The friction and wear behavior of Cr3C2-25NiCr-coated brake disc (CD) and the sliding against the commercial brake pad were examined on a laboratory-scale disc-pad dynamometer and the findings were compared with those of reference brake disc (UCD). The coating was deposited by means of the HVOF process on a grey cast iron (GCI) substrate. Braking tests were performed according to the SAE-J2430 test standard. The as-sprayed coating was characterized for their microstructure and phase constitution by SEM/EDS and XRD. The results reveal that the coefficient of friction (COF) of CD and UCD varies between 0.42-0.57 and 0.44-0.62, respectively. The Cr3C2-25NiCr-coated brake disc was found to have exhibited a comparable COF and lower wear loss to the reference brake disc. The addition of a ceramic phase to the brake disc coating played an important role in reducing the COF to an acceptable range and improving the sliding wear resistance of the brake pair.en10.1142/S0218625X21500979info:eu-repo/semantics/closedAccessBrake DiscBraking EffectivenessCeramic CoatingWearSprayed Cr3c2-Nicr CoatingsSliding Wear BehaviorFriction BehaviorHeat-TreatmentHot CorrosionHvofTemperatureResistanceMicrostructureParametersArticle2810Q4WOS:0007056297000112-s2.0-85110747095Q3
