ExperimentalProcedure

TheSS-4dryfilmwasappliedtoasteelsubstratebyaspraycoatingmethod.ThesurfaceroughnessofthesubstratewasRa=0.6μm.Thethicknessofthedryfilmwas20μm.Thetribologicaltestswereperformedusingapin-on-disktribometer.Thepinwasatungstencarbideballwithadiameterof6mm.Theloadwasvariedfrom1to10N,andtheslidingspeedwasvariedfrom0.1to1m/s.Thetestswerecarriedoutunderdryslidingconditions,withoutanylubrication.

Thefrictioncoefficientwasmeasuredinreal-timeduringthetestsusingafrictionforcesensor.Thewearvolumewasmeasuredusinga3Dopticalprofiler.MicroscopicobservationswereperformedusinganSEMtoanalyzethewearmechanism.

ResultsandDiscussion

TheresultsshowedthatthefrictioncoefficientofSS-4dryfilmdecreasedwithincreasingloadandslidingspeed.Atlowloadsandslidingspeeds,thefrictioncoefficientwasaslowas0.05,indicatingagoodlubricationperformanceofSS-4dryfilm.Athighloadsandslidingspeeds,thefrictioncoefficientincreased,andthesurfacetemperaturerosesignificantly.Theincreaseinthefrictioncoefficientismainlyduetothethermaleffectandtheinteractionbetweenthecontactingsurfaces.

Thewearvolumeincreasedwithincreasingloadandslidingspeed.Thedominantwearmechanismwasadhesiveandabrasivewear.TheSEMobservationsshowedthatthewearmarksontheSS-4dryfilmsurfacewerecharacterizedbymicrocracks,ploughing,anddelamination.Thewearratewasfoundtobeproportionaltotheloadandslidingspeed,indicatingthatthewearmechanismisloadandspeeddependent.
