... in slight scuffing, and a speed increase results in severe scuffing. Oil centrifugation has a strong effect on the loss of lubrication performance. Additional experiments under reduced quantity lubrication demonstrate the impact of the remaining oil on the survivability of gears facing the loss...

... is on the friction, wear, and scuffing characteristics. An interrupted wear test was conducted under lean oil conditions to study the scuffing behavior of plated Cr-diamonds coating (GDC) and diamond-like carbon coating (DLC). The findings reveal that DLC coatings exhibit superior tribological properties, displaying...

...Sheng Li; Ali Kolivand; Jing Wei This study establishes the critical temperature of scuffing for contacts of gears made of AISI 8620 steel alloy, lubricated by Dexron 6 oil. Through thermal mixed elastohydrodynamic lubrication modeling, experimental scuffing failures are simulated to determine...

...Vimal Edachery; V. Swamybabu; Anand Gurupatham; Manikandan Paramasamy; Satish V. Kailas Surface topography is a critical parameter that can influence friction and wear in engineering applications. In this study, the influence of surface topography directionality on seizure and scuffing initiation...

... contact length (CACL) in the sliding direction promotes the surface temperature rise, reducing the scuffing resistance performance. It is noted that the prediction of better SRP of Case IX than Case I 1 agrees with the experimental observation in Ref. [ 11 ]. The combination of peak-to-peak asperity...

...R. W. Snidle; A. K. Dhulipalla; H. P. Evans; C. V. Cooper Scuffing experiments were conducted using 76 mm diameter disks both with and without a metal-containing, carbon-based hard coating. The operating conditions in the experiments were severe with sliding speeds up to 16 m ∕ s and maximum...
