Purpose: In this given work we consider a method CVA that at on one polarization curve allows us to trace the process of formation of the oxide film on the metal surface (anodic part of the curve), while the cathodic part of the curve to estimate the phase composition and its resistivity. Design/methodology/approach: Anodic polarization of metal surfaces in alkaline solutions used for obtaining oxide nanolayers with certain functional properties. To control the process of obtaining nanofilms apply a variety of physical, physicochemical and electrochemical methods. Findings: Theoretical analytical expressions describing the kinetics of growth of the oxide layers are supported by experimental studies of anodic polarization of Pb in alkaline solution. Research limitations/implications: A special place among those methods takes Local Electrochemical Analysis (LEA), allowing localizing electrochemical process at any given point on the surface. Originality/value: Originality of this work is study of the oxide layers on metals by local electrochemical analysis.
