Аннотация


Исследована кинетика борирования низколегированной стали 16MnCr5 при 1123, 1173 и 1223 К длительностью 2, 4 и 6 ч в порошкообразных смесях с использованием агента Экабор-II для определения возможности его применения для повышения поверхностных свойств этой стали. Проведен микроструктурный анализ методами световой и электронной микроскопии, а также рентгеновской дифракции. Определены механические свойства стали, борированной при разных режимах. Показано, что рост боридного слоя во времени описывается параболической зависимостью. Определены энергия активации диффузии при борировании и предэкспоненциальный множитель, получено эмпирическое уравнение для прогнозирования толщины боридного слоя на стали 16MnCr5 в зависимости от времени и температуры борирования. Установлено, что после борирования пределы текучести и прочности стали при растяжении увеличиваются, а пластичность уменьшается. После борирования в течение 6 ч при 1223 К твердость боридного слоя составила 1940 H V0,1 при твердости матрицы 401 HV 0,1 .
