Marine aluminium ntawv yog ib qho kev loj hlob sai - ntu hauv kev lag luam hlau. Shipbuilders thiab offshore engineers xav tau cov ntaub ntawv uas yog lub teeb yuag, tiv thaiv xeb, thiab muab lub zog siab hauv cov dej hiav txwv hnyav. Kev tsim cov qib siab - zoo marine- qib aluminium ntawv yuav tsum muaj kev tswj xyuas nruj, thiab tus neeg muag khoom muaj peev xwm ua tau raws li cov qauv no qhia lawv lub zog tiag tiag hauv kev lag luam thoob ntiaj teb.
Peb yog GNEE, Tuam Tshoj marine aluminium ntawv xa khoom. Peb tshwj xeeb hauv kev tsim cov marine- qib aluminium alloys. Peb muab kev ruaj khov, ntawv pov thawj txhuas daim hlau uas ua tau raws li cov qauv kev tsim khoom thoob ntiaj teb. Txawm hais tias koj tab tom tsim cov nkoj me me, cov neeg caij nkoj ferries, lossis cov chaw nres nkoj loj, xaiv cov khoom siv txhuas zoo yog thawj kauj ruam rau kev ua tiav.
Vim li cas lub nkoj tsim kev lag luam siv 5000 series txhuas daim hlau?
Marine ib puag ncig rhuav tshem cov qauv hlau. Rau lub nkoj kom muaj sia nyob tau ntau xyoo hauv dej hiav txwv, nws yuav tsum muaj cov hlau nplaum uas tsim kom muaj qhov ntom ntom, tus kheej - kho oxide txheej. Lub 5000-series txhuas siv Magnesium (Mg) ua nws thawj alloying keeb. Thaum cov ntsiab lus magnesium nyob nruab nrab ntawm 3.0% thiab 4.9%, cov hlau ua tiav qhov zoo tshaj plaws ntawm kev sib npaug ntawm lub zog tensile, zoo weldability, thiab tag nrho kev tiv thaiv rau seawater corrosion.
Alloys nrog magnesium siab dua (xws li 5083) muab lub zog siab tshaj plaws rau kev thauj khoom -cov kabmob hulls. Alloys nrog qis magnesium (xws li 5754) muab kev kho kom zoo dua qub rau cov qauv hauv tsev.

5083-H116 khaws ze li 90% ntawm nws lub zog tensile nyob rau hauv tshav kub-cuam tshuam cheeb tsam (HAZ) tom qab vuam. Qhov no yog qhov laj thawj tseem ceeb uas nws tau teev tseg rau qhov tseem ceeb ntawm lub hauv qab thiab cov bulkheads.
Qhov txawv ntawm ob lub xeev, H116 thiab H321 yog dab tsi?
Ntau tus neeg yuav khoom nug txog qhov sib txawv ntawm H116 thiab H321. Nyob rau hauv cov nqe lus ntawm yield thiab tensile zog, lawv yog ze li ntawm zoo tib yam. Qhov sib txawv yog nyob rau hauv kev ua metallurgical thiab yuav ua li cas lawv tuav cov kev tawm tsam tshwj xeeb.
- H116 (Huaj tawv tawv):Qhov kev npau taws no tshwj xeeb yog tsim los tswj cov nag lossis daus ntawm magnesium raws cov ciam teb. Los ntawm kev ua tib zoo tswj cov dov txo thiab cov nqi txias, H116 tiv thaiv magnesium los ntawm clumping. Qhov no ua rau H116 tiv taus heevexfoliation corrosion kuj(qhov twg cov hlau flakes tawm hauv txheej). Nws yog tus qauv kiag li rau sab nrauv hulls tas li submerged hauv dej hiav txwv.
- H321 (Strain Hardened thiab Stabilized):Qhov npau taws no dhau los ua qhov qis -kub cua sov tom qab dov. Qhov no stabilization xauv lub grain qauv nyob rau hauv qhov chaw. H321 yog heev resistant rauKev ntxhov siab corrosion cracking (SCC). Nws yog feem ntau nyiam rau cov khoom siv uas ua rau lub zog tsis tu ncua thiab kev vibrations, xws li lub txaj cav thiab lawj mounts.
Txhawm rau lav cov khoom no, GNEE sim ob qho tib si tempers raws liASTM G66 (ASSET Test)rau exfoliation kuj thiabASTM G67 (NAMLT)rau intergranular corrosion.
