Nickel-chromium alloy, ib qho hlau uas tsis muaj hlau nplaum uas muaj nickel, chromium thiab hlau, tau txais kev hwm heev hauv kev lag luam niaj hnub no rau nws cov yam ntxwv zoo tshaj plaws. Nws paub txog nws qhov kev tiv taus kub siab thiab kev tiv taus corrosion zoo heev. Qhov kev sib xyaw ua ke ntawm cov yam ntxwv no ua rau nws yog cov khoom siv ntau yam nrog ntau yam kev siv tseem ceeb hauv ntau yam lag luam.
Hauv kev tsim cov khoom cua sov,cov hlau nickel-chromiumUa lub luag haujlwm tseem ceeb. Ua tsaug rau lawv qhov chaw yaj siab thiab kev tiv thaiv oxidation zoo heev, Nichrome cov xov hlau feem ntau siv rau hauv txhua yam khoom siv hluav taws xob cua sov. Cov khoom siv hauv tsev xws li lub tshuab ci mov, lub tshuab ziab plaub hau, qhov cub, thiab lwm yam tsis tuaj yeem sib cais los ntawm kev koom tes ntawm Nichrome cov ntsiab lus cua sov. Piv txwv li, qhov cub zoo yuav tsum muaj peev xwm tswj tau qhov kub thiab txias ruaj khov rau lub sijhawm ntev, thiab Nichrome muaj peev xwm ua tau li ntawd. Nws lub peev xwm los tiv taus qhov kub thiab txias yam tsis yooj yim deformed lossis corroded muab qhov cub nrog kev ua haujlwm cua sov txhim khu kev qha.
Nichrome kuj tseem ua tau zoo hauv kev tsim cov xov hlau tiv taus thiab cov resistors. Nws qhov kev tiv taus hluav taws xob siab ua rau nws yog cov khoom siv zoo heev rau cov khoom siv cua sov tiv taus hauv cov khoom siv xws li cov cub tawg, cov kilns thiab cov cua sov hluav taws xob. Hauv kev tsim khoom lag luam, kev tswj qhov kub kom meej yog qhov tseem ceeb. Nichrome lub peev xwm los tsim cua sov kom zoo thiab sib npaug ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev tswj qhov kub kom meej thiab kev ruaj khov siab. Piv txwv li, hauv qee qhov kev lag luam tsim khoom meej, xws li kev tsim cov khoom siv hluav taws xob, kev tswj qhov kub kom nruj yog qhov yuav tsum tau ua kom ntseeg tau tias cov khoom zoo thiab kev ua tau zoo. Nichrome tsis kam xov hlau tuaj yeem muab qhov chaw cua sov ruaj khov, pab ua tiav kev tswj qhov kub kom meej, yog li txhim kho cov khoom tsim tawm.
Hauv kev ua hlau metallurgy, NiCr alloys ua lub luag haujlwm tseem ceeb. Kev tsim cov hlau thiab lwm yam hlau feem ntau xav tau kev kho kub siab, thiab Nichrome ua tau raws li qhov xav tau no. Nws yog siv rau hauv cov txheej txheem xws li annealing, quenching thiab tempering ntawm cov hlau. Cov khoom cua sov tswj tau ntawm Ni-Cr alloys ua rau lawv yog ib qho tseem ceeb ntawm cov txheej txheem tseem ceeb no. Thaum lub sijhawm annealing,Cov hlau NiCrmuab cua sov sib npaug, pab txo qhov kev ntxhov siab sab hauv thiab txhim kho qhov tawv thiab kev siv tshuab ntawm cov hlau. Thaum lub sijhawm quenching thiab tempering, nws sai sai ua kom cov hlau sov mus rau qhov kub tshwj xeeb thiab ruaj khov, txhim kho cov khoom xws li qhov nyuaj thiab lub zog. Nichrome lub peev xwm los tiv taus qhov kub siab thiab tiv taus oxidation ua kom muaj cov txheej txheem cua sov sib npaug thiab sib xws, ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo thiab kev ncaj ncees ntawm cov khoom hlau.
Kev lag luam tsheb kuj yog ib qho ntawm cov chaw thov tseem ceeb tshaj plaws rau Nichrome alloys. Tshwj xeeb tshaj yog nyob rau hauv kev tsim cov tshuab hluav taws xob diesel thiab cov ntsaws preheat, NiCr alloys ua lub luag haujlwm tseem ceeb. Qhov kev tiv thaiv hluav taws xob siab thiab kev ruaj khov thermal ntawm NiCr alloys ua rau lawv zoo tagnrho rau kev tsim cov khoom siv hluav taws xob uas tuaj yeem tiv taus cov xwm txheej hnyav hauv lub cav. Thaum lub sijhawm ua haujlwm ntawm lub cav, lub kaw lus hluav taws xob yuav tsum tsim kom muaj hluav taws xob kub siab, siab siab hauv ib pliag kom hlawv cov roj sib tov. Cov khoom siv hluav taws xob Nichrome tuaj yeem ua haujlwm ruaj khov hauv qab cov xwm txheej hnyav, ua kom lub cav pib txhim khu kev qha thiab ua haujlwm tau zoo. Tsis tas li ntawd, lub ntsaws preheat kuj yog ib qho tseem ceeb hauv lub cav diesel, uas yuav tsum tau ua kom sov sai sai ntawm qhov kub qis kom pab lub cav pib du. Cov yam ntxwv sov sai ntawm nickel-chromium alloy ua rau nws yog cov khoom siv zoo tagnrho rau cov ntsaws preheat, muab rau kev ua haujlwm ib txwm ntawm cov cav diesel hauv huab cua txias.
Kev siv dav dav ntawm nickel-chromium alloy tsis yog vim nws qhov kev ua tau zoo tshwj xeeb xwb, tab sis kuj ua tsaug rau kev nce qib tas mus li thiab kev tsim kho tshiab ntawm cov thev naus laus zis niaj hnub. Nrog rau kev txhim kho ntawm cov khoom siv science, tib neeg muaj kev nkag siab tob txog kev ua tau zoo thiab kev siv ntawmnickel-chromium alloyCov kws tshawb nrhiav txuas ntxiv tshawb nrhiav cov qauv tshiab thiab cov txheej txheem tsim khoom kom txhim kho kev ua tau zoo thiab kev hloov pauv ntawm Ni-Cr alloys. Piv txwv li, los ntawm kev ua kom zoo dua qhov sib piv ntawm nickel, chromium thiab hlau hauv cov alloy, kev ua tau zoo ntawm Ni-Cr alloys xws li kev tiv taus cua sov, kev tiv taus corrosion thiab kev tiv taus hluav taws xob tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm ntau yam kev siv.
Tib lub sijhawm, nrog rau kev paub txog kev tiv thaiv ib puag ncig, tib neeg kuj tau muab cov kev cai siab dua rau kev ua haujlwm ib puag ncig ntawm cov ntaub ntawv. Nickel-chromium alloy hauv kev tsim khoom thiab siv cov txheej txheem kuj tseem niaj hnub mus rau qhov kev coj ua zoo rau ib puag ncig. Piv txwv li, qee lub tuam txhab tau pib siv cov txheej txheem tsim khoom huv dua los txo cov pa phem rau ib puag ncig. Tsis tas li ntawd, nichrome alloys muaj qee qhov peev xwm hauv kev rov ua dua tshiab. Vim nws muaj nqis siab thiab kev rov ua dua tshiab zoo, cov khoom pov tseg nichrome alloy tuaj yeem rov ua dua tshiab thiab rov siv dua los txo cov khoom pov tseg thiab kev ua qias tuaj rau ib puag ncig.
