Description

Дл  выбора оптимального состава рвгенериругошей , добавки исследуют три состава, содержащие каждый (в весЛ): феррованади  20, хлористого аммони  1, карбюризатора древесноугольного 2, остальное ферромолибден и отличающиес  друг от друга содержанием титана, равным в каждой смеси последовательно (в вес. %) 5,10 и 15, Результаты обработки представлены в таблице.In order to select the optimal composition of rhinericheskids, the additives examine three compositions each (in weight): ferrovanadium 20, ammonium chloride 1, charcoal carburizer 2, the rest is ferromolybdenum and differing from each other in titanium equal to each mixture successively (in wt.%) 5,10 and 15, The results of processing are presented in the table.

Как видно из .данных таблицы, оптимальной регенерирующей добавкой  вл етс  состав, содержащий 1О титана.As can be seen from the table, the optimal regenerating additive is a composition containing 1O titanium.

Регенерирующую смесь добавл ют перед каждой операцией диффузионного карболегировани  в количестве 5-10 вес.% от первоначального веса исходной смеси, располага  не менее чем в 5 мм от деталей (дл  исключени  налипани ).Before each diffusion carboling operation, the regenerating mixture in the amount of 5-10 wt.% Of the initial weight of the initial mixture was added, located not less than 5 mm from the parts (to prevent sticking).

Добавление регенерирующей смеси сохран ет на одном уровне карболегирующую способность, поввол   ее использовать до бО раз, и вследствие активности смеси устран ет обезуглероживанне де талей при насыщении,The addition of the regenerating mixture retains the carbolgating ability at the same level, it can be used up more than once, and, due to the activity of the mixture, eliminates decarburized parts at saturation,
