Ti-6Al-4V is considered to be the most important and useful alloy in the aerospace industry and many other applications. It has good mechanical properties as well as lower machining properties, especially in traditional drilling processes. In the previous study, ultrasonic assisted plasma oxidation grinding (UPOG) had been reported. This technology showed better material removal ability for Ti-6Al-4V. In this study, in order to investigate the material removal process for ultrasonic assisted plasma oxidation grinding (UPOG), scratching test was carried out with plasma oxidized samples. For the purpose of comparison, Ti-6Al-4V sample was also probed under similar conditions. This study has clearly demonstrated that the nature of plasma electrolytic oxidation present in the mechanism of deformation or material removal during nanoscratching test. During the test the deformation was distinctly captured with a high speed camera.
