Description

technical field [0001] The invention relates to the technical field of electric processing, in particular to a novel electrode composite electric processing device and a processing method. Background technique [0002] Compared with traditional metal materials, metal matrix composites have higher stiffness and strength; compared with silicon carbide-based materials, they have higher toughness and impact performance. Among metal matrix composites, aluminum matrix composites are the most widely used. Particle-reinforced aluminum matrix composites are composite materials in which aluminum or aluminum alloy is the continuous phase and ceramic particles are the second constituent phase. Aluminum matrix composites The performance depends on the characteristics, content, distribution, etc. of the matrix alloy and the reinforcing phase. Compared with matrix alloys, aluminum matrix composites have many excellent properties. [0003] The composition and structural characteristics of...
