ет обезуглероживание деталей.The addition of the regenerating mixture maintains the level of chromizing ability of the mixture up to 60 times, and also eliminates decarburization of parts.
