In this study Ti6Al4V alloy medical grade were subjected to surface chemical treatment. For this purpose cylindrical specimens similar to the standard sizes were machined and then were subjected to sandblast and acid etching. The acid etching process was performed at constant temperature and different times of 5, 10, 15, 20, 25 and 30 minutes. EDX and SEM evaluation were performed on the samples to evaluate the surface changes. SEM evaluations have shown that the best surface structure can be achieved by increasing the acid etching time to 25 minutes.
