The aim of work is to establish the regulurs of selective disolution of deformed, various geteregeneous level alloys and is to elaborate the theoretical method of a selective dissolution forecast these alloys by analizing energetic effect adsorption and disorption processes on the fhase interface by means of corrosion electrochemical methods. The method of investigation and equipments are quantum-chemical and corrosion-electrochemical (volt-ampere system "СВА-ИБМ" with rotating disk electrode, fatigue equipment "ИМА-5ЕК", computer PENTIUM-166). The quantum-chemical semi empirical cluster model for interaction of deformed alloys (-brass, Zn-5Al and Zn-15Al with components of an acid solution of sodium chloride is constructed. The parities of value of energy activation, heats of adsorption and leaving of ions different components alloys were found and were confirmed by experimental results, which testifi t hat the mechanical pressere intensificated selective dissolution of zinc. The mechanism of selective dissolution of modelling alloys was offered.
