Vim li cas Ntxiv Cov Nyiaj Tau Los Ntawm Nickel rau Cov Nyiaj Sib Txuas?

1. Kev Txhim Kho Kev Ua Haujlwm: Los ntawm Ntshiab Nyiaj rau Nyiaj -Nickel Alloy

Ntxiv ib qho me me ntawm npib tsib xee (feem ntau 5% mus rau 40%) rau Silver Alloy Rivets ua rau muaj ntau yam kev txhim kho. Ua ntej, npib tsib xee refines lub grain qauv ntawm cov nyiaj, zoo nce cov khoom hardness thiab lub zog. Qhov no ua rau nyiaj -nickel alloy tiv tauj tuaj yeem pom kev hnav zoo dua thaum lub sijhawm ua haujlwm tsis tu ncua, txuas ntxiv lawv lub neej kev pabcuam. Thib ob, npib tsib xee txhim kho cov nyiaj tiv thaiv arc hlawv- tawm thiab electro- corrosion. Arcing thaum lub sij hawm hloov tuaj yeem ua rau qhov chaw sib cuag, tab sis nyiaj -nickel alloys zoo dua tuaj yeem tiv taus qhov kev puas tsuaj no, tswj kev ncaj ncees ntawm kev sib cuag. Tsis tas li ntawd, nyiaj -nickel alloys muaj zog tiv thaiv cov hlau hloov, txo kev sib cuag tsis ua hauj lwm los ntawm cov khoom tsiv teb tsaws nyob rau hauv DC tej yam kev mob.

Txawm hais tias qhov sib ntxiv ntawm cov nickel me ntsis nce kev tiv thaiv kev tiv thaiv, qhov tseem ceeb rau Silver Alloy Contacts tseem nyob rau theem qis thiab ruaj khov, uas yog qhov tseem ceeb rau kev ua kom ntseeg tau ntawm kev sib txuas hluav taws xob. Nyob rau tib lub sijhawm, nyiaj -nickel alloys tswj cov hluav taws xob zoo thiab thermal conductivity, ua haujlwm zoo tam sim no thiab dissipating tshav kub, tiv thaiv cov cua sov hauv zos.

2. Cov txheej txheem npaj thiab cov khoom siv

Txij li cov nyiaj thiab npib tsib xee yog qhov tsis sib haum xeeb hauv lub xeev, nyiaj -nickel alloys feem ntau yog npaj siv hmoov metallurgy. Cov txheej txheem ib txwm muaj xws li tshuaj co- tso nyiaj los yog cov txheej txheem tshuaj los npaj cov khoom sib xyaw lossis coated nyiaj-nickel hmoov, tab sis cov no nyuaj thiab kim heev. Nrog rau kev txhim kho thev naus laus zis, kev siv tshuab atomization tam sim no tau siv ntau dua kom tau txais cov hmoov zoo heev, uas tom qab ntawd sib tov, nias, sintered, thiab extruded los tsim cov nyiaj ruaj khov -nickel alloys. Nyob rau hauv xyoo tas los no, daim ntawv thov nyiaj -nickel co- tshuaj tsuag hmoov npaj thiab cov cuab yeej siv tshuab alloying tau txhim kho cov khoom siv ntxiv. Tsis tas li ntawd, ntxiv me me ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb rau cov hlau kuj tuaj yeem txhim kho tag nrho kev ua haujlwm ntawm cov nyiaj hluav taws xob tiv tauj.

Silver-nickel alloys muaj qhov zoo ductility thiab machinability, yooj yim rau fabrication ntawm kev sib cuag ntawm ntau yam duab thiab ntau thiab tsawg. Lawv lub cev muaj zog, xws li ntom, hardness, thermal conductivity, thiab resistivity, sib txawv nrog cov ntsiab lus nickel. Piv txwv li, nce nickel cov ntsiab lus txhim kho cov alloy lub hardness thiab lub zog, tab sis sib raug zoo txo ​​hluav taws xob thiab thermal conductivity. Yog li ntawd, nyob rau hauv kev siv tswv yim, cov ntsiab lus nickel tsim nyog yuav tsum raug xaiv raws li kev ua haujlwm tshwj xeeb rau kev sib cuag hluav taws xob.

3. Cov cheeb tsam thov thiab xaiv cov lus pom zoo

Silver alloys tiv tauj, raws li cov khoom siv hluav taws xob tiv tauj, yog siv dav hauv ntau yam khoom siv hluav taws xob tsawg-voltage. Cov kev siv feem ntau muaj xws li ntau yam keyboards, controllers, voltage regulators, circuit breakers, automotive electronic components, thiab magnetic starters. Qhov kev xaiv ntawm cov ntsiab lus nickel sib txawv nyob ntawm qhov kev thov scenario. Piv txwv li, AgNi10 (muaj 10% npib tsib xee) feem ntau siv hauv AC contactors hauv qab 20A, thaum AgNi (15-40%) nrog cov ntsiab lus nickel ntau dua tuaj yeem tiv taus ntau dua.

Thaum xaiv nyiaj cadmium oxide khoom tiv tauj, yam xws li kev khiav hauj lwm tam sim no, hom load, hloov zaus, thiab ib puag ncig yuav tsum tau txiav txim siab. Rau lub teeb rau nruab nrab load daim ntaub ntawv, nyiaj -nickel alloys tseem yog ib qho kev xaiv zoo tshaj vim lawv cov nqi zoo heev -effectiveness. Txawm li cas los xij, nyob rau hauv siab tam sim no, siab inrush tam sim no, los yog hnyav load, lwm yam ntaub ntawv, xws li nyiaj tin oxide (AgSnO₂), tej zaum yuav tsum tau txiav txim siab kom tau zoo dua tiv thaiv arc yaig thiab vuam.

4. Yav tom ntej Outlook thiab Technology Innovation

Nrog rau kev loj hlob sai ntawm lub zog tshiab tsheb, cov phiajcim ntse, thiab lwm qhov chaw, kev xav tau ntau dua tau muab tso rau ntawm Silver hluav taws xob cov ntaub ntawv sib cuag. Cov kws tshawb nrhiav niaj hnub tshawb nrhiav cov qauv tsim microstructure tshiab txhawm rau txhim kho kev ua haujlwm ntawm cov nyiaj -nickel alloys. Piv txwv li, los ntawm kev tsim cov txheej txheem sib xyaw ua ke nrog kev sib koom ua ke nrog peb - qhov ntev ntawm cov nickel txuas ntxiv thiab cov nickel dispersed, qhov teeb meem ntawm nickel particle tsiv teb tsaws hauv cov ntaub ntawv ib txwm muaj peev xwm daws tau zoo, txhim kho cov khoom tiv thaiv arc yaig.

Tsis tas li ntawd, kev qhia cov ntaub ntawv tshiab xws li carbon nanotubes li "cov kav hlau txais xov" los tsim cov kev sib txuas txuas txuas txuas ntxiv kuj tseem yog ib qho kev txiav - ntug kev tshawb fawb txog kev txhim kho conductivity thiab mechanical zog ntawm nyiaj -nickel alloys. Cov kev tsim kho thev naus laus zis no yuav muab lub hauv paus tseem ceeb theoretical thiab cov txheej txheem kev taw qhia rau kev txhim kho cov ntaub ntawv tom ntej -Silver Contact Points.
