Description
но стабильно получать поверхность с чистотой 0,63.but stable to obtain a surface with a purity of 0.63.
При диффузионном насьпдении поверхности детали хромом и алюминием первым начинает свое проникновение алюминий . Хром, двига сь вслед за алюминием , отсасывает на себ углерод, раствор графит и св зыва его в карбиды.When diffusing on the surface of a part with chrome and aluminum, aluminum first begins to penetrate. Chromium, moving after aluminum, sucks carbon, graphite solution, and binds it to carbides.
На поверхности хромоалитированных чугунных изделий наблюдаетс образование трех зон: карбидной, перлитообразной и обезуглероженной.The formation of three zones is observed on the surface of chromoalyzed cast iron products: carbide, perlite-like and decarbonized.
Пример 1. Провод т хромоалитирование деталей из чугуна и сталиExample 1. Chromo-analysis of parts made of iron and steel is carried out.
в контейнере, который устанавливают в обычную электротермическую печь. Температура обработки 950°С; врем вьщержки 4,6 ч.in a container that is installed in a conventional electrothermal furnace. Processing temperature 950 ° C; delivery time 4.6 hours
Пример 2. Провод т хромоалитирование деталей из чугуна и стали в контейнере, который устанавливают в Обычную электротермическую печь. Температура обработки врем выдержки 8ч.Example 2. Chromo-analysis of parts made of iron and steel is carried out in a container that is installed in a conventional electrothermal furnace. Processing temperature holding time 8h.
Зависимость общей глубины диффузионной зоны от химического состава композиционной смеси, температуры отжига и времени выдержки представлена в таблице.The dependence of the total depth of the diffusion zone on the chemical composition of the composite mixture, the annealing temperature and the exposure time are presented in the table.
