高重复频率光纤激光扫描除锈机理及实验研究的中期报告 Abstract： Theapplicationofhigh-frequencyfiberlaserinrustremovalhasattractedwidespreadattentionduetoitsadvantagesofhighprecision,highefficiency,andenvironmentalprotection.Inthispaper,weproposeahighrepeatabilityfiberlaserscanningrustremovalmechanismandconductexperimentalresearchonthismechanism. Introduction： Inthetraditionalrustremovalprocess,variousmethodssuchaschemicalrustremoval,mechanicalrustremoval,andthermalrustremovalareused.Thesemethodsnotonlyhavepoorremovalefficiency,butalsocausedamagetothesurfaceoftheworkpieceandposeasignificantthreattotheenvironmentandhumanhealth.Inrecentyears,withthedevelopmentoflasertechnology,laserrustremovalhasbecomeahotresearchtopic,andhigh-frequencyfiberlaserscanningrustremovalhasbecomethefocusofrelatedresearch. Mechanism： Thehigh-frequencyfiberlaserscanningrustremovalmechanismproposedinthispaperisbasedontheprincipleofabsorptionoflaserenergyonthesurfaceofthemetal.Whenalaserbeamirradiatesthemetalsurface,thesurfacetemperaturerisessharply,andthemetaloxidelayerevaporatesorcracks,therebyachievingthepurposeofrustremoval.Thehigh-frequencyscanningmethodensurestheuniformityandconsistencyofrustremovalbyscanningtheworkpiecemultipletimes. Experimentalresearch： Inthisresearch,a500Whigh-frequencyfiberlaserwasusedasthesourceofrustremoval,andtherustremovalexperimentwasconductedonasteelplatewithrust.Theexperimentalprocessconsistedofpre-treatment,rustremoval,andpost-treatment.Theresultsshowthatthehigh-frequencyfiberlaserscanningrustremovalmechanismhasahighefficiencyandcanachieveagoodrustremovaleffect,withoutcausingdamagetothesurfaceoftheworkpiece. Conclusion： Thehighrepeatabilityfiberlaserscanningrustremovalmechanismproposedinthispaperhastheadvantagesofhighefficiency,highprecision,andenvironmentalprotection,whichprovidesapromisingnewdirectionforthedevelopmentofrustremovaltechnology.Theexperimentalresearchalsoprovesthefeasibilityandeffectivenessofthismechanism.Inthefuture,furtherresearchwillbeconductedontheoptimizationofscanpar
