Ukucoca nge-Electropolishing vs. Passivation

Xa kufikwa ekugqityweni kwentsimbi engagqwaliyo, ezimbini zeenkqubo ezixutyushwa kakhulu yi-electropolishing kunye ne-passivation. Zombini iindlela zonyango ziphucula ukumelana nokugqwala kunye nomgangatho womphezulu wentsimbi engagqwaliyo, kodwa zifezekisa oku ngeendlela ezahlukeneyo kakhulu. Ukuqonda umahluko phakathi kwe-electropolishing kunye ne-passivation kubalulekile kwiinjineli, abavelisi, kunye neengcali zokuthenga abafuna ukuqinisekisa ukuqina kwemveliso, ukusebenza, kunye nokuthobela imigangatho yoshishino.

Eli nqaku libonelela ngothelekiso olunzulu phakathi kwe-electropolishing kunye ne-passivation, ligubungela iinkqubo zazo, izibonelelo, usetyenziso, kunye nezinto ezibalulekileyo eziza kukunceda ukhethe indlela efanelekileyo yokugqiba.

Yintoni i-Electropolishing?

I-Electropolishing yinkqubo ye-electrochemical esusa umaleko omncinci wesinyithi kumphezulu wentsimbi engagqwaliyo. Ngamanye amaxesha ibizwa ngokuba yi-"reverse plating." Endaweni yokufaka izinto, inyibilikisa iincopho ezincinci kumphezulu wesinyithi, idale ukugqitywa okugudileyo nokukhanyayo.

Inkqubo yokupholisha nge-Electropolishing

  1. Inxalenye yentsimbi engagqwaliyo intywiliselwa kwibhafu ye-electrolytic equlethe umxube wee-asidi (ngokuqhelekileyo i-sulfuric kunye ne-phosphoric).

  2. Kusetyenziswa umsinga othe ngqo, nto leyo eyenza i-workpiece ibe yi-anode.

  3. Ukungahambi kakuhle komphezulu kuyanyibilika ngokukhethekileyo, kwenze umphezulu ube kumgangatho ongaphantsi kakhulu.

  4. Isiphumo kukuba umphezulu ogudileyo nokhazimlayo ophucukileyo nokumelana nokugqwala.

Iingenelo ze-Electropolishing

  • Ukumelana Nokugqwala Okuphuculweyo:Ngokususa izinto ezingcolisayo kumphezulu kunye nokuthambisa imingxunya emincinci, ukupolisha nge-electro kwandisa ukumelana kwendalo kwentsimbi engagqwaliyo.

  • Ukuphuculwa kokuCoca:Ukugqitywa okugudileyo kunciphisa iindawo apho iintsholongwane kunye namasuntswana anokuqokelelana khona, nto leyo eyenza ukuba ibe yeyona ifanelekileyo ukusetyenziswa ngococeko.

  • Inkangeleko yoBuhle:Yenza ukugqitywa okukhanyayo nokukhanyayo okuphucula inkangeleko yemveliso.

  • Ukungqubana okuncitshisiweyo:Umphezulu ogudileyo unciphisa ukungqubana kwiindawo ezihambayo.

  • Ubomi Bokudinwa Obude:Ii-micro-cracks kunye ne-stress concentrators ziyancipha, nto leyo eyandisa ubomi benkonzo.

Yintoni iPassivation?

I-Passivation lunyango lwekhemikhali oluphucula umaleko wendalo we-oxide okhuselayo wentsimbi engagqwaliyo ngaphandle kokususa izinto ezininzi. Le nkqubo ayitshintshi ubukhulu okanye ukugqitywa komphezulu wesinyithi, kodwa iphucula ukumelana nokugqwala.

Inkqubo yokuPhumla

  1. Inxalenye yentsimbi engenasici icocwa kakuhle ukuze kususwe ioyile, igrisi kunye nesikali.

  2. Ifakwa kwisisombululo se-asidi ye-nitric okanye i-citric acid.

  3. I-asidi isusa i-iron ekhululekileyo kumphezulu ngelixa ivumela ifilimu ye-oxide etyebileyo kwi-chromium ukuba ivele.

  4. Imveliso yokugqibela inomaleko ophuculweyo ongakwaziyo ukumelana nokugqwala.

Iingenelo zePassivation

  • Ukuphucula Ukumelana Nokugqwala:Yomeleza umaleko we-chromium oxide, nto leyo eyenza isinyithi simelane ngakumbi ne-oxidation.

  • Akukho tshintsho kwimilinganiselo:Ekubeni i-passivation ingasusi izinto, ukunyamezelana okuchanekileyo kuyagcinwa.

  • Isebenza kakuhle emalini:Akukho nzima kakhulu kune-electropolishing, nto leyo eyenza ukuba kube lukhetho olungabizi kakhulu.

  • Ukuthobela iMigangatho:Ihlangabezana neemfuno ze-ASTM A967, AMS 2700, kunye nezinye iimfuno zoshishino.

  • Ukuguquguquka:Ifanelekile kwiindidi ezahlukeneyo zentsimbi engagqwaliyo kunye nokusetyenziswa kwayo.
