Микроструктура и свойства мембранных сплавов системы V-Ti-Ni

Abstract

Alloys based on vanadium having bcc structure are considered as an alternative to palladium membrane alloys for hydrogen filtering. The advantages of vanadium alloys are relatively high hydrogen permeability and low prime cost. Both bulk and surface characteristics of the membrane alloys influence on filtering efficiency. The alloys of V-Ti-Ni system were investigated by means of XRD, SEM, XPS and hydrogen permeability techniques.
