Cov tawv nqaij tooj liab yog qhov muag muag, thiab cov xaim hluav taws xob uas yog cov khoom siv hluav taws xob zoo nkauj, thiab ua ib qho khoom siv liab-txiv kab ntxwv Cov Khoom Kho Vajtse thiab Npib, thiab Constantan siv hauv kev ntsuas tooj liab muaj zog ntawm 213 MpAs} Lub zog tooj liab muaj zog ntawm 213}} Lub ntsiab muaj zog ntxiv dag zog siv tau nyob rau hauv cu-based alloys .
Copper alloy yog alloys raws tooj liab, nyob rau hauv uas yog ib qho kev txhim kho atoms thiab cov kuab tshuaj oms los txiav txim siab txog qhov uas yav dhau los yaj nyob rau hauv intation . Cov no yog qhia raws li cov kev cai heeve-roty, tooj liab-zinc (npib tooj liab-zinc (npib tooj liab-zinc (npib tooj liab), coj tooj liab, thiab tshwj xeeb tooj liab, thiab tshwj xeeb alloys . Txuas ntxiv, tsawg tus tooj liab alloys tuaj yeem txhawb nqa los ntawm kev kho cua sov {}}; Yog li, kev ua haujlwm txias thiab / lossis tsim kev daws cov khoom siv los txhim kho cov khoom siv tshuab no.
Cov khoom ntawm tooj liab
Tooj liab yog qhov muag muag, ducast thiab malloable cov khoom siv rau raj tsim nyog ua rau tooj liab thiab nws cov alloys suav nrog:
Zoo heev thermal conductivity . tooj liab muaj cov khoom siv hluav taws xob ntau dua li txhuas cov hluav taws xob yog delocalized.
Cov hluav taws xob hluav taws xob zoo . qhov kev coj ua hluav taws xob yog 97%, tooj liab tau ntau dua, tus nqi qis dua, tooj liab tau muab piv txwv ntau dua muab qhov kub thiab txias, cov thermal thiab hluav taws xob kev coj ntawm cov hlau yog sib xws thaum txo qhov kev coj ua hluav taws xob nce ntxiv rau hauv wiedeman cov kev cai lij choj hauv Wiedeman cov cai lij choj.
Zoo corrosion . tooj liab tsis hnov nrog cov txheej txheem ntawm cov roj av uas muaj cov roj av, tab sis txhuas tooj liab, thiab txhuas ua yeeb yam zoo tshaj rau ntsev corrosion .
Zoo biofouling Kuj
Zoo machini. tshuab tooj liab yog ua tau, txawm hais tias alloys tau zoo dua rau kev tsim lub tshuab raj zoo .
Khaws cia ntawm cov neeg kho tshuab thiab hluav taws xob ntawm cov khoom siv hluav taws xob ntawm cryogenic kub
Diamism
Siv ntawm tooj liab thiab tooj liab alloys
Keeb kwm, alloying tooj liab nrog lwm cov hlau, yog thawj xyoos dhau los ntawm kev tshawb fawb tooj liab thiab suav nrog tin, arsenic, lossis lwm yam Cov hlau . Cov hlau loj loj yog cov khoom siv hluav taws xob (15%) {{{9} (Cu-zn) thiab bronzes (cu-sn) tau siv dav hlau, cov khoom siv suab paj nruag, thiab cov ntxaij vab tshaus, thiab Npib thiab Bronze-zoo li alloys thiab sib xyaw ua ke, tau siv rau npib dua ib lub sij hawm ntev dua rau cov khoom siv hluav taws xob ntev dua thiab niaj hnub no, thiab feem ntau yog siv rau cov khoom siv hluav taws xob me me thiab niaj hnub no tsos .
Electrolytic-tawv pitch (ETP) Tooj
Electroly tawv tawv tooj liab, tsis muaj tseeb c11000, nrog qhov siab tshaj plaws ntawm lub ntiaj teb) Ntshiab . nws muaj 0. Hlau .}} ntxhib ib nrab ntawm tag nrho cov tooj liab mined yog siv rau cov hlau hluav taws xob thiab cov cable. Ntshaw dawb tooj liab muaj cov hluav taws xob zoo tshaj plaws thiab thermal conductivity ntawm cov lag luam hlau. Qhov kev ua haujlwm ntawm tooj liab yog 97% ntawm nyiaj. Vim nws cov nqi qis dua thiab ntau dua ntau nplua nuj, tooj liab tau ib txwm yog cov qauv siv rau cov ntaub ntawv sib kis.
Tooj daj
Tooj dag yog cov lus dav dav rau ntau hom kev sib txawv, ua rau muaj cov khoom siv zinc nyob rau hauv cov khoom siv zinc nyob rau hauv cov khoom sib txawv nrog cov ntsiab lus tooj liab ntau dua 63% yog feem ntau Ciav ntawm tej copper alloy thiab yog puab los ntawm cov khoom txias uas tsis yooj yim rau cov xim daj lossis xim loj dua rau cov xim daj kom daj rau cov nyiaj nyob ntawm qhov zinc cov ntsiab lus . Qee cov kev siv rau tooj dag zog, cov khoom siv suab paj nruag, cov khoom siv suab paj nruag, cov hlua khau, cov hlua khau, cov hlua khi tau siv rau cov vov tsev thiab pob zeb ua kom pom kev vim lawv pom kev tsos .
Piv txwv li, tsis muaj C26000 cartridge tooj dag zog ua si (70/30) Pob khawm, cov mos txwv sib xyaw lossis cov kav dej kav dej khov kho .
Tooj
Lub bronzes yog tsev neeg ntawm tooj liab alloys ib txwm muaj feem ntau ntawm cov tooj liab thiab lwm yam khoom siv (}}} Feem ntau lawv tau siv thaum, ntxiv rau corrosion tsis kam, zoo tensile cov khoom yuav tsum muaj lub zog loj tshaj plaws, rau 1,400 mpa) ntawm ib qho tooj liab-based alloy {}}
Keeb kwm, alloying tooj liab nrog lwm cov hlau, yog thawj xyoos dhau los ntawm kev tshawb fawb tooj liab thiab suav nrog tin, arsenic, lossis lwm yam cov hlau . bronze, thiab sib xyaw ua ke, thiab cov pob khoom sib xyaw ua ke feem ntau siv rau cov vaj tsev vov tsev thiab facade cladding vim lawv pom pom .
