Abstract

The aim of this work is to study the possibility of obtaining nanosized filamentary powders of alloys of metals of the iron group of a given size and shape. The results of experimental studies of the process of electrocrystallization in electrochemical double-layer system of filaments of an alloy of iron-cobalt. The conditions for obtaining nanopowders with different morphology. The model of particle growth of the alloy. On the basis of electron microscopic analysis produced a classification of filiform crystals grown at constant and pulsed currents. This method of obtaining powders has a number of advantages: availability of preparative and apparatus for performing synthesis, the ability to control the process of electrocrystallization, obtaining the necessary amount of powder of different shapes, not contaminated by impurities.

 

Keywords: electrocrystallization; nanopowder; whiskers; pulsating current; needle-like crystals.
