ВЛИЯНИЕ МЕХАНОАКТИВАЦИИ НА СПЛАВЫ WC

В настоящей работе представлен обзор исследований, направленных на получение сплавов на основе карбида вольфрама с предварительно проведенной механоактивацией (МА). МА широко применяется в области материаловедения и направлена на изменения физико-механических свойств материалов с целью повышения активности их реакции при проведении исследований. В связи с этим, основное внимание в данной статье направлено на исследование влияния механоактивации на смеси на основе карбида вольфрама (WC). Твердые сплавы на основе WC используются в различных промышленных условиях, благодаря их отличным механическим свойствам и выдающейся износостойкости в сочетании с высокой прочностью и термостойкостью, более того больше половины производства твердых сплавов на основе WC связана с изготовлением режущих инструментов. В статье также приведены комплексные виды механической активации, применяемых в различных исследованиях. А также рассмотрено влияние видов механоактивации смесей и длительности ее проведения на физико-механические свойства полученных сплавов последующими методами синтеза. Проведен анализ оптимальных условий для консолидации порошков методом искро-плазменного спекания (ИПС), что позволяет достигать высокой плотности и прочности материалов.
