Corrosion Behavior of Laser Nitrided Ti-6Al-4V Alloy: A Review

Abstract:

Article Preview

The titanium alloys-especially Ti-6Al-4V- are attractive materials because of their high specific strength and low density. But these alloys have poor surface properties such as wear and corrosion resistance for many industrial applications. Laser surface nitriding technique, has been the subject of considerable interest as a means of enhancing the surface performance of titanium alloys. In the present paper, the corrosion properties of laser nitrided Ti-6Al-4V alloy that have been reported by several researchers until now is considered. The microstructure changes, phase’s formation and the influence of laser processing parameters on them, in laser nitriding layers of Ti-6Al-4V alloy are investigated in different manners like SEM, TEM, XPS and XRD. At the end of this paper, the effects of laser nitriding on the corrosion behavior of Ti-6Al-4V alloy are reviewed.
