This paper is concerned with studying the tribocorrosion of CP-Ti and Ti 6Al 4V alloys used for biomedical applications and compare the results and then choose the best alloy. This research is divided into two parts. The first part is to characterize the alloys using XRD, OM, SEM, and XRF. The second part includes making a tribocorrosion test for the alloys (cathodic potential, anodic potential, and open circuit potential) using three different loads ( 1N ,2N and 4N ). calculating the coefficient of friction and the effect of the load applied to it, as well as calculating the lost weight resulting from the mechanical effect and the electrochemical effect during the test . Metal characterization methods (SEM, XRD,XRF and OM) showed that CP-Ti consisted of single phases ( α ) as expected and Ti 6Al 4V consisted of two phases α + β as expected (α -rich). The test showed that load has an effect on the coefficient of friction, as the coefficient increases with increasing load and as a result an increase in the lost weight. |
