А. Джалик, Н. Еныай, Н. Уджар

Аннотация


Исследовано влияние температуры и длительности борирования на нанотвердость и модуль упругости стали 16MnCr5 (российский аналог — сталь 16ХГ). Проведено пакетное борирование в твердой среде при температурах 1123 – 1223 К в течение 2 – 6 ч с использованием реагента Экабор-2 (Экабор-II). Анализ результатов экспериментов показал эффективность метода наноиндентирования для оценки качества и свойств борированного слоя стали 16MnCr5. Установлено, что значения нанотвердости и модуля упругости стали находятся в пределах 587,5 – 3716,4 МПа и 63,3 – 159,7 ГПа соответственно.

Ключевые слова
