Txhim Kho Kev Ua Haujlwm Nrog Cov Hlau Hlau Nickel Alloy Siab

Hauv lub ntiaj teb ceev ceev ntawm kev vuam thiab cladding, cov kws tshaj lij nkag siab txog qhov tseem ceeb ntawm kev siv cov khoom zoo kom ua tiav cov txiaj ntsig zoo tshaj plaws. Qhov no yog qhov uas cov hlau nickel alloy siab tuaj rau hauv kev ua si. Tsim tshwj xeeb rau kev vuam thiab cladding nickel-based alloys xws li 625 lossis cov ntaub ntawv zoo sib xws, cov hlau no yog tsim los ua kom dhau qhov kev cia siab hauv kev ua tau zoo, kev ruaj khov thiab kev hloov pauv ntau yam. Tsim los xa cov vuam huv dua, zoo dua hauv kev tsim qauv ruaj khov, cov hlau no sawv tawm hauv kev ua lag luam rau nws cov ductility zoo dua thiab ci ntsa iab welds.

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawmhlau nickel siab alloy vuam hlauyog nws cov khoom siv kho tshuab zoo heev ntawm ob qho tib si kub thiab qis. Txawm hais tias ib puag ncig zoo li cas los xij, cov kws tshaj lij tuaj yeem paub tseeb tias cov hlau vuam no yuav txuas ntxiv ua kom pom kev ua tau zoo thiab kev ua haujlwm zoo. Tsis tas li ntawd, cov hlau vuam no muaj kev tiv thaiv zoo rau kev xeb thiab kev ntxhov siab, ua rau nws zoo tagnrho rau cov haujlwm xws li kev lag luam tshuaj lom neeg, kev tsim kho hauv hiav txwv, cov khoom siv nuclear reactor, aerospace thiab cov khoom siv tswj hwm nom tswv.

Kev tswj hwm kev ncaj ncees thiab kev ua tau zoo yog qhov tseem ceeb thaum ua haujlwm nrog cov hlau nickel siab thiab cov ntaub ntawv zoo sib xws.Cov xov hlau nickel siab heevtau tsim los kom ntseeg tau tias muaj cov txiaj ntsig zoo ib yam txawm tias nyob rau hauv cov xwm txheej nyuaj. Cov hlau ua haujlwm dhau qhov kub thiab txias pom zoo los ntawm cryogenic mus rau 540 ° C, muab kev thaj yeeb nyab xeeb hauv kev tiv thaiv kev hloov pauv kub. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov tseem ceeb qhov twg kev ruaj khov yog qhov tseem ceeb rau kev ua haujlwm txhim khu kev qha.

Tsis tas li ntawd,hlau nickel siab alloy vuam hlauua rau muaj kev tsim khoom thiab kev ua haujlwm zoo dua. Nrog nws cov thev naus laus zis mapping zoo, nws ua rau cov txheej txheem soldering du thiab tsis muaj teeb meem, txo qhov yuam kev thiab rov ua haujlwm. Qhov no tsis yog tsuas yog txuag lub sijhawm muaj nqis xwb, tab sis kuj txo cov khoom pov tseg, ua rau nws yog qhov kev xaiv pheej yig rau ntau yam lag luam. Qhov kawg yog qhov tseeb, huv si welds nrog ductility zoo heev, ua kom ntseeg tau tias kev ua haujlwm ntev txawm tias nyob rau hauv cov xwm txheej nyuaj.

Hauv kev xaus lus, cov electrodes hlau nickel siab muaj ntau yam zoo rau cov kws tshaj lij hauv kev lag luam vuam thiab cladding. Nws lub peev xwm los yooj yim vuam thiab clad nickel-based alloys, suav nrog 625, muab kev daws teeb meem txhim khu kev qha rau ntau yam kev siv. Los ntawm kev xa cov welds ci ntsa iab, zoo rau kev ua kom pom cov khoom siv kho tshuab zoo dua ntawm qhov kub thiab txias heev, cov hlau no ua rau cov kws tshaj lij ua tiav cov txiaj ntsig zoo dua. Nrog nws lub peev xwm los tiv taus pitting thiab kev ntxhov siab corrosion, nws tau ua pov thawj tias yog qhov kev xaiv ruaj khov thiab txhim khu kev qha. Kev siv ntawmcov xov hlau nickel siab heevqhib cov cib fim tshiab thiab ua kom tiav cov haujlwm hauv ntau qhov chaw xws li cov txheej txheem tshuaj lom neeg, kev tsim kho dej hiav txwv thiab kev tsav dav hlau.
