Optimization of Suitable Electrolyte for High Emittance coating on Titanium Alloy

Abstract

Titanium and it's alloys are used in the aerospace industry due to its light weigh, strength and ability to withstand extreme temperatures. Also titanium is as strong as Steel but much lighter, it is twice as strong as aluminum. It is nearly as resistant to corrosion as platinum. Titanium is used in dental implants due to its ability to Osseo integrate (an unusual ability by which titanium fuses with bone tissue through the titanium oxide layer on titanium metal). Titanium dioxide is relatively clear and has an extremely high index of refraction with an optical dispersion higher than diamond. Titanium dioxide is used extensively for paints as it is permanent and has good covering power. The present work involves optimization of the electrolyte composition in order to get a coating with high emissivity on titanium alloy using micro arc oxidation process. It also involves study of other parameters such as Thermo-optical properties, surface and characterization of the coating.
