Abstract

For the production of composite contact materials in high-voltage and heavily loaded switching devices, applying heat-proof components based on a mixture of powders of tungsten and 4% nickel (WN-4). Possibility of the electrochemical recycling is investigational authors - obsolete cores of armour-piercers for receiving such powders. Full text download
