I-Chemical polishing yinkqubo eqhelekileyo yonyango yendawo yensimbi engenasici.Xa kuthelekiswa neinkqubo electrochemical polishing, eyona nto iluncedo lwayo kukukwazi ukupolisha iindawo ezimile kakuhle ngaphandle kwesidingo somthombo wamandla we-DC kunye nokulungiswa okukhethekileyo, okukhokelela kwimveliso ephezulu.Ngokusebenzayo, ukupolisha kweekhemikhali akunikezeli nje kuphela umphezulu wokucoceka ngokwasemzimbeni kunye neekhemikhali kodwa kwakhona kususa umaleko womonakalo womatshini kunye noxinzelelo loxinzelelo kumphezulu wentsimbi.
Oku kubangela umgangatho ococekileyo ngoomatshini, onenzuzo yokuthintela ukubola kwendawo, ukuphucula amandla omatshini, kunye nokwandisa ubomi benkonzo yamacandelo.
Nangona kunjalo, ukusetyenziswa okusebenzayo kubangela imingeni ngenxa yeendidi ezahlukeneyo zensimbi engenasici.Amanqanaba ahlukeneyo entsimbi ecocekileyo abonisa ezawo iipateni zophuhliso lokuthotywa komhlwa, nto leyo eyenza ukuba kube nzima ukusebenzisa isisombululo esinye sokupholisha imichiza.Ngenxa yoko, kukho iintlobo ezininzi zedatha yezisombululo zentsimbi yensimbi engenasici.
Intsimbi engatyiwayo yokupholishwa kwe-electrolyticibandakanya ukumisa iimveliso zensimbi ezingenasici kwi-anode kwaye zibeke phantsi kwe-anodic electrolysis kwisisombululo se-electrolytic polishing.I-Electrolytic polishing yinkqubo ekhethekileyo ye-anodic apho imveliso yensimbi engenasici idlula iinkqubo ezimbini eziphikisanayo ngaxeshanye: ukubunjwa okuqhubekayo kunye nokuchithwa kwefilimu ye-oxide yensimbi.Nangona kunjalo, iimeko zefilimu yekhemikhali eyenziwe kwindawo ye-convex kunye ne-concave yemveliso yensimbi engenasici ukuba ingene kwimeko ye-passivated iyahluka.Ukuxinwa kweetyuwa zetsimbi kwindawo ye-anode ngokuqhubekayo kwanda ngenxa yokuchithwa kwe-anodic, ukwenza ifilimu eqinile, ephezulu yokumelana nomgangatho wemveliso yensimbi engenasici.
Ubunzima befilimu engqingqwa kwi-micro-convex kunye ne-concave surfaces yemveliso iyahluka, kwaye ukuhanjiswa kwe-anode micro-surface current ayilingani.Kwiindawo ezinoxinano oluphezulu lwangoku, ukunyibilika kwenzeka ngokukhawuleza, kubeka phambili ukuchithwa kwee-burrs okanye iibhloko ze-micro-convex kumphezulu wemveliso ukufezekisa ukugudisa.Ngokwahlukileyo, iindawo ezinoxinano olusezantsi zibonisa ukunyibilika kancinci.Ngenxa yosasazo olwahlukeneyo loxinaniso lwangoku, umphezulu wemveliso uqhubeka usenza ifilimu kwaye inyibilika ngamaxabiso ahlukeneyo.Ngexesha elifanayo, iinkqubo ezimbini ezichasayo zenzeka kwi-anode surface: ukubunjwa kwefilimu kunye nokuchithwa, kunye nesizukulwana esiqhubekayo kunye nokuchithwa kwefilimu ye-passivation.Oku kubangela imbonakalo egudileyo kwaye iphucuke kakhulu kumphezulu weemveliso zensimbi ezingenasici, ukufezekisa injongo yentsimbi engenasici yokucolisa kunye nokucokisa.
