М. Кеддам, М. Кулька

Аннотация


Интегральным методом смоделирована кинетика роста слоев γ'-фазы при азотировании Армко-железа в камере микроволнового разряда. Полученное решение системы дифференциальных алгебраических уравнений использовано для оценки значений коэффициента диффузии азота в слоях γ'-фазы в области температур 773 - 843 К при поверхностной концентрации азота 5,9 % (масс.). Рассчитанное значение энергии активации диффузии азота и предсказанные значения толщины слоя γ'-фазы сопоставлены с литературными данными.

Ключевые слова


азотирование; нитрид железа; интегральный метод; кинетика роста; nitriding; iron nitride; integral method; growth kinetics
