XXX et al. (USA) investigated the in-vivo oxidation of 120 retrieved XPE bearings.
The authors noted that oxidation has been reported in both annealed and remelted XPE retrievals and may change the material’s wear resistance.
Therefore they claimed that the effectiveness of these stabilization methods in preventing in-vivo oxidation and to forecast the future performance of XPE bearings requires the analysis of all types of XPE retrievals.
According to the authors, 50% of retrieved XPE showed an in-vivo oxidation.
The free radical concentration (FRC) was measured in retrievals of annealed XPE and ***antioxidant*** XPE.
