Исследование влияния добавок порошков Ni и Co на активацию процесса спекания тугоплавких металлов W и Mo

Abstract

The results of the study of the processes of pressing and sintering mixtures of the coarse powder of tungsten alloyed with nickel, with the addition of nanosized electroexplosive tungsten powder and powder charge based on nanosized tungsten powder containing nanoparticulate additives nickel. It is shown that the addition of up to 10 wt. % Tungsten nanopowder to activate the process of sintering of coarse agglomerates. The addition of nickel nanopowder undoped tungsten powder in an amount up to 1 wt. % More effectively activates the process of sintering than prior alloying tungsten with nickel powder. The influence of the content of nanopowder additives on structure and properties of the sintered material. Keywords: nanopowder, tungsten, molybdenum, nickel, cobalt, activated sintering.
