Abstract

The aim of this paper is to study the structure formation in the composite powder material "copper- Ti3SiC2" and to study erosion-resistance of tool-electrode made from this material by EDM of metal alloys. The influence of Ti3SiC2 content on the properties (porosity, hardness, strength, electrical resistance, erosion wear) of composite materials Cu-Ti3SiC2 was studied. The features of the structure formation of composition of materials during sintering is deintercalation of silicon from Ti3SiC2, formation of a solid solution of carbon-based titanium silicide Ti5Si3(C), small amounts of titanium carbide, silicon, and silicide TiSi2. Increasing the concentration of Ti3SiC2 in the composite material reduces conductive properties, increases hardness, strength and wear resistance of the electroerosion electrode composites for EDM. The new material was used as a tool-electrode for electrical discharge machining for the first time. It was determined that the relative erosion wear resistance of a tool-electrode of composite materials Cu-Ti3SiC2, containing 12.5 - 37.5 vol. % Ti3SiC2, in electrical discharge machining was 5 times higher compared to that of pure copper.
