【 摘 要 】

Titanium is known for its strong affinity towards nitrogen. The metal forms a nitride form case of high hardness when the salt bath nitriding is carried out. The selection of Grade 2 Titanium and Grade 5 Ti6Al4V Titanium alloy, stands with the fact that CP Grade 2 Titanium is the most formable and corrosion resistant amongst the pure grades of Titanium and grade 5 alloy is biocompatible and also has excellent tribological properties. This research work attempts to solve the problem of galling by comparing the morphology of the nitride case produced in Commercially Pure Grade 2 Titanium and the nitride formations produced in the Titanium Ti6Al4V alloy through Salt bath nitriding for a time span of 24 hours. Salt Bath Nitriding imparts unique improvements in Roughness, Hardness and Wear resistance of the samples thereby widening the applications of the material.
