Indlela anodized aluminium

ekukhiqizweni aluminium izakhiwo kanye izingxenye ngenxa izakhiwo eziyingqayizivele le nto. It has isisindo ephansi ethize, amelana ezindaweni eziningi ezonakalisayo futhi kusetshenzwe kalula. Kodwa ukuphila isikhathi eside imikhiqizo kudingeka anodized aluminium.

Kungani idingeka

Phakathi nokuxhumana zensimbi ne oksijini emkhathini kwenzeka ngesikhathi kobuso namachibi topsheet. Lokhu kubizwa ngokuthi ukwakheka ifilimu oxide, okuyinto evimbela esiphelweni ngaphakathi nokugqwala metal.

Kuye impahla ebusweni namachibi inqubo lihlukile. Insimbi steel is cishe kwakhiwa ifilimu oxide, kodwa amatshe ayigugu (igolide, isiliva, platinum) bavikelekile ukugqwala. Aluminium kuthatha isikhundla maphakathi, ngakho isidingo ukudalwa yokufakelwa ifilimu. Lokhu kubalulekile ikakhulukazi uma womshini amafasitela kuyosebenza iphrofayli efanayo. Anodized aluminium olumelana zangaphandle sezulu izici okuyinto ingadala ukugqwala futhi ukulahlekelwa okusheshayo ukusebenza izakhiwo isakhiwo.

ubuchwepheshe

Ukuze yakha iphumelela airfoil ebusweni zokuzivikela ifilimu kudinga Anodizing aluminium. Ingqikithi inqubo itholakala ethwele molecule enye impahla okungukuthi livikela kakhulu imiphumela oxygen isakhiwo umkhiqizo. Ngaphezu kwalokho, kungenzeka ukuba eyayenziwe kufuthwe ungqimba oxide ngaphandle kwalokho nezinye izinsimbi.

Yimiphi indlela okudingeka ukufeza imibandela inqubo. Siqukethe izinyathelo ezilandelayo:

1. Preparatory.
2. Inqubo anodization.
3. ungqimba okubambelela.

Ukuze ngamunye wabo akhethiwe imishini ezifanele nezimpahla ezidingekayo. Ngenxa yalokho, kufanele uthole eliphezulu anodized aluminium. Lokhu kuyokunika ithuba ukusebenzisa iphrofayli ukwenziwa olungaphambili lwesonto kanye iwindi imiklamo.

I wokulungiselela isigaba

Umkhiqizo Kwamanzi kahle bahlanza kusuka uthuli, ukungcola kanye nemfucumfucu. Uma kukhona okungahambi noma umonakalo mechanical, basuke iqedwe ngisho phambi anodization. Ngaphezu kwalokho, kufanele ususe oxide ungqimba ubudala, ngaphandle kwalokho ngeke iphazamise kumiswa ifilimu iyunifomu zokuzivikela.

Ngemva machining (ukugaya nokuhlanganisa degreasing), iphrofayli kumelwe ibekwe ku-isixazululo ane-alikhali. Ukuze anodized kahle aluminium, kuzomele uqale ukwenza "etch" ebusweni. Ukwakhiwa semfene mikrokavern futhi kukhulisa indawo jikelele ungqimba zokuzivikela. ukucaciselwa okwengeziwe umkhiqizo wenziwa ikhambi ene-asidi. Lapho beqeda zonke izigaba aluminium kufanele ngokuphelele engahashazanga.

Anodizing

Ngemva edabula isigaba wokulungiselela kungenzeka ukuqala inqubo Anodizing. Ukuze wenze lokhu, imikhiqizo aluminium afakwa okugeza ekhethekile. Inqubo wenziwa ngosizo imishini crane (izakhiwo ezinkulu) noma ngesandla esebenzisa izintambo.

Mayelana okugeza design kufanele kuxoxiswane ngokwehlukile. Lunikeza obunamandla we steel thick-ngodonga insimbi lapho cathode 2 ibekwe. Iphrofayela ukucwiliswa ubuchwepheshe kumele kube yilawo angenza ukuthi electrolyte kule okugeza nabo yonke indawo komkhiqizo. Ngenxa sulfuric acid ketshezi ezinjalo kusetshenziswa, okuyinto ubeka ingcindezi ekhethekile ku ukuphepha zokukhiqiza. Uma umkhiqizo has a ukumisa eziyinkimbinkimbi, kungcono ukusebenzisa oxalic acid.

Ngemva iphrofayela ukucwiliswa electrolysis uqala ukwakha ungqimba zokuzivikela. ukujiya kwakho kuncike yokwakheka electrolyte, izinga lokushisa kanye ukuminyana zamanje. Ayanda sibalo yokugcina, elikhulu oxide ifilimu kwakhiwa phezu. Uma kuphelile ukushuba ungqimba ziyahlukahluka kusuka microns 2 kuya ku-7, kuye ngokuthi inqubo nemingcele.

ukulungisa

Nokho, ngalesi ayeke kusasekuseni ukuqagula Anodizing aluminium - kudingekile ukulungisa kwakhiwa ebusweni ungqimba. Kuzoba sokunamathisela isakhiwo ukungena nakwamanye amazwe lapho ngokushesha ngaphandle kokwelashwa exfoliates. Ngaphandle kwalokho, kusho ukuthi ayinaso izici ezithile zomkhathi ubulukhuni.

Fixing kungase kufezeke ngokubheja umkhiqizo ngendlela amanzi ahlanzekile alethwe isimo ngamathumba. Ngokusho kwenye i-surface ubuchwepheshe iphathwa nge umusi ashisayo. Kunoma ikuphi kukhona nokwenqatshwa ifilimu oxide nemisho lemagalagala yayo yamangqamuzana ne ebusweni aluminium.

Uma Ukuphrofayela esizayo ngeke ngesineke, awukwazi ukwenza ukuhlanganisa. Lapho usebenzisa ubuchwepheshe of the aviation powder, ifilimu uyovikelwa ngenxa ukwelashwa ukushisa.

Sithole ukuthi anodized aluminium. machining metal okunjalo - isiqinisekiso ngokumelene nokugqwala phezu umkhiqizo. Anodizing ubuchwepheshe njalo ukuthuthukisa, futhi namuhla ongakwenza Umdwebo imikhiqizo aluminium ngosizo ukusabela cathodic.
