Kev sib xyaw tooj liab thiab npib tsib xee tsim ib tsev neeg ntawm cov alloys hu ua tooj liab-nickel (Cu-Ni) alloys, uas muab cov khoom zoo tshaj plaws ntawm ob qho tib si hlau los tsim cov khoom siv nrog cov yam ntxwv tshwj xeeb. Qhov fusion no hloov pauv lawv tus kheej qhov zoo rau hauv kev sib koom ua ke ntawm qhov zoo, uaCu-Ni alloysindispensable nyob rau hauv ntau yam kev lag luam daim ntawv thov - thiab peb cov khoom Cu-Ni yog engineered los ua kom cov txiaj ntsig zoo tshaj plaws.
Nyob rau theem molecular, tooj liab thiab npib tsib xee tsim ib qho kev daws teeb meem thaum sib xyaw, txhais tau tias cov atoms ntawm ob qho tib si hlau faib sib npaug thoob plaws hauv cov khoom. Qhov no uniformity yog qhov tseem ceeb rau lawv cov khoom txhim khu kev qha. Ntshiab tooj liab yog cov conductive heev thiab malleable tab sis tsis muaj corrosion kuj, thaum npib tsib xee yog tawv thiab corrosion-resistant tab sis tsawg conductive. Ua ke, lawv tsim ib yam khoom uas sib npaug cov yam ntxwv no.
Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov khoom sib tov no yog superior corrosion kuj. Cov ntsiab lus npib tsib xee nyob rau hauv Cu-Ni alloys ua cov txheej txheej tuab, tiv thaiv cov khoom siv los ntawm Salverwater, acids, thiab kev lag luam tshuaj. Qhov no ua rau Cu-Ni alloys zoo tagnrho rau thaj chaw hauv hiav txwv, xws li nkoj hulls, seawater piping, thiab offshore platforms, qhov twg ntshiab tooj liab yuav sai sai corrode. Peb cov khoom Cu-Ni, tsim rau cov teeb meem hnyav no, tiv taus pitting, crevice corrosion, thiab yaig, kom ntseeg tau lub sijhawm ntev.
Mechanical zog kuj tau txais kev txhawb nqa los ntawm kev sib xyaw tooj liab-nickel. Cu-Ni alloys muaj zog thiab nyuaj dua li cov tooj liab ntshiab, thaum khaws cov khoom zoo. Qhov no tso cai rau lawv tiv taus kev ntxhov siab hauv cov khoom siv xws li twj, li qub, thiab cov khoom siv hluav taws xob. Tsis zoo li cov tooj liab ntshiab, uas tuaj yeem deform nyob rau hauv cov khoom hnyav, peb cov Cu-Ni cov xov hlau thiab cov nplooj ntawv tuav cov qauv kev ncaj ncees txawm tias nyob rau hauv kev xav tau, txo cov kev xav tau ntawm kev saib xyuas.
Thermal thiab hluav taws xob conductivity tseem impressive nyob rau hauv Cu-Ni alloys, txawm me ntsis qis dua tooj liab ntshiab. Qhov no ua rau lawv tsim nyog rau cov khoom siv hluav taws xob sib txawv thiab cov khoom siv hluav taws xob uas muaj kev tiv thaiv corrosion yog qhov tseem ceeb xws li conductivity. Piv txwv li, hauv cov nroj tsuag desalination, peb cov hlab Cu-Ni tau zoo hloov cov cua sov thaum tiv thaiv cov corrosive los ntawm cov dej ntsev.
Peb cov khoom Cu-Ni muaj nyob rau hauv ntau qhov sib xyaw, nrog cov ntsiab lus nickel xws li 10% txog 30%,haum rau kev thov tshwj xeeb. Txawm hais tias koj xav tau cov xov hlau nyias nyias rau qhov tsis sib xws lossis cov nplooj ntawv tuab rau cov qauv hnyav, peb cov khoom siv precision ua kom zoo thiab ua haujlwm zoo. Los ntawm kev siv cov txiaj ntsig tshwj xeeb ntawm kev sib xyaw tooj liab-nickel, peb cov khoom xa tuaj yeem muaj kev ntseeg siab thiab siv tau ntev nyob rau hauv ib puag ncig uas cov hlau ntshiab luv luv.
