ELECTROCHEMICAL BEHAVIOUR OF PHASES IN TITANIUM ALLOYS

Abstract

Abstract: The electrochemical behaviour,which is presented by means of anodic polarization curves.of the component phases in Ti and Ti alloys in aqueous solutions of fluorhydrie acid,chhnhydric acid and amber acid has been investigated.The results indicate that the electrochemical behaviour of the allloys depends upon the composition and the lattice type.The corrosion of x and x′phase in actire region and that of β phase in passive region are the dominant corrosion behaviour.

Key words: Ti alloy, electrochemical behaviour, polarization curve
