PACS numbers: 65.40.gk, 65.40.gp, 68.35.Gy, 68.35.Md, 68.35.Np, 73.30.+y, 73.40.Jn

Based on the relations of nonequilibrium thermodynamics and mechanics of a deformed solid, physical-mathematical model of interface boundary of contacting metals is proposed for determining the energy characteristics of near-surface layers and contact potential difference. The interfacial-layers’ energy parameters (interfacial energy Wm, interfacial tension ?m, and energy of adhesive bonds Wad for contacting metals Cr, Fe, Al, Ni, Cu, Zn, Ti, Sn, Pb) are calculated. The internal contact potential difference ??Y (CPD) between metals under taking into account the energy parameters of interphase layer is evaluated. The comparison of the CPD calculation with similar known methods is carried out.

Key words: metals, interphase interaction, contact potential difference (CPD), energy parameters.
