Resistant rau dej hiav txwv corrosion: Magnesium cov ntaub ntawv ntom nti oxide, thiab tuaj yeem tiv thaiv nruj hauv qab ntsev (5% sodium vloride tov, 35 degree).
Lub teeb yuag: Cov ceev no tsuas yog 2.72g / cm³, uas yog 60% sib dua dua li cov hlau, ua kom haum cov roj ua haujlwm ntawm cov nkoj.
Nruab nrab lub zog thiab lub zog nruj me ntsis: tensile zog {}} mpa}}}}}, lub lawj, almour bulkhead, thiab lwm yam.
Cov Khoom Siv Neeg Kho Tshuab
Cov neeg kho tshuab kev ua haujlwm ntawm 5052 marine qib txhuas yuav tau siv rau hauv tus account ob qho tib si rigidity thiab tawv:
Lub zog tensile: 170MPA hauv Annealed State (O), 230MPA hauv lub sijhawm txias (H34), ntsib lub zog uas yuav tsum muaj lub zog ntawm Hull txheej txheem.
Qoob qaug zog: Zoo dua 6061 alloy alloy, haum rau cov chaw nkoj uas nquag yuav tsum yoj cuam tshuam.
Formancion: 5052-} o-aluminium daim ntawv tuaj yeem ua los ntawm kev sib sib zog nqus, khoov,} h32 / h34 tswj cov qauv ruaj khov.
Corrosion Kuj
Lub corrosion tsis kam ntawm 5052 los ntawm nws cov alloy muaj pes tsawg leeg thiab microstructure:
Hla zaj duab xis tiv thaiv: Cov ntsiab lus magnesium siab, al₂o₃-mo modoo composite oxide kev ua yeeb yaj kiab lawm yog qhov zoo dua 3003, 6061 thiab lwm yam alloys.
Lub luag haujlwm ntawm chromium: inhibits intergranular corrosion, thiab tswj hwm kom ntxhov siab corrosion tawg (SCC) tom qab vuam.
Kev sib piv ua piv txwv: Hauv cov tshuaj ntsev kuaj, tus qauv ntawm lub cev ntawm 5}}}}}}}}}}. {}}. {}}
Cov tswv yim thov:
Anodizing lossis anti-corrosion txheej yog pom zoo rau cov ntu ntev (xws li Hull daim hlau).
Cov gaskets yuav tsum tau siv thaum nws muaj kev sib cuag nrog hlau los tiv thaiv cov corrosion corrosion.
Vuam Khoom
5052 txhuas vuam ua tau zoo, tab sis cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
Vuam txoj kev
Tig Vuam: Pom zoo rau nyias daim hlau (tsawg dua lossis sib npaug nrog 6mm), tam sim no} A, Argon Roj Flow {} l} l u / min. Thaj tsam vuam yog weld zoo nkauj thiab me me.
MIG VUAM: Haum rau nruab nrab thiab tuab dua lossis sib npaug lossis sib npaug ntawm 6mm), tam sim no}} {% nws) kom nce nkag.
Laser Vuam: High efficiency thiab deformation me me. Nws yuav tsum tau tswj hwm lub zog ({2-4 kw) thiab vuam ceev ({1}} m / min).
Vuam hlau xaiv
ER5356 (MG 5%): Versatility ntau zog, Weld lub zog kaw ze rau cov khoom siv, zoo heev corrosion.
ER5183 (MG 4.5%): Haum rau cov ntu kev ntxhov siab, Weld tensile muaj peev xwm ncav cuag 250mpa.
Tom Ntej-Welding Kho
Tus weld yuav tsum tau pickled (10% hnoos {1}}}}}}}% los tshem tawm cov accide olomal 18v) kom rov ua kom haum corrosion.
Zam kev pleev xim ncaj qha rau ntawm thaj chaw weld, nws raug nquahu kom siv cov thwj tim hloov dua tshiab ua ntej.
