Abstract:
With the increasing integration of seawater hydraulic components, much attention has been paid to the tribological characteristics of PEEK bidirectional sliding against AISI630 tribopair. In the study, a bidirectional wear model based on Inverse Gaussian (IG) process is proposed based on bidirectional wear experiment. Impact wear occurs when the tribopair changes the motion direction. Through analysing the wear process and worn surface morphology of PEEK against AISI630 tribopairs, it is found that the impact wear would accelerate the formation and uniform distribution of PEEK transfer film, and the increase of reversal frequency can improve the tribological characteristics of the bidirectional tribopairs. The IG model considering the reversal impact can accurately illustrate the performance degradation path of actual impact wear.
