М. Кеддам, М. Кулька

Аннотация


Проведена оценка энергии активации диффузии бора при твердофазном борировании армко-железа и постоянном времени инкубации образования борида с использованием модели среднего коэффициента диффузии. Осуществлена экспериментальная проверка модели путем борирования армко-железа при 1253 К в течение 5 ч. Получено хорошее соответствие экспериментальной и рассчитанной толщины слоя Fe2B.

Ключевые слова


борирование; бориды железа; время инкубации; метод среднего коэффициента диффузии; энергия активации; boriding; iron borides; incubation time; mean diffusion coefficient (MDC) method; activation energy
