The effect of hydrogen on wear resistance of Ti-6Al-4V has been investigated in IN H{sub 2}SO{sub 4} at different polarized potentials. The morphology of debris and wear scars was observed in SEM and metallography. The contents of hydrogen in both wear debris and subsurface of specimen were determined by the gas chromatographic method and SIMS, respectively. The experiment shows that the wear losses may be partially controlled by cathode protection, but wear increases from over-protection. The unusual wear losses may be explained by hydrogen embrittlement of the Ti alloy because of hydrogen evolution on the specimen surface. 5 refs.
