Description
technical field [0001] The invention relates to an electric spark deposition equipment for the inner wall of a rotary part. Background technique [0002] EDM deposition is developed on the basis of the basic principles of EDM. Using the polarity effect phenomenon in EDM, the tool electrode material is deposited on the surface of the workpiece, and the workpiece thus obtains high hardness, high wear resistance, and high fatigue. Strength and special performance surfaces such as high corrosion resistance and oxidation resistance. The EDM process is now widely used in the surface strengthening of mechanical parts in industries such as tools, molds, cutting tools, agricultural machinery, military industry, medicine, automobiles, food, mining, and metallurgy, as well as the surface repair of failed parts. This process can truly realize the metallurgical bonding between the coating and the substrate, and at the same time keep the temperature of the substrate at room temperature, ...
