In this project, Ti13Zr13Nb alloy was investigated in term of surface pre-treatment using two different types of acids, i. e. H2SO4 and Kroll s etchant solutions. Prior to etching, all substrates were cut, polished and blasted at identical conditions. Al2O3 abrasive particles of 150 m mean grain size were used to blast. Consequently, substrates were etched using two different acid solution (H2SO4 66% and Kroll s etchant) at three different temperatures (25?C, 45?C, 60?C) and varied times (10 s, 20 s, 30 s). Surface morphologies of etched substrates were evaluated under Field Emission-Scanning Electron Microscope equipped with Energy Dispersive Analysis X-ray (EDAX) and Atomic Force Microscopy (AFM). Surface roughness of treated samples were measured using the surface roughness machine. Finally, Kroll s etchant with 30 seconds and 45?C considers the best condition for providing surface roughness, at 400 nanometer (Ra) which is believed as good surface prior to PVD coating.
