ВЛИЯНИЕ ВАРЬИРОВАНИЯ РАССТОЯНИЯ НАПЫЛЕНИЯ НА СТРУКТУРНО-ФАЗОВОЕ СОСТОЯНИЕ И МЕХАНО-ТРИБОЛОГИЧЕСКИЕ СВОЙСТВА ПОКРЫТИЙ НА ОСНОВЕ 86WC-10CO-4CR, ПОЛУЧЕННЫХ МЕТОДОМ HVOF

В работе приводятся результаты металлографического и трибологического исследования покрытий 86WC-10Co-4Cr, полученных методом HVOF на установке Termikа-3 при варьировании расстояния напыления. Изучается влияние расстояния напыления на микроструктуру покрытия, фазовый состав, а также механические и трибологические свойства. Фазовый состав, микроструктура и распределение элементов анализировались с применением методов рентгеновской дифракции (РФА), сканирующей электронной микроскопии (СЭМ) и энергодисперсионной спектроскопии (ЭДС). Твердость образцов измерялась на микротвердомере по методу Виккерса, коэффициент трения и степень износа исследовались с использованием измерителя трения и износа. Согласно результатам исследования, установлено, что оптимальным расстоянием напыления для нанесения покрытий 86WC-10Co-4Cr с улушенными характеристиками износостойкости и твердости, а также с низкой пористостью, является 300 мм.
