Effects of surface treatments and coatings on tribological performance of Ti–6Al–4V in the mixed fretting and gross slip regimes

摘要: Abstract Although titanium alloys are chemically resistant and have desirable mechanical properties, these materials known to experience high wear rates friction when they in contact relative motion with themselves or most other materials. In this study, titanium-containing MoS 2 Ti containing amorphous carbon coatings been applied Ti–6Al–4V discs were examined mixed fretting gross slip regimes against uncoated, NiPO 4 , MnPO coated AISI 52100 counterfaces. Experiments carried out at two different temperatures coefficients obtained for the various material pairs. Whereas smallest /Ti–MoS pairs both low temperatures, coupling is incompatible. On hand, /Ti–aC appears be a very compatible pair.
