Corrosion and Electrochemical Behavior of β-W CVD Coatings in NaCl Solution

Abstract

The paper presents the results of a study of the corrosion-electrochemical behavior of coatings based on the metastable phase of tungsten β-W obtained by chemical vapor deposition from fluorine-containing media in a neutral medium. It is shown that the corrosion nature of coatings based on β-W is fundamentally similar to that of the coatings based on α-W, but the β-W based coatings, due to a high stress state, show increased rates of corrosive dissolution.
