Abstract

The aim of this study is evaluate two different techniques of modification of titanium surface and to compare the surface roughness levels, surface wettability and surface configuration of variously treated surfaces of titanium (commercially pure titanium grade I). Commercially pure titanium (Grade I) sheets of 0.2mm thick and 4.5mm diameter are used for this study. Blasting of titanium with Alumina, combined with Acid etching using Hydrofluoric acid, Hydrochloric acid and sulfuric acid. And Oxidation treatment is done with Sodium hydroxide, Surface roughness levels were measured with the help of surface profilometer and surface analyzer. Surface wettability is measured with help of contact angle measurement using light microscope and surface configuration was determined with the help of scanning electron microscopy. Scanning electron microscopic studies concluded that samples with alumina blasting followed by acid etching revealed uniform rough configuration of the surface.
