Chemical etching of titanium samples

Periodica Polytechnica Mechanical Engineering, 2013
We studied chemical etching treatment on the surface of titanium implant materials, specifically 2 mm thick Grade 2 and nanoparticulate titanium discs, aiming to modify the surface roughness of samples. For chemical etching we investigated changes in reaction time on the surface (15-600 seconds). During the research we obtained the changes of thickness,
