The electrochemical and corrosion properties of ВНМ-3-2, ВНЖ-95 alloys and their components has been studied. The chemical and phase composition of passive layers using x-Ray diffraction (method θ-2θ) and layers grazing incidence geometry as well as termogravimetric method bas been tested. Anodic treatment influence on surface morphology has been determined. The composition and solution concentration influence on dissolution rate under the drilling operation has been determined.
