Aluminium alloystau txais lawv qhov chaw ua ib qho ntawm cov khoom siv ntau yam hauv kev lag luam niaj hnub no. Los ntawm aerospace mus rau kev tsim kho, lawv qhov hnyav thiab ruaj khov ua rau lawv tseem ceeb. Txawm li cas los xij, ib qho ntawm lawv cov khoom tseem ceeb tshaj plaws yog lawvcorrosion kuj. Tab sis dab tsi muab cov alloys lawv muaj peev xwm tiv taus ib puag ncig hnyav? Cia peb tshawb nrhiav kev tshawb fawb thiab kev siv tom qab qhov kev tiv thaiv corrosion ntawm aluminium alloys thiab cov cuab yeej no tau txais txiaj ntsig zoo li cas hauv kev lag luam thoob ntiaj teb.
Nkag siab txog Corrosion: Ib qho Kev Sib Tw rau Cov Hlau
Corrosion tshwm sim thaum hlau hnov mob nrog ib puag ncig yam xws li oxygen, noo noo, lossis tshuaj lom neeg, ua rau degradation. Rau feem ntau cov hlau, cov txheej txheem no ua rau cov khoom tsis muaj zog thaum lub sij hawm, cuam tshuam nws cov kev ua tau zoo thiab kev ua haujlwm ntev. Aluminium alloys, txawm li cas los xij, sawv sib nrug vim lawv lub peev xwm los tiv thaiv corrosion.
Tsis zoo li hlau, uas ua rau xeb thaum oxidized, aluminium tsim ib txheej tiv thaiv ntawm txhuas oxide. Cov yeeb yaj kiab no nyias, pom tsis tau ua ib qho thaiv, tiv thaiv cov hlau hauv qab los ntawm kev raug ntxiv.
Kev Tshawb Fawb Tom Qab Corrosion Resistance hauv Aluminium Alloys
Cov lus zais rau aluminium alloys 'corrosion tsis kam yog nyob rau hauv lawv cov tshuaj lom neeg thiab cov alloy muaj pes tsawg leeg:
1.Aluminium Oxide Txheej Txheej
Thaum raug huab cua, txhuas reacts nrog oxygen los tsim txhuas oxide (Al2O3). Cov txheej no yog qhov tshwj xeeb tawv, kho tus kheej, thiab tsis-reactive. Txawm tias khawb los yog puas lawm, cov oxide txheej regenerates sai sai, tswj cov hlau tiv thaiv.
2.Alloying Elements thiab lawv lub luag haujlwm
Ntxiv cov ntsiab lus xws li magnesium, silicon, lossis zinc ntxiv txhim kho aluminium qhov kev tiv thaiv corrosion los ntawm kev hloov kho nws cov qauv thiab kev ua haujlwm. Piv txwv li:
•Magnesium-nplua nuj alloys: Zoo tagnrho rau thaj chaw marine vim lawv zoo heev tiv thaiv dej ntsev corrosion.
•Silicon-raws li alloys: Feem ntau siv rau hauv tsheb qhov chaw rau kev txhim kho hnav tsis kam.
3.Txheej txheem Passivation
Ntau cov aluminium alloys dhau mus dhau kev ua haujlwm, tshuaj kho mob uas ntxiv dag zog rau cov txheej txheem oxide, kom ntseeg tau tias muaj kev tiv thaiv mus ntev hauv cov cheeb tsam hnyav xws li acidic lossis alkaline.
Daim ntawv thov lub neej tiag tiag uas nthuav tawm Corrosion Resistance
Aluminium alloys yog cov pob txha ntawm ntau qhov kev lag luam, ua tsaug rau lawv cov kev tiv thaiv corrosion. Nov yog qee qhov piv txwv:
•Aerospace Kev Lag Luam: Cov khoom siv dav hlau tau raug rau qhov siab tshaj plaws thiab huab cua. Aluminium alloys muab cov kav ntev thiab ua haujlwm rau cov dej noo, ua rau lawv zoo tagnrho rau lub fuselage thiab tis qauv.
•Kev tsim kho: Lub qhov rais thav duab, vov tsev, thiab cladding ua los ntawm txhuas alloys tuaj yeem tiv taus ntau xyoo los nag thiab tshav ntuj yam tsis muaj kev puas tsuaj loj.
•Kev siv Marine: Tej nkoj nquam, nkoj, thiab offshore platforms cia siab rau aluminium alloys los tiv thaiv cov corrosive los ntawm dej ntsev, ncua lawv lub neej ua haujlwm.
•Electronics: Corrosion-resistant aluminium alloys tiv thaiv cov khoom los ntawm ib puag ncig kev puas tsuaj, ua kom muaj kev ntseeg siab hauv cov khoom siv xws li smartphones thiab laptops.
Case Study: Aluminium Alloys hauv Marine Engineering
Xav txog kev siv aluminium-magnesium alloys hauv nkoj tsim. Cov nkoj steel niaj hnub yog qhov yooj yim rau xeb, xav tau kev saib xyuas ntau thiab tiv thaiv txheej. Aluminium-magnesium alloys, txawm li cas los xij, tiv thaiv corrosion ib txwm, txo cov nqi kho thiab txuas ntxiv lub neej ntawm cov nkoj hauv hiav txwv.
Ib qho piv txwv tseem ceeb yog kev tsim kho cov nkoj loj. Kev tiv thaiv corrosion ntawm aluminium tsis tsuas yog txhim khu kev ruaj ntseg tab sis kuj txo qhov hnyav, txhim kho roj efficiency - yeej-yeej rau cov tswv lag luam thiab ib puag ncig.
Vim li cas Corrosion Resistance Matters rau Sustainability
Lub neej ntev thiab kev saib xyuas qis ntawm aluminium alloys pab txhawb kev ruaj khov. Lawv txo qhov kev xav tau ntawm kev hloov pauv thiab kho tsis tu ncua, txuag cov peev txheej thiab txo cov khoom pov tseg. Tsis tas li ntawd, txhuas yog cov khoom siv rov ua dua tshiab, khaws nws cov khoom tiv thaiv corrosion txawm tias tom qab rov ua dua tshiab.
Kev lag luam nrhiav kev daws teeb meem zoo ib puag ncig yog nce mus rau aluminium alloys rau lawv lub peev xwm los ua ke kev ua tau zoo nrog kev ruaj khov.
