Copper (Cu) thiab tooj liab-nickel (copper-nickel (Cu-Ni)) alloys yog ob qho tib si cov ntaub ntawv tseem ceeb, tab sis lawv cov kev sib xyaw thiab cov khoom sib txawv ua rau lawv haum rau cov kev siv sib txawv, kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb ntawm kev xaiv cov khoom siv rau koj qhov project - thiab thaum nws los txog rau qhov xav tau ib puag ncig, peb cov khoom Cu-Ni sawv ua qhov kev xaiv zoo tshaj.
Ntawm nws cov tub ntxhais, tooj liab ntshiab yog ib qho muag muag, cov hlau uas paub zoo rau hluav taws xob thiab thermal conductivity. Nws yog cov ductile heev, ua kom yooj yim rau hauv cov xaim, cov kav dej, thiab cov ntawv txheeb, uas piav qhia nws txoj kev siv dav hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Txawm li cas los xij, cov tooj liab ntshiab muaj cov kev txwv tseem ceeb: nws yog qhov yooj yim rau corrosion nyob rau hauv ib puag ncig hnyav, tshwj xeeb tshaj yog thaum raug dej ntsev, acids, los yog muaj kuab paug. Thaum lub sij hawm, nws tsim ib qho ntsuab patina (oxidation txheej), uas tuaj yeem ua rau cov khoom tsis muaj zog thiab cuam tshuam kev ua haujlwm hauv cov ntawv thov xws li marine lossis tshuaj ua haujlwm.
Cu-Ni alloys, los ntawm qhov sib txawv, muab cov tooj liab nrog npib tsib xee (feem ntau 10-30% npib tsib xee, ntxiv rau me me ntawm cov hlau thiab manganese) los daws cov kev qaug zog no. Qhov kev sib xyaw no hloov pauv cov khoom siv, pib nrogsuperior corrosion kuj. Cov ntsiab lus npib tsib xee tsim cov txheej tiv thaiv oxide uas tiv thaiv pitting, crevice corrosion, thiab yaig - txawm nyob rau hauv cov dej ntsev, dej brackish, los yog cov khoom siv hluav taws xob. Qhov no ua rau Cu-Ni zoo tagnrho rau marine Cheebtsam xws li nkoj hulls, seawater intake systems, thiab offshore roj rig piping, qhov twg ntshiab tooj liab yuav sai sai degrade.
Mechanical zog yog lwm qhov chaw uas Cu-Ni outperforms ntshiab tooj liab. Thaum cov tooj liab ntshiab yog ductile, nws tsis muaj lub zog tensile xav tau rau kev siv siab. Cu-Ni alloys, ua tsaug rau lawv cov ntsiab lus alloying, muaj zog dua thiab hardness, ua rau lawv haum rau cov khoom hnyav xws li twj tso kua mis, li qub, thiab cov raj cua sov. Lawv kuj khaws tau yooj yooj yim, tso cai rau kev yooj yim fabrication yam tsis muaj kev xyiv fab durability.
Nyob rau hauv cov nqe lus ntawm thermal thiab hluav taws xob conductivity, ntshiab tooj liab tseem ua, tab sis Cu-Ni tswj kom txaus conductivity rau feem ntau cov kev xav tau kev lag luam - thaum ntxiv cov txiaj ntsig tseem ceeb ntawm kev tiv thaiv corrosion. Qhov kev sib npaug no ua rau Cu-Ni cov khoom ntawm kev xaiv nyob rau hauv ib puag ncig uas ob qho tib si kev ua tau zoo thiab lub neej ntev teeb meem.
Peb cov khoom Cu-Ni yog engineered los leverage cov zoo. Muaj nyob rau hauv ntau hom (cov xov hlau, nplooj ntawv, cov raj) thiab nickel compositions, lawv yog precision-tsim kom tau raws li nruj kev lag luam qauv. Txawm hais tias rau kev tsim khoom hauv dej hiav txwv, kev ua tshuaj lom neeg, lossis cov tshuab ua haujlwm, peb cov khoom Cu-Ni xa kev ntseeg tau, kev ua haujlwm ntev, thiab kev ua haujlwm zoo uas cov tooj liab ntshiab tsis tuaj yeem sib xws. Xaiv Cu-Ni rau cov ntawv thov uas qhov ua tau zoo hauv cov xwm txheej hnyav tsis tuaj yeem sib tham tau - thiab ntseeg peb cov khoom kom tshaj qhov koj xav tau.
