Notes:
In this study, the effect of thermal oxidation on the high cycle rotating bending fatiguebehavior of Ti6Al4V alloy was investigated. Oxidation, which was performed at 600°C for 60 h inair, considerably improved the surface hardness and particularly the yield strength of the alloywithout scarifying the tensile ductility. Unfortunately, the rotating bending fatigue strength at 5x106cycles decreased from about 610 MPa to about 400 MPa upon oxidation. Thus, thermal oxidationleaded a reduction in the fatigue strength of around 34%, while improving the surface hardness(HV0.1) and yield strength 85 % and 36 %, respectively
