Установлено, что наплавка с ВМП способствует увеличению объемной доли игольчатого феррита, и уменьшению количества видманштеттова феррита в наплавленном металле. 2. Показано, что значения микротвердости наплавленного металла и зон термического влияния композиций, полученных с ВМП выше микротвердости композиций, полученных без ВМП. 3. Выявлено, что наибольшей износостойкостью характеризуется наплавленный металл, полученный с ВМП. Список литературы 1.
