Abstract: Titanium grade 5 alloy is being very distinct because of light weight and higher strength. These alloys are extensively used in aerospace industries. Response of these Titanium alloys under different load level and speed level during contact is required to be studied. The literature survey indicates inadequate studies on effect of load and speed during relative motion. Experiments have been conducted using Pin-On-Disc test rig in laboratory to simulated field conditions. Two load levels of 1.5kg and 3kg and three speed levels of 500,1000 and 1500rpm were maintained during experiments. Pin surface have been studied under Scanning Electron Micrograph [SEM] for understanding wear behaviour. The coefficient of friction was found to be more sensitive to the speed of sliding. At speed of 1500 rpm, irrespective of normal load, two distinct sliding phases, i.e., phase I and phase II have been observed as sliding progressed. Oxidation of wear debris, at lower speed and phase I of sliding takes place.
