Lomovskii, V. Maly, D. Dudina, M. Korchagin, A. Anisimov, G. Shvetsov, V. Boldyrev, J. Kim, Y. Kwon] A procedure is described for producing nanocomposite TiB2/Cu powders containing up to 57 vol % TiB2. Using shock compression of composite powders, we have prepared electrode materials offering enhanced electrical erosion resistance at high arc discharge currents. The effect of titanium diboride nanoparticles embedded in the copper matrix on the erosion behavior of the nanocomposites is examined. The nanoparticles are shown to suppress the copper droplet entrainment during the service of the electrode. TiB2/Cu nanocomposite electrodes containing more than 10 vol % TiB2 retain their shape and dimensions in the course of electrical erosion tests and offer enhanced service life.
