Submarines siv aluminium alloys?
Marine-qib 5xx alloys ua rau cov ntsev ua kom qab ntsev nyob hauv Submine Hulls. Aluminium lub teeb pom kev tso cai rau kev tswj cov buoyancy thiab maneuverability. Acoustic Damping Panels Txo cov suab nrov los ntawm Sonar Nrhiav kom tau. Siab-resist lub bulkheads siv txhuas composites. Kev Txij Nkawm Muaj xws li kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv Galvanic corrosion.
Vim li cas cov txiv ntoo siv hauv dav hlau cua sov thermal?
Aluminium lub siab thermal conductivity tswj qhov kub thiab txias hauv lub tshuab nqus tsev. Multure Txheej Rwb thaiv tsev (mli) cov pam vov sib xyaw ua ke txhuas ntawv ci thiab cov yeeb yaj kiab polymer. Thaum tshav kub kav nrog Aluminium Wicks diss dissipate zog los ntawm cov khoom siv hluav taws xob. Refleative Txhuas Txheej Txheej Taug Kev Ua Ntej Disclecting Hnub Ci Hluav Taws Xob. Alloys zoo li 2219 muaj txoj sia muaj kev rov nkag cua sov kom sov txog 175 degree.
Aluminium withstand arctic?
Aluminium khaws cov ductility ntawm qhov kub uas muaj tsawg li -80 degree, tsis zoo li nyiav hlau. Alloy 5083 tau siv nyob rau hauv lub nkoj Iaterbreaker thiab Polar Tshawb Fawb Kev Tshawb Fawb. Anodized thaj chaw tiv thaiv kom cov khoom nplaum te ntawm cov cuab yeej. Thermal so hauv txhuas cov av tiv thaiv cov hws hauv huab cua txias. Cov khoom lag luam qis qis (cov chaw taws teeb.
Aluminium ua ua hauv cov chaw siab hluav taws xob siab?
Aluminium tsawg dua atomic tus xov tooj me me ua kom muaj kev ua kom zoo nyob rau hauv cov tshuaj tua hluav taws xob nuclear. Kev thaiv cov ntoo panels siv boron-aluminium composites kom nqus hluav taws xob. Satellite Cheebtsam cia siab rau txhuas rau txoj kev tiv thaiv kab ntsig txog cosmic. Tom qab-irradiation, Aluminium pov tseg yog yooj yim dua los lis ntau dua li cov hlau. Kev tshawb fawb txuas ntxiv ntawm Fusion Reactor daim ntaub ntawv.
Aluminium li cas Txhuas ntsej muag nyob rau hauv lub roob hluav taws ib puag ncig?
Sulfur-nplua nuj roj nrawm nrawm corrosion tshwj tsis yog tiv thaiv cov txheej txheem tiv thaiv. Cov cuab yeej ntsuas cov qauv siv refractory alloys allots los tawm tsam melting. Thermal tshuaj tsuag txheej txheem (piv txwv li, alumina) txhim kho durability nyob ze vents. Cov chaw soj ntsuam saib xyuas txhuas cov qauv coj ua rau kev xa tawm sai. Kev tawg npe-tawg, txhuas cov khib nyiab yog yooj yim dua rau kev rov qab ua dua li lwm cov hlau.
