7075 aluminium alfoy, oo ah 7 taxane ah aluminium aluminium alumit oo leh zinc-ka sare, waxaa si weyn loogu isticmaalaa areospace, militariga iyo soo-saareyaasha soosaarka sare iyo astaamaha safka sare sababtuna tahay astaamaha farsamada ee wanaagsan iyo astaamaha fudud. Si kastaba ha noqotee, waxaa jira caqabado qaarkood marka la fulinayo dawada dusha sare, gaar ahaan marka uu ku gudajiro caajisiinta si kor loogu qaado iska caabbigiisa isku-darka iyo adkeynta dusha sare.
Caano-goynta waa geedi socod koronto oo ku saabsan filimka aluminium oksinium lagu sameyn karo dusha sare ee birta si loo wanaajiyo cabashadiisa caabbinta, iska caabbinta dhiigga iyo suuxinta. Si kastaba ha noqotee, sababtuna tahay zinc-ka ugu sarreeya ee ah 7075 aluminium alfoy iyo astaamaha isku-darka al-zn-mg aloy, dhibaatooyinka qaar ayaa u nugul inay dhacaan inta lagu jiro anaga
1. Midab aan sinnayn:Qeybta Zinc waxay saameyn weyn ku leedahay saameynta oksidation, kaas oo si fudud u horseedi kara geesaha cad, dhibco madow, iyo midabbo aan sinnayn oo lagu xidho ka dib oksidation. Dhibaatooyinkaas ayaa si gaar ah u muuqda markii ay isku dayaan inay u galaan midabyo dhalaalaya (sida casaan, oranji, iwm.) Sababta oo ah xasilloonida midabadaasi waa mid liidata.
2. Abuur ku filan oo ku filan filimka okside:Markii geedi socodka dhaqanka ee xargaha xaraashka ah ee xaraashka ah loo isticmaalo in lagu daweeyo 7 taxanaha aluminium aluminium allum, sababtuna tahay aluminium alfoy-ka aluminium, oo ah cabirka micropores dusha sare ee filimka dusha sare ee filimka si weyn ayaa loo kala saarayaa. Tani waxay keenaysaa kala duwanaanshaha tayada iyo dhajinta filimka okside ee filinka kala duwan ee goobaha kala duwan, iyo filimka okside ee goobaha qaarkood ay leeyihiin daciifnimo oo xitaa dhici kara.
Si loo xaliyo dhibaatooyinkaas, waxaa lagama maarmaan ah in la qaato geedi socod gaar ah oo loo yaqaan 'anoodation' ama la wanaajiyo nidaamka jira, sida hagaajinta halaaqa, heerkulka iyo cufnaanta hadda ka mid ah elektrolyte, oo saameyn ku yeelan doonta tayada iyo waxqabadka filimka okside. Tusaale ahaan, PH ee elektaroonigga ah ayaa saameyn ku yeelan doonta heerka konta iyo qaab dhismeedka filimka oker ah; Cufnaanta hadda jirta waxay si toos ah ula xiriirtaa dhumucda iyo adkaanta filimka okside ah. Adigoo si sax ah u xakameynaya cabbirradan, filim aluminium aluminium ah oo buuxiya baahiyo gaar ah ayaa loo habeyn karaa.
Tijaabooyinku waxay muujinayaan in ka dib markii ay aluminium taxane ah aluminium alfoy, oo ah filim okside leh oo dhumuc weyn leh 30um-50um waa la heli karaa. Filimkan okside-ka ah kaliya kama difaaci karo aluminiumka alfoy alumbrate oo ku dheereeya noloshiisa adeegga, laakiin wuxuu sidoo kale la kulmayaa shuruudaha waxqabadka gaarka ah isagoo la qabsanayo cabbirrada nidaamka. Dusha sare ee aluminium aluminiz ka dib markii ay aluminising-ka sidoo kale lagu carqaladeyn karo si ay u nuugaan midabka dabiiciga ah ama tortaginic si loo siiyo aluminium aluminium olators-ka si ay ula kulmaan shuruudaha qurxinta ee kaladuwan.
Marka la gaaro, Caano-goynta waa hab wax ku ool ah oo lagu wanaajiyo waxqabadka 7 taxanaha aluminium aluminium allus. Adigoo hagaajinaya cabirka hanaanka, filim ilaalin ah oo buuxisa shuruudaha adag iyo dhumucda qaro weyn ayaa la diyaarin karaa, kuwaas oo si weyn u ballaarinaya goobta arjiga ee aluminium ally.
