Abstract：To investigate the effect of enhanced grinding target distance on the friction and wear properties of GCr15 bearing steel,friction and wear experiments were conducted on GCr15 bearing steel processed at different target distances(90 mm and 150 mm)using a friction testing machine model M2000.The results indicate that the surface friction performance of GCr15 bearing steel has been improved after strengthened grinding treatment.Although the friction performance of the bearing steel sample with a target shooting distance of 150 mm has been improved,the fluctuation range of the friction coefficient during the stable wear stage is comparable to that of the friction coefficient without strengthened grinding treatment,both of which are 0.075.However,the fluctuation range of the friction coefficient during the stable wear stage of the bearing steel sample with a target shooting distance of 90 mm is only 0.03.Therefore,the friction performance of the sample with a target shooting distance of 90 mm is better.The wear performance is also better for samples with a target shooting distance of 90 mm;With the increase of the enhanced grinding target distance,the friction and wear performance of GCr15 bearing steel initially becomes increasingly excellent.However,as the target distance continues to increase,the friction and wear performance of GCr15 bearing steel will gradually deteriorate.Therefore,in order to obtain GCr15 bearing steel with better friction and wear performance,the target distance can be taken in the range of 60-120 mm.
