Aluminium lub npe rau corrosion tsis kam ua ntau zaus ua rau kev ua kom tsis to taub txog nws txoj kev ua tau zoo hauv kev ua haujlwm hauv qab dej ib puag ncig. Thaum cov ntaub ntawv txhuas ib txwm ua ib txheej oxide tiv thaiv oxide, ntsev ua kom nkag siab zoo. Tsab ntawv no yuav tshuaj xyuas li cas cov dej qab zib alloys thiab muab cov ncauj lus kom ntxaws.
Qhov txuj ci kev kawm qab ntsev qab ntsev
Salwwater ua nrawm nrawm corrosion los ntawm peb lub koom haum me me:
Chloride nres: Chloride ions hauv dej hiav txwv chim rau 5 {}}}}}}}}}}}}. 5mm \/ xyoo nyob ntawm cov xwm txheej.
Galvanic cov tshuaj tiv thaiv: Thaum 6061 phaj aluminium hu ua cov hlau uas muaj cov hlau uas muaj cov hlau tsis zoo li, Galvanic corrosion tuaj yeem tshwm sim ntawm tus nqi txog li 10x ib txwm.
Crevice corrosion: Cov tshuaj ntsev ua kom tsim cov oxygen
Alloy-tshwj xeeb tsis muaj zog
5083 alloy alloy: Lub marine-cov kev sib tw marine-cov ntsev ua kom tsis txhob muaj ntsev zoo dua li feem ntau, nrog cov neeg corrosion corrosion ntawm {2}}. 05mm \/ xyoo nyob rau hauv submerged tej yam kev mob. Lub 4.5% cov ntsiab lus magnesium hauv 5083 txhuas cov khoom tau txhim kho nws cov oxide txheej ruaj khov.
5052 cov khoom siv txhuas: Thaum zoo heev rau cov roj cua tshuab, txuas ntxiv ua cov dej qab zib txuas ntxiv ua rau corrode ntawm 0. {}}. 3mm \/ xyoo tsis muaj kev tiv thaiv. Nws 2.5% cov ntsiab lus magnesium muab cov kev tiv thaiv kev cuam tshuam.
6061 Txhuas Phaj: Tsawg kawg nkaus haum rau Savtry ntawm cov alloys, 6 {11 Alloy} 61 Alloy Alloy tuaj yeem qhia cov tub rog ua haujlwm vim nws cov ntsiab lus tooj liab.
Kev Tiv Thaiv Kab Lus Qhia
Cov Kev Xaiv Deg
Txoj kev: Hom III Hardcoat Anodizing Ntxiv {{}} μm tiv thaiv 6061 cov nqi sib xyaw ua ke los ntawm 90%.
Txheej: Three-coat epoxy-polyurethane systems on 5052 aluminum sheet provide 10,000+ hours salt spray resistance.
Kev Hloov Tshiab Kev Hloov Neeg: Chromate hloov dua roj rau 5083 Txhuas phaj txhim kho cov xim nplaum thiab ntxiv ib ntus corrosion tsis kam.
Kev txiav txim siab tsim

Cov Ntaub Ntawv Kev Ua Haujlwm Tiag Tiag
Cov ntaub ntawv teev tseg qhia:
Kev Tiv Thaiv Tsis Pub 6061 Txhuas Phaj Ua Tsis Tau Hauv 2-3} xyoo nyob rau hauv kev kub ntxhov marinas
Kom tswj tau 5083 aluminium alloy halls kav 25+ xyoo
Txheej 5052 Aluminium ntawv qauv muaj sia nyob rau muaj txoj sia nyob {1}} xyoo nyob rau hauv ntug hiav txwv ib puag ncig
Los ntawm kev nkag siab Saltwater cov teebmeem tshwj xeeb ntawm cov tswv yim sib txawv, cov khoom siv tiv thaiv uas tsim nyog tau ua tiav kev ua haujlwm ntawm marine.
