Cov nqi corrosion ntawm aluminium 5 0 52 nyob rau hauv seasterater yog feem ntau,}. 03-0.07 mm \/ xyoo nyob rau hauv ib txwm ua tub rog. Tus nqi no tau txiav txim siab los ntawm kev ntsuas cov qauv (piv txwv li, ASTM G31 lossis G67) qhov chaw kuaj pom muaj rau dej hiav txwv lossis dej hiav txwv. Tej yam xws li dej kub, salinity, cov pa oxygen, thiab cov haujlwm microbial cuam tshuam. Piv txwv li, kev kub ntxhov (25-30 degree) tej zaum yuav nce me ntsis corrosion piv rau cov cheeb tsam colder. Kev tshawb nrhiav lub sijhawm ntev qhia tias txhuas cov txheej tiv thaiv oxide ntxiv, ua rau nws haum rau kev siv lub nkoj marine li nkoj lossis lawj fittings lossis lawj fittings lossis lawj fittings lossis lawj fittings lossis lawj fittings lossis lawj fittings.
Aluminium 5052 muaj zoo corrosion tsis kam tab sis tsis tshua muaj zog nyob rau hauv cov dej hiav txwv hnyav piv rau alloys zoo li} h116, uas yog qhov zoo tshaj plaws rau cov tub rog ib puag ncig. Thaum 5052 reseds pitting thiab corrosion vim tias nws magnesium (5083 Alloy 6061, txawm hais tias muaj zog, yog ntau dua qub rau corrosion hauv chloride-nplua nuj seodedater tshwj tsis yog anodized lossis coodized lossis coated. 5052 tawm tsam qhov sib npaug ntawm tus nqi, Weldability, thiab durability, ua rau nws zoo tagnrho rau kev tso tsheb hlau loj dua xws li cov panels roj lossis sab hauv.
Aluminium 5052 hauv Seasater feem ntau ntsej muag pitting corrosion thiab galvanic corrosion. Pitture tshwm sim thaum chloride ions nkag rau oxide txheej, tsim cov pitscevicized. Galvanic Corrosion tshwm sim thaum 5052 tiv tauj ntau cov hlau nplaum (piv txwv li, hlau lossis tooj liab) hauv dej hiav txwv. Cov tswv yim txhais tau xws li:
Siv cov ntaub ntawv insulating (piv txwv li, roj carkeets) los tiv thaiv cov hlau ncaj qha-rau-hlau sib cuag.
Ua ntawv thov cov txheej txheem tiv thaiv zoo li epoxy pleev xim lossis anodization.
Ua kom muaj kev tiv thaiv Cathodic zoo nrog kev tiv thaiv kab mob txi (piv txwv li, zinc).
Aluminium 5052 tau siv dav hauv cov tub rog ua haujlwm me me, xws li:
Nkoj hulls thiab decks: nws lub teeb yuag thiab weldability nplua meft me marft, tab sis feem ntau ua khub rau lub neej ntev.
Roj tso tsheb hlau luam: resards corrosion los ntawm qab ntsev txaws thiab diesel raug vim nws impermability.
Cov tshuab hluav taws kub: ua tau zoo nyob rau hauv cov nroj tsuag desalination nrog tswj seaswater flow thiab kub.
Cov khoom siv HVAC: siv hauv cov ducts thiab vaj tse uas nyob nraum qhov chaw coj mus ua dej hiav txwv tsis txaus ntseeg. Cov ntaub ntawv tshawb pom qhia tias muaj kev txij nkawm tsim nyog, 5052 tau ntev li 10-15 xyoo nyob rau hauv hiav txwv, tab sis tseem ceeb heev hauv hiav txwv, txawm hais tias tseem ceeb ntawm dej hiav txwv yuav xav tau kev txhim kho mus rau 5083 lossis 5086 alloys.
