摘要
This article is devoted to the calculation of thermodynamic properties (mass density, enthalpy and specific heat at constant pressure) and transport coefficients (viscosity, electrical conductivity, thermal conductivity and combined diffusion coefficients) of mixtures of argon and aluminum, iron and copper vapour at atmospheric pressure. Data are presented for the temperature range 300 to 30 000 K, for different concentrations of the metal vapours. The dependence of the properties on metal vapour type and concentration are discussed. Mixtures of argon and metal vapour occur in the arc welding and in other plasma applications. Tabulations of the data are presented, and will be of use in computational modelling of such applications.
