Аннотация


Исследовано влияние режимов искрового плазменного спекания (SPS) на структуру и свойства самофлюсующегося материала системы Ni - Cr - Si - B - С. Определены структура и фазовый состав образцов с использованием методов световой и растровой электронной микроскопии, а также пористость и микротвердость полученного материала. Проведены триботехнические испытания образцов в условиях трения о закрепленные частицы абразива. Установлены режимы SPS порошка ПР-Н77Х15С3Б2, позволяющие получить Ni - Cr - Si - B - С-сплав с минимальной пористостью и максимальными микротвердостью и износостойкостью.

Ключевые слова


система Ni - Cr - Si - B - С; самофлюсующийся сплав; искровое плазменное спекание; SPS
