Kuya kude kube nini i-aluminiyam i-oxidize kwaye idle emva kokusetyenziswa?
Icandelo eliphambili le-aluminium yi-aluminium kunye nenani elincinci lamacandelo e-alloy. Abanye abantu bacinga ukuba i-aluminiyam ayilulanga ukuba i-oxidize kuba kukho utshintsho oluncinci kumbala. Enyanisweni, i-aluminiyam yintsimbi esebenzayo kakhulu, kulula ukuyi-oxidize kunentsimbi. Isizathu sokuba ingabonakali kukuba i-aluminium oxide eyenziwe emva kwe-oxidation ayinambala kwaye ibonakala. Kwaye le filimu ye-oxide ihlukanisa i-aluminium yangaphakathi kunye noqhagamshelwano lomoya, ngoko ayiyi kuqhubeka i-oxidize, kwaye ngaloo ndlela ikhusela i-aluminium substrate. Ke i-aluminiyam yomelele nangaphandle konyango lomphezulu.
Kodwa ifilimu ye-oxide ayinakuchaphazeleka, i-aluminium oxide iyasebenza kwi-asidi kunye ne-alkali, kwindawo enomoya ongcolileyo, ifilimu ye-oxide itshabalaliswa lula, okubangelwa ukubola kwe-aluminium substrate, umonakalo. Ukuba isetyenziswe ngaphandle, ukukhanya kwelanga, kunye namanzi emvula aneasidi kuya kukhawulezisa ukubola kwealuminiyam. Ke ixesha elingakanani iprofayili yealuminiyam iya kuthi i-oxidize kwaye igxumeke xa isetyenzisiwe ikwaxhomekeke kwimekobume kunye nonyango lomphezulu wayo. Unyango olungaphezulu lweeprofayili ze-aluminium lubandakanya i-anodic oxidation, i-electrophoresis, ukutshiza, i-electroplating, njl njl. I-Anodic oxidation yindlela ye-electrochemical eyenza ifilimu ye-oxide eyenziweyo kumphezulu weeprofayili ze-aluminium, enzima kakhulu kunefilimu ye-oxide eyenziwe ngokwemvelo kwaye i ukuxhathisa kwi-corrosion nakwindawo enzima yangaphandle, kwaye ubomi benkonzo yolondolozo bunokufikelela kwiminyaka engama-25.
