Abstract

The developed theoretical bases of search of new, perspective materials with the valuable physical and chemical properties, directed on creation of display electrodes have allowed to offer element nickel and an alloy on its basis - kovar (29NК), and also a polymer-composite material – carbon plastic, as materials for display electrodes. It is shown that criterion in a choice of materials is their solubility in mercury and corrosion firmness in working electrolytes which is in turn defined by structure and a structure of their crystal lattice, the physical and chemical properties, formed on a surface of the sample оксидных films and firm products of reaction. Influence of methods of mechanical, chemical and electrochemical preparation of a carbonplastical electrode working surface is studied and features of the processes which are passing thus on border are revealed has undressed an electrode-solution.
