Abstract:
The activities described in the paper are aimed at solving the problem of forming various articles from homogeneous metallic powders of copper and molybdenum, from a mixture of copper, titanium, and boron powders, and from a mixture of the copper powder with uniformly distributed particles of titanium diboride (up to 40 vol.%). The idea is to obtain compacts with the minimumchanges in the initial structure of the material and with high resistance to electric erosion under conditions of high currents. A method of electric-pulse sintering is used, where the compacting process is ensured with one capacitor discharge with a current density of $\le$10$^3$ A/mm$^2$ and sintering time of $\le$10$^{-4}$ sec. Conditions of sintering of powders pre-compressed by a pressure of several kilobars are studied. The density, microstructure, and phase composition of the sintered samples are examined. The erosion resistance of a Cu/TiB$_2$ porous nanostructural composite is tested on a model erosive plasma accelerator.
