“…Depending on its direction, the electric current can have opposite effects on the CM process [6]. This is explained by the fact that the term on the right-hand side of equation (7), the sign of which is determined by the sign eв * , can make a diametrically opposite contribution to the magnitude and direction of the total flow in в (similar conclusions can be drawn in relation to а). In accordance with this, the process of electrotransfer during CM proceeds in two different modes:…”

Electric current has a significant effect on the transfer of matter in liquid layers that grow during contact melting. Depending on the direction of the current, both an increase and a decrease in the rate of contact melting can be observed. In this case, the growth of liquid interlayers does not obey the well-known parabolic law, in contrast to the usual (current-less) contact melting in a nonstationary diffusion mode and other diffusion processes. The paper considers the question of the influence of direct electric current on the concentration distribution in the melt formed during contact melting, as well as on the process of movement of interphase boundaries. A solution is obtained for the diffusion equation for a liquid layer growing in the process of contact melting in the presence of a constant electric current in the system. It is shown that the concentration distribution curves and their gradients for the two modes of the process under consideration (accelerating and decelerating) will have a rather different form, while the movement of the interphase boundaries occurs according to a complex law.

“…The samples of melting solid phases at CM are known to be located in a vertical position [7]. We will assume that solid phase 1 is the upper sample, which, according to the experimental conditions, should have a slightly lower density than the lower one (to prevent convection in the melt).…”

“…In the second case, with some limiting exposure, the growth of the liquid layer practically stops. This phenomenon serves as a convenient and illustrative method for studying ET in melts; it allows one to determine the effective charges of the components [11,12]. This paper discusses the main laws of the process of ET with a non-stationary CM [1], studies the effect on its parameters of the degree of difference of some physicochemical characteristics of the components of the melt [11][12][13][14].…”

The theoretical foundations of the process of electric transfer (ET) in melts growing during contact melting (CM) of binary systems are considered. It is shown when the modes of this process will be carried out-speed-up and speed-down. It has been established that electro transfer makes an additional contribution to the magnitude of the rate of macroscopic flow (determined by the displacement of inert tags), due to the inequality of the partial diffusion coefficients of the melt components. The electric current passing through the liquid layer, formed by the CM, can have a very significant impact on the rate of its growth. Depending on the direction of the current, both increase and decrease in the speed of the CM can be observed. The paper also discusses the main regularities of the ET process at a CM, studies the effect on its parameters of the degree of difference in some physicochemical characteristics of the melt.

“…In this case, the direction of the current in them was the opposite. This condition is due to the fact that due to the difference in the effective charges [4] of different metals, depending on the polarity of the electromagnetic field, contact melting is accelerated or slowed down. The result is determined by the so-called "integral criterion of electric transfer" given in [1][2][3][4][5].…”
