Vim li cas 5754 thiab 5083 alloys zoo tagnrho rau kev thauj cov marine?
Ob alloys Excel hauv cov av marine vim lawv cov ntsiab lus magnesium (5083: {}}. 6%}. 6%}. 6%}. 5083 Muaj lub zog siab dua (275 MPa tensile) rau hull cov qauv, thaum 5754 muab cov formability zoo dua rau cov roj tso tsheb hlau. Lawv cov zeb tiav saum npoo ib txwm ua ib txheej oxide tiv thaiv, txo cov kev xav tau txij nkawm. Cov alloys tseem muaj ntau weldable yam tsis muaj kev sib cuam tshuam corrosion tsis kam, tseem ceeb rau txua nkoj.
Yuav ua li cas zeb tiav sib txawv los ntawm polished tiav hauv kev thov thauj hauv cov ntawv thov?
Zeb tiav khaws cov nqaij nyoos, tsis muaj zog los ntawm dov, muab cov nyiaj txuag thiab kev tiv thaiv oxidation. Polished tiav (piv txwv li, rau 5083) txhim kho kev ua kom zoo nkauj thiab txo kev sib txhuam hauv cov chaw tsheb siab zoo li cov plag tsev. Mill tiav yog qhov nyiam rau cov txheej txheem qhov chaw nyob qhov twg nto nto nyob sab nraud, thaum lub sij hawm polished xaus. Ob qho kev xaiv tswj hwm cov khoom siv cov khoom siv me me tab sis sib txawv hauv kev ua haujlwm tom qab.
Yuav ua li cas vuam lug pom zoo rau 5754\/5083 coils hauv tsheb shocks?
MIG vuam nrog 5356 tus tub lim hlau yog txheem rau 5083 tiv thaiv tiv thaiv kev tawg los ntawm cov magnesium poob. Tig vuam yog qhov zoo dua rau nyias 5754 nplooj ntawv (piv txwv li, tso roj av) rau qhov tseeb. Preheating ({60-100 degree) minimizes thermal kev ntxhov siab hauv tuab 5083 ntu. Tom qab-Weld Annealing (250 degree) rov qab corrosion tsis kam nyob rau hauv tshav kub-cuam tshuam zones. Zam kev siv tshuaj pleev xim oxy-acetylene los tiv thaiv porosity.
Muaj 5754 hloov 5083 hauv kev thauj khoom chassis?
Tsis muaj {-5083 '}' mpa vs. 5754's 215 MPa) yog qhov tseem ceeb rau chassis raws li kev thauj khoom. 5754 cov khoom sib dhos sib luag zoo li cov khoom siv sab hauv lossis cov khoom tsis muaj zog. 5083 Qaug zog tsis kam (10 ^ 7 mus txog ntawm 100 MPA) Outperforms 5754 hauv kev siv ntev ntev. Nqi tau txais txiaj ntsig, 5754 yog pheej yig dua tab sis kev cuam tshuam cov nyiaj muaj peev xwm.
Qhov kub nyhav li cas 5083 kev ua yeeb yam hauv cov thawv ntim tsheb?
5083 Saib xyuas lub zog rau -196 degree, zoo tagnrho rau cryogenic thauj. Saum toj no 65 degree, nws lub zog poob los ntawm 20%, xav tau tsim qauv. Thermal nthuav (23.8 μ k) sib phim hlau, txo qis kev ntxhov siab hauv ntau cov ntaub ntawv sib dhos. Hluav taws kub tsis kam (melting point 570 degree) steppasses carbon hlau, txhim kho kev nyab xeeb.
