Процессы, которые инициируются действием электрического тока (обзор)

Abstract

Under electric current action the complex powder-like system in the process of consolidation there are a few stages of technological process. Practical researches showed that on the initial stage of electrosintering process between particles sufficient terms are created for realization of process of electric disruption of dielectric layer. After it the matter of powder-like compact becomes electro-conducting in the areas of transition from one powder-like particle to other. On this stage a process is characterized by an unstationarity. It is related to statistical character of running the general number of pin areas and with passing of electric current on bridges, where physical and chemical transients are. It influences on the further process of compression.
