The article describes the main characteristics of plasma technology designed for the production of metal powders, such as voltage, current, plasma-forming gas flow rate, plasma flow temperature. Based on experimental data and theoretical calculations, mathematical models are constructed to refine the defining characteristics, as well as to visualize the process. The mathematical model contains a spray chamber, an electrode rotation mechanism, a gas mixture supply unit, a plasma heating source, and a water cooling system for the chamber walls. The method of a rotating electrode with plasma heating (PREP) was used.
In recent years, the production of metal powder has become increasingly large-scale, and the requirements for the quality of the obtained powder are becoming stricter (fraction, sphericity, purity, flowability) - this is due not only to the increased demand for powder from standard industries of metallurgy, but also because the emergence and spread of additive technologies. In this article, a new method will be described for the production of metal powders, including titanium ones, the experimental results are given, namely, the value of currents, voltages and gas consumption in various operating modes. As a result of the experiments, a nominal operating mode was identified for one of the installation modules. Electric circuits and calculation model are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
