等离子喷涂Fe基非晶复合涂层的磨损和腐蚀机制的研究（英文） Title:InvestigationonWearandCorrosionMechanismsofPlasmaSprayedFe-BasedAmorphousCompositeCoatings Abstract: TheaimofthisstudyistoinvestigatethewearandcorrosionmechanismsofplasmasprayedFe-basedamorphouscompositecoatings.Byunderstandingthedegradationmechanisms,wecanoptimizethecoatingpropertiesandenhancetheperformanceinvariousindustries.Theexperimentalanalysisinvolvedcharacterizingthecoatingmicrostructure,evaluatingwearresistancethroughslidingandabrasivetests,aswellasanalyzingthecorrosionbehaviorindifferentcorrosiveenvironments. Introduction: Fe-basedamorphouscompositecoatingshavegainedsignificantattentionduetotheirexceptionalmechanical,thermal,andcorrosionresistanceproperties.Thesecoatingspossessgreatpotentialforapplicationsinvariousindustries,suchasaerospace,automotive,andmarinesectors.However,thereisstillalackofcomprehensiveunderstandingofthewearandcorrosionmechanismsaffectingthesecoatings.Thisstudyaimstobridgethisknowledgegapandprovideinsightsintothedegradationmechanisms. Methodology: TheexperimentalstudyinvolvesthedepositionofFe-basedamorphouscompositecoatingsusingplasmaspraytechnology.Thecoatingsaredepositedonvarioussubstratestosimulatedifferentindustry-specificapplications.Themicrostructureofthecoatingsisanalyzedusingscanningelectronmicroscopy(SEM),energy-dispersivespectroscopy(EDS),andX-raydiffraction(XRD).Thewearresistanceofthecoatingsisevaluatedthroughslidingandabrasivetests,whichsimulatereal-lifewearconditionsindifferentindustrysectors.Additionally,thecorrosionbehaviorofthecoatingsisstudiedusingpotentiodynamicpolarizationandelectrochemicalimpedancespectroscopy(EIS)techniques.
