Critical review on different burnishing processes of Ti-6Al-4V Alloy

Abstract

Titanium and its alloys are the most commonly and most widely used due to its significant properties like good biocompatibility , good tensile strength , low density , and good creep property up to 300 degrees centigrade .It is used in the major engineering fields like civil engineering , nuclear engineering , aerospace engineering etc. Surface finish of the titanium material plays a prominent role in influencing its functional characteristics like wear resistance, fatigue strength, corrosion resistance and power loss due to friction. In normal machining methods like turning, milling or even classical grinding can’t meet the desired surface finish. To overcome this one of the method employed is burnishing, which is very simple and effective method for improvement in surface finish and can be carried out on lathe machine. The latest innovate technique used in the burnishing is the cryogenic burnishing in which the liquid nitrogen is supplied as the coolant. This work deals with study of different burnishing processes of titanium alloy Ti-6Al-4V.
