Laser surface nitriding of titanium and a titanium alloy
Journal of Materials Processing Technology, 1992 Surfaces of titanium and titanium alloy IMI829 have been nitrided by laser melting in nitrogen and in a gas mixture containing various proportions of argon and nitrogen. The nitrided layers have been characterised with respect to their hardness, microstructure, chemical composition, corrosion properties and surface finish.

Nitriding phenomena in titanium and the 6Al-4V titanium alloy
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1960 Nitriding unalloyed titanium in purified nitrogen at 1,800° F produced a uniformly thick case that consisted of five distinct zones. The same treatment applied to a 6Al-4V titanium alloy resulted in a thinner nitride case that consisted of three zones and elongated nitride grains that penetrated into the core at approximately 45 degrees to the specimen

Selected fretting-wear-resistant coatings for titanium - 6-percent-aluminum - 4-percent-vanadium alloy [PDF]
A titanium - 6-percent-aluminum - 4-percent-vanadium alloy (Ti-6Al-4V) was subjected to fretting-wear exposures against uncoated Ti-6Al-4V as a baseline and against various coatings and surface treatments applied to Ti-6Al-4V.
