摘要: Abstract The interactions of a gaseous phase with liquid metallic surface are analysed in terms tension, adsorption and chemical reactivity. It is shown that thermodynamic equilibrium considerations not sufficient to interpret tension measurements especially at high temperatures, diffusion the vapour must also be considered. Surface isotherms discussed models allowing calculations maximum values presented. These particular interest when dealing systems forming very stable oxides. influence quantities on reactivity by means classical reasoning. One main results presented here reactions favoured bulk may take place surface, where presence excess free energy term favour another reaction, thermodynamically impossible phase.
