Description
Summary:The presented research work exhibited the experimental outcomes of the thermal oxidation process adopted for the surface modification of titanium alloy grade 2. It revealed the oxidation process kinetics of the titanium substrate within a specified temperature range of 600–800 °C, over time duration of 1/3 h to 72 h. An incremental change in mass of the specimen (titanium grade 2) was observed over an oxidizing temperature of 800 °C. Surface morphology as well as topography of the oxidized surface was investigated gently. Oxide film deposited over titanium substrate was observed to be comparatively larger at 600 °C as compared to 700 °C and 800 °C. Very fine and homogenized oxide particle deposition was observed at comparatively higher temperature. XRD analysis revealed that titanium oxide (TiO 2 ) presented in its crystallized form (rutile) and Ti 3 O was the prevalent form of oxide at moderate temperature range (600–700 °C), whereas at higher temperature of 800 °C, only rutile form of titanium oxide (TiO 2 ) was observed. After thermal oxidation of titanium alloy, tribological test was performed and it was observed that oxidized surface offered anti-wear strength to the titanium alloy, especially in case of abrasive wear. Volumetric wear reduction from 48% to more than 60% was evaluated for oxidized surface at temperature of 600 °C and 700 °C, respectively.
