Iifilimu ze-anodic zingasetyenziselwa inani lezityalo zokuziqhenqa, mhlawumbi ngeengubo ezinokubumba ezinokubamba idayi okanye ngeengubo ezibonakalayo ezibonakalayo ezongeza imiphumo yokuphazamiseka ukubonisa ukukhanya.
Omnye umzekelo wezinto ezilandelayo zixhobo ezisetyenziswe ngabaqhubi beebhasi okanye iimpahla ukuze zibonwe ebusuku.
Indlela iAnodizing iyenzeka ngayo
Inkqubo yokudala le ngubo yokukhusela i-oxide iphumelele ngokukhenketho.
Inxalenye yesinyithi kufuneka iphathwe-ngokuqhelekileyo i- aluminium- yokuqala ibanjelwe kwisisombululo se-electrolytic kunye ne-cathode. Xa i-current isedluliselwa kwisisombululo se-asidi i-hydrogen ikhutshwa kwiifom ze-cathode kunye ne-oksijini kummandla we-anode. Oku kubangela ukuba ifilimu yenkampani ye-oxide iyakhula phezu kwendawo ephathwa ngayo.
Ngokuxhomekeke kwisicelo sokugqibela kunye nenkqubo yokugcoba esetyenzisiweyo, uhla lwe-oxide luyakwandiswa kakhulu. Ingqimba engakhula kwisahlulo se-aluminium sinokuba ngaphezu kwama-100 ngamaxesha anqamle njengendawo ye-oxide eyobe ikhona kwintsimi ye-aluminium ebonakalayo kuphela kwi-oksijini.
Ukuqonda ngokuqhelekileyo kubonisa ukuba ngenxa yokuba inxalenye yensimbi iphathwa i- anode kule yesekethe ye-electrolytic le nkqubo ichazwa ngokuthi 'i-anodizing'.
Ingxenye ye-aluminium e-aluminium kunye ne-aluminium engxenyeni ye-aluminium yinto eninzi kwaye iyanxiba ingxowankulu kunezinto ezingaphathwa. Ziyakhusela nokulwa ne-galling. Ukuguga kunxiba kubangelwa ukutshatyalaliswa xa iinxalenye ezimbini zezinto ezifakwe zixutywe kunye.
Isiphumo sokuphela kukuba iinxalenye ezigcotyiweyo zinokuhlala ixesha elide kunokuba zingekho iinxalenye.
Anodizing Aluminium
Ngoxa i-anodizing aluminium ivumela ukuba isinyithi sigcine imbonakalo yayo yendalo, i-pores kwinqanaba le-oxide elikhuselayo linokunceda ekuboneleleni ngokubhekiselele ekubambeni kwepeyinti kunye ne-glues.
Ngelixa iindidi ezahlukahlukeneyo, eziquka i- titanium , i-hafnium, i- zinc , ne- magnesium , zingakhuselwa ngokusetyenziswa kocwangco lwe-anodized, ngoku kusetyenziswa ngokubanzi kwi-aluminium kunye ne-aluminium alloys.
Iindidi ezahlukileyo zeendlela zokugcoba zijongwa ngokubanzi ngolu hlobo lwesisombululo se-electrolytic esetyenziswayo. I-Chromic acid (ebizwa ngohlobo lwe-I) yasetyenziselwa kwiindawo zokuqala zokungcebeleka kwezoshishino kuma-1920. Nangona kunjalo, namhlanje, izisombululo eziqhelekileyo ze-electrolytic zokwenza i-anodizing ziveliswa usebenzisa i-sulfuric acid (ebizwa ngohlobo lwe-II okanye uhlobo lwe-III ngokuxhomekeke kwinkqubo echanekileyo esetyenziswayo).
IiNzuzo eziSisiseko eziNinzi zoHlelo lwe-Anodizing
Izixhobo ze-aluminium e-Anodized zifumaneka kwiindawo zendiza kunye nezakhiwo, kunye neempahla zabathengi ezifana nezixhobo (iifriji, ii-microwaves, kunye ne-barbecues), iimpahla zezemidlalo (iibhola zebhola, iinqwelo zegolfu kunye nezixhobo zokuloba) kunye ne-electronics (iithelevishini, ii-smartphones kunye iikhomputha).
Izinzuzo ezisezantsi-zigciniweyo ziquka:
- Ingubo eqaqambileyo ilinganiswa neepende kunye neempuphu.
- Ngokugqithiseleyo, kunzima, ukuxhatshazwa kwexesha elide kunye nokuhlala ixesha elide. Ingubo ayifuni okanye i-chip. Ubunzima obuphezulu kunokuba upende kunye ne-powders.
- Ukulala ngonaphakade.
- Ukupheliswa komhlobo. Unokwenziwa lula kwakhona.
- Ayithengi xa kuthelekiswa nokupenda kunye neengubo zokugaya.
