Methods: chronopotentiometry, gravimetry, spectrophotometry, impedance, X-rays analysis, electrothermography, microphoto, and other. Results: The physico-chemical regularities of ionization copper, aluminium and their alloys in aqueous and organic-aqueous media are established. The basic stages of ionization, influence of a ratio of components in alloys both solutions on kinetics and mechanism of anodic dissolution are determined. The new representations about the nonlinear equations electrochemical kinetics are of-fered which permit to determine energy of activation of a limiting stage of electrode reaction in impedance measurements executed at different temperatures. The influence of temperature and structure of solutions on thermodynamics of crown-complexes of K is investigated. The researches of discharge kinetics of Ge (4) - and Al (3) - coordination compaunds in the organic solvents of a different nature, which results are a basis of creation of technological conditions of creation of a polylaeric system Nb-Ge-Al, are carried out. The researches of kinetics of process of reduction of tin on dielectrics according to dis-mutation reaction are carried out. The method of the production of the gauge for revealing and control of contents of the donor-acceptor gases and vapors of organic substances and their mixtures is developed. Area of application: the results of work can be used in mechanical engineering and in-strument making for development of technologies of processing of metals and alloys, creation of superconducting under at high-temperature layers both gauges for revealing and control of gases, organic connections and their mixtures.
