- W2948598906 abstract "The main requirement for powders for additive 3d technologies is the spherical shape of the particles. Such particles are most compact in a certain volume and provide fluidity of the powder composition in the material supply systems with minimal resistance. In addition, the powder must contain a minimum amount of dissolved gas. The microstructure of the powder should be uniform and fine (with a uniform distribution of phase components). Based on the features of methods for producing spherical powders to obtain spherical granules of regulated grain, the technology of electroerosion dispersion, characterized by relatively low energy costs and environmental cleanliness of the process, is proposed. The main advantage of the proposed technology is the use of waste as raw materials, which is much cheaper than the pure components used in traditional technologies. In addition, this technology is powder, which allows powder-alloys. To develop technologies for the reuse of electrical erosion powders and to evaluate the effectiveness of their use, complex theoretical and experimental studies are required. The aim of this work to study the microhardness of the additive products of the electrical discharge machining of cobalt powders. For the proposed studies selected waste cobalt alloy brand CHMS CELLET. Butyl alcohol (butanol-1) was used as a working liquid. To obtain the cobalt powders used for the installation of AED dielectric materials. Dispersion parameters: voltage 100 V, capacity 48 UF, pulse repetition rate 120 Hz. According to the results of the research, it was experimentally established that the microhardness of additive products obtained from electroerosion powders with an average particle size of 52.5 µm is 5.7 GPA." @default.
