Fretting wear behaviour of machined layer of nickel-based superalloy produced by creep-feed profile grinding
文献摘要：
Fretting wear has an adverse impact on the fatigue life of turbine blade roots.The current work is to comparatively investigate the fretting wear behaviour of the nickel-based superalloy sur-faces produced by polishing and creep-feed profile grinding,respectively,in terms of surface/subsur-face fretting damage,the friction coefficient,wear volume and wear rate.Experimental results show that the granulated tribolayer aggravates the workpiece wear,while the flat compacted tribolayer enhances the wear resistance ability of workpiece,irrespective of whether the workpiece is processed by polishing or grinding.However,the wear behaviors of tribolayers are different.For the polished surface,when the normal load exceeds 100 N,the main defects are crack,rupture,delamination and peeling of workpiece materials;the wear mechanism changes from severe oxidative wear to fatigue wear and abrasive wear when the loads increase from 50 to 180 N.As for the ground surface,the main wear mechanism is abrasive wear.Particularly,the ground surface possesses better wear-resistant abil-ity than the polished surface because the former has the lower values in coefficient friction(0.23),wear volume(0.06 × 106 pm3)and wear rate(0.25×10-16 Pa-1).Finally,an illustration is given to char-acterize the evolution of wear debris on such nickel-based superalloy on the ground surface.
