I-7075 AlUminium Allouy, njenge-Aluminium ye-Aluminium ene-chincring ye-zinc, isetyenziswa ngokubanzi kwi-aerospace, i-aerospace, imizi-mveliso yasemkhosini nasekugcinweni ngenxa yeempawu zayo ezihle kakhulu kunye neempawu zendlela. Nangona kunjalo, kukho imiceli mngeni xa usenza unyango olungaphantsi, ngakumbi xa usenza ithamsanqa ukuphucula ukumelana nokunganyangeki kunye nobunzima obuphezulu.
Ithayitha yinkqubo ye-electrochemical inkqubo yefilimu yealuminium oxide enokusekwa kumphezulu wentsimbi ukuze iphucule ukunyangwa kwentsimbi, ukunganyangeki kwengqondo kunye nokubulala i-aesthetics. Nangona kunjalo, ngenxa yomxholo we-chinci ophakamileyo kwi-7075 alloy kunye neempawu ze-al-ZN-ZN-ZN-MG, ezinye iingxaki zithambekele ukuba zenzeke ngexesha lokuthambisa:
1. Umbala ongalinganiyo:Inqaku le-zinic linempembelelo enkulu kwifuthe le-oxidation, elinokukhokelela ngokulula kwimiphetho emhlophe, amabala amnyama, kunye nemibala engalinganiyo kwi-oxidation. Ezi ngxaki zibonakala ngakumbi xa izama ukuyinyanzela kwimibala eqaqambileyo (enjengebomvu, iorenji, njl njl) ngenxa yokuba uzinzo lwale nto ihlwempuzekile.
I-2. AYanzo oneleyo kwifilimu ye-oxide:Xa inkqubo yendabuko ye-Alfuric Alvid isetyenziselwa ukuphatha izabelo ze-Aluminium ezi-7, ngenxa yokusasazwa okungalinganiyo kunye nokwahlulahlula amacandelo e-aluminium, ubungakanani beebrowni zevidiyo ziya kwahluka kakhulu emva kokuthambisa. Oku kukhokelela kulwahluko kumgangatho kunye nokunamathela kwifilimu ye-oxide kwiindawo ezahlukeneyo, kwaye ifilimu yeside kwezinye iindawo inobuthathaka.
Ukulungiselela ezo ngxaki, kubalulekile ukuba bamkele inkqubo ekhethekileyo yokutosa okanye yokuphucula inkqubo esele ikho, njengokulungelelanisa ubume, ubushushu kunye nokuxinana kwangoku, okuya kuchaphazela ifilimu ye-ofisi ye-oxide. Umzekelo, i-PH ye-electrolyte iya kuchaphazela inqanaba lokukhula kunye ne-pore ye-pore yefilimu yeside; Ukuxinana okwangoku kunxulumene ngokuthe ngqo nobunzima befilimu ye-oxide. Ngokulawula ngokuchanekileyo le parameters, ifilimu engabekwa i-Aluminium engabekwanga iimfuno ezithile inokwenziwa ngokwezifiso.
Iimvavanyo zibonisa ukuba emva kokuthambisa i-Aluminium ye-Aluminium ye-Aluminium, ifilimu yeside enobunzima be-30um-50um inokufunyanwa. Le filimu yesidida ayinakukwazi ukhuseleko ngokukhuselekileyo i-Aluminium Alwal Alfrest kwaye yandise ubomi benkonzo, kodwa ifezekisa iimfuno zentsebenzo ngokuhlengahlengisa iiparameters zenkqubo. Umphezulu we-Aluminium Alloty emva kokutolifa unokukhwela ukufunxa imibala ye-organic okanye i-Inorganic inike imibala ye-aluminium ye-Aluminium enesityebi ukuze ihlangane neemfuno zobuhle.
Kufuphi, Ithayitha yindlela esebenzayo yokuphucula ukusebenza kwe-Aluminium ye-Aluminium ye-7. Ngokuhlengahlengisa iiparameters zenkqubo, ifilimu yokukhusela edibana nobunzima obuthile kunye neemfuno zobunzima zinokulungiswa, ezisandisa kakhulu icandelo lesicelo se-alloys.
