Застосування методів електроіскрового легування для покращення якості поверхневих шарів металевих деталей: фактори та перспективи

Abstract: Problem. In modern mechanical engineering, there is a need to implement advanced technologies to enhance the service life and reliability of components and tools, particularly under extreme conditions. Electro-spark deposition (ESD) is a promising technique for surface modification, but existing studies primarily focus on its energetic aspects, leaving productivity insufficiently explored. This limits ESD’s wider adoption in the industry. Goal. The goal is to optimize the ESD process parameters to maximize its effects, consider specific material requirements and operating conditions, and to explore potential integrations of ESD with other treatment methods, such as chemical-thermal and laser processing. Methodology. The research involves analyzing the ESD process to determine how adjusting various parameters—such as energy, electrode material, alloying environment, processing speed, and cooling mode—affects the quality, durability, and protective properties of coatings against corrosion and wear. Results. The study highlights that a comprehensive approach to optimizing ESD parameters can lead to high-quality coatings, improving production efficiency, lowering costs, and enhancing the overall competitiveness of manufacturing enterprises. Originality. The research offers novel insights by focusing on previously underexplored productivity factors in the ESD process, proposing parameter optimizations to achieve effective surface coatings. Practical Value. The optimized ESD process can reduce manufacturing costs, enhance coating durability and quality, and increase competitiveness in industries requiring high-performance surface treatments.
