Abstract:
An equation for the surface tension isotherm is proposed. This equation is applied to calculate the isotherms of surface properties of binary metallic systems of $p$-metals. It is shown that, as in the case of binary systems of alkali metals, the proposed equation makes it possible to describe the isotherms of surface tension, adsorption, and surface concentrations with high accuracy in the entire concentration range, regardless of the degree of ideality of the system. It has been established that information on the surface tension of pure components and two melts of certain compositions is sufficient for calculating the surface characteristics and parameters of binary systems. For binary systems of ideal and regular solutions, good agreement is obtained between the results of calculations by the proposed and traditional methods, while for systems that are far from ideal, there is a significant discrepancy between the results, which the authors attribute to obtaining more accurate results by the proposed method.
