Алмазосодержащие материалы для отрезного инструмента на основе железного порошка

Алмазосодержащие материалы для отрезного инструмента на основе железного порошка

Abstract

В статье приведены данные по выбору оптимального состава и разработке технологии изготовления листовых композиционных материалов, предназначенных для изготовления отрезных кругов. Предложены алмазосодержащие композиции на основе смеси порошков Fe-Сu-Ni. Комплекс исследований включал определение технологических свойств порошков, физико-механических характеристик материалов по стандартным методикам, изучение структуры образцов. Структурные исследования проводились методами металлографии, рентгенографии, электронной микроскопии на просвет и растровой электронной микроскопии. Оптимизация технологических факторов проводилась с помощью построения математической модели второго порядка с использованием симметричных композиционных планов Бокса-Бенкина. Проведены испытания изготовленного инструмента в условиях сквозного абразивного резания пластин кремния.
