摘要：
In polymeric bearing applications it was found that the polymer tends to wear more quickly than indicated in laboratory wear tests. The reason has been attributed to the effect of loading conditions and the generation of fatigue surface cracks. The current study investigated the effect of single imposed vertical crack in the Nylon 66 surface upon its wear behaviour in dry and water lubricated sliding conditions. The polymer was tested under different static and cyclic loading parameters. There was consistent evidence of the effect of surface crack on the wear rate under static and cyclic loading conditions.
