Abstract

Abstract: A short review of a porous materials production from the powders of titanium, niobium and tantalum with a high-voltage discharge current is presented. The experimental dependences of bending strength, porosity, specific electrical resistance, radial and axial shrinkage from the sizes of particles of the examined powders and from the parameters of the electric discharge are given. The maximum correlations of the diameters and the length of the experimental samples of porous powders are stated. The examples of perspective applications of produced porous materials in the manufactured articles of electronics and medicine are shown. Highlights: Proposed method for consolidation of hard metals powder through high-voltage discharge Represented structured and physical properties of obtained porous materials Based on the method, samples of titanium medical implants were represented. Also samples of anode niobium and tantalum MOS capacitors were manufactured.
