Wear and Corrosion Behaviour of Wire Electrical Discharge Machined Ti-6A1-4V alloy

Abstract

Abstract The objective of the current research work is to study the wear and corrosion behavior of Ti-6Al-4V ELI alloy. WEDM is preferred over conventional machining for Ti alloys, as they are hard-to-machine materials. Wear and corrosion tests were performed using wear and friction monitor (Ducom Model TR20-LE) and electrochemical workstation (Autolab PGSTAT204) respectively. SEM and EDS were also carried out on each sample for evaluating the surface morphology and to know the exact composition of the material. WEDM rough and trim-cut modes improve the surface hardness of Ti-6Al-4V ELI alloy and hence affects their c.o.f. and wear rates. The outcomes of the present research work promote WEDM trim-cut mode over rough-cut mode because it results in lower values of c.o.f., wear and corrosion rates.
