Introduction. In modern mechanical engineering, there is a growing trend toward the development and implementation of novel heat-resistant alloys with enhanced physical and mechanical properties. Electrical discharge machining (EDM) is a promising method for manufacturing products from these new-generation heat-resistant alloys. This paper presents an analysis of current research in the field of EDM of heat-resistant alloys. The primary focus is on analyzing output qualitative and quantitative indicators in relation to input parameters — machining mode and conditions. The key factors influencing the efficiency of EDM are considered, including machining parameters and the composition of the working fluid and electrode material. This analysis of current research is intended for specialists in the field of heat-resistant alloy machining, developers of EDM technologies, and researchers working to improve manufacturing methods for aircraft engine components. The purpose of this work is to conduct a literature review of existing research on modern methods for ensuring and improving the efficiency and quality of electrical discharge machining (EDM) of heat-resistant materials. The methods of investigation involved a theoretical analysis of current research on electrical discharge machining of heat-resistant alloys. Results and discussion. A literature analysis was conducted, and it revealed that current strength and pulse duration are the main technological parameters determining the quality of the processed surface and the material removal rate. The effectiveness of using modified working fluids (with graphene and carbon nanotubes) during heat-resistant material processing to improve surface quality was confirmed. It is of particular interest to conduct experimental studies on the influence of adding various material components to the working fluid to improve surface quality indicators after complex pulse electrical discharge machining (CPEDM) and to assess the impact of these alloying materials on the surface layer of heat-resistant materials.

Введение. В современном машиностроении наблюдается тенденция к разработке и внедрению новых жаропрочных сплавов с повышенными физико-механическими свойствами. Перспективным способом изготовления изделий из жаропрочных сплавов нового поколения является электроэрозионная обработка. В настоящей статье представлен анализ современных исследований в области электроэрозионной обработки жаропрочных сплавов. Основное внимание уделяется анализу выходных качественных и количественных показателей, которые зависят от входных параметров – режима обработки и условий обработки. Рассмотрены ключевые факторы, влияющие на эффективность электроэрозионной обработки: режимы обработки, состав рабочей жидкости, материал электродов. Материалы анализа современных исследований представляют интерес для специалистов в области обработки жаропрочных сплавов, разработчиков технологий электроэрозионной обработки и исследователей, работающих над совершенствованием методов изготовления изделий для авиадвигателестроения. Цель работы: обзор научной литературы, посвященной исследованиям современных методов обеспечения и повышения эффективности и качества электроэрозионной обработки жаропрочных материалов. Методы исследования: теоретический анализ современных исследований на тему электроэрозионной обработки жаропрочных сплавов. Результаты и обсуждение. Проведен анализ литературы, на основании которого установлено, что сила тока и время включения импульса являются основными технологическими параметрами, определяющими качество обработанной поверхности и скорость съема материала. Установлена эффективность применения модифицированной рабочей жидкости (с добавлением графена и углеродных нанотрубок) при обработке жаропрочных материалов для улучшения качества поверхности. Актуальным представляется проведение экспериментальных исследований влияния компонентов различных материалов, добавляемых в рабочую жидкость, для улучшения показателей качества поверхности после КПЭЭО, а также исследование влияния легирования данными материалами поверхностного слоя жаропрочных материалов.
