A study of the corrosive wear of Ti-6Al-4V in acidic medium

The corrosive wear behaviour of Ti-6Al-4V was examined using a pin-on-disc wear device and potentiostat in 1N H 2SO 4 at different polarized potentials. The morphology of the debris and wear scars was investigated using scanning electron microscopy and metallography. The hydrogen content in both the...

Description
Summary:The corrosive wear behaviour of Ti-6Al-4V was examined using a pin-on-disc wear device and potentiostat in 1N H 2SO 4 at different polarized potentials. The morphology of the debris and wear scars was investigated using scanning electron microscopy and metallography. The hydrogen content in both the debris and the subsurface of the specimen was determined using the inert gas fusion method and secondary ion mass spectrometry respectively. The experiment shows that the wear losses may be partially controlled by cathodic protection but wear increases with over protection. The unusual wear losses can be explained by hydrogen embrittlement of the titanium alloy because of hydrogen evolution on the specimen surface.
