Abstract
The main features of high-voltage electric pulse consolidation (HVC) of refractory powder materials and the resulting unique capabilities of the method are considered. The electro-thermal processes of HVC at the contacts between powder particles and at the macroscale of the entire consolidated sample are analyzed. The results of experimental studies of the parameters of high-voltage electrical impulse action in the processes of consolidation of high-temperature powder compositions, high-voltage welding of dissimilar materials, as well as high-voltage discharges in liquid are presented. The results of measuring the intensity of thermal radiation of the investigated materials under high-voltage electrical impulse action, recorded by the method of pulse photometry using photodiode sensors, which, together with the Rogowski coil, are components of the measuring complex developed by the authors, are presented.
期刊介绍:
High Temperature Material Processes is an important international publication devoted to original and invited review papers on fundamental and applied re-search and new developments in materials processing and synthesis at high temperatures, especially under the plasma action as well as the treatment by laser, ion and electron beams. Processes of interest include (but not limited to) surface treatments, alloying, coatings production, nanostructures synthesis, welding, cutting, melting, re-melting and purification of metals, metallurgy (among them plasma metallurgy), powder densification, ultra-fine powder production, waste conversion and destruction. In addition, attention is paid to the development, description and study of experimental and industrial systems and devices for the implementation of high-technology plasma and beam processes. Thus, there is a broad range of coverage of experimental, analytical and numerical studies. High Temperature Material Processes will serve the needs of those who develop high temperature processes to produce materials with improved properties, surface treatments or coatings with given specifications, and will also promote connections between laboratories and industry.
