Zirconated tungsten electrodesyog cov khoom siv electrode siv hauv TIG (tungsten arc vuam) thiab GTAW (gas tungsten arc vuam) cov txheej txheem. Nws yog ua los ntawm ib qho hlau alloy ntawm tungsten thiab zirconium, uas ua rau nws muaj cua sov-resistant thiab muaj zog dua li ntshiab tungsten electrodes. Nws muaj kev ruaj ntseg zoo arc thiab zoo dua arc pib ua haujlwm thaum vuam, thiab nws kuj tsis tshua muaj oxidation lossis corrosion dua electrodes ua los ntawm lwm cov ntaub ntawv. Zirconium tungsten electrodes tuaj yeem siv los txuas ntau yam hlau xws li titanium alloys, magnesium alloys, tooj liab alloys, thiab nickel alloys.
1. Technical Data
Zirconium tungsten electrodes yog electrodes rau TIG vuam, phau ntawv arc vuam, thiab plasma txiav. Cov hauv qab no yog nws cov khoom siv tshuaj thiab lub cev:
Lub cev muaj zog
- Ceev: 5.4-5.5g/cm³
- Tensile zog: 1500-1900MPa
- Bending zog: 1350-1750MPa
- Conductivity: 16.3-18.1μΩ·cm
- Melting point: 3422 degree
- Coefficient ntawm thermal expansion: 4.9 × 10 ^ -6 / degree
Feem ntau, zirconiaated tungsten electrodes muaj oxidation tsis kam, siab zog, thiab zoo hluav taws xob conductivity, thiab yog haum rau argon arc vuam, phau ntawv arc vuam, thiab plasma txiav ua hauj lwm nyob rau hauv high-kub ib puag ncig.
2. Cov txheej txheem tsim khoom
Hauv qab no yog cov txheej txheem tsim cov zirconium tungsten electrodes
1) Kev npaj cov khoom siv: Npaj siab purity zirconium hmoov, tungsten hmoov, thiab lwm yam tshuaj uas yuav tsum tau ntxiv, xws li av, oxides, thiab carbon.
2) Kev sib xyaw: Sib tov cov ntaub ntawv xav tau hauv ib qho kev faib ua feem thiab ntxiv cov nplaum txaus. Qhov sib tov tuaj yeem ua tiav hauv lub pob zeb lossis ziab hauv chav ziab.
3) Ua cov electrodes: Compress qhov sib tov rau hauv cov duab uas xav tau, thiab tom qab ntawd sinter lub crucible los yog kub kub kom tau cov electrode.
4) Sib tsoo: Sib tsoo cov electrodes precisely. Qhov no yog ib kauj ruam tseem ceeb raws li nws txiav txim siab qhov nto tiav thiab qhov tseeb qhov tseeb ntawm cov electrodes.
5) Txheej: siv cov txheej txheem tshwj xeeb ntawm cov khoom siv electrode los txhim kho nws lub neej kev pabcuam thiab kev ua haujlwm vuam.
3. Lub hauv paus ntsiab lus ua haujlwm
Cov saum toj no yog cov txheej txheem ntawm zirconiaated tungsten electrodes. Cov txheej txheem no yuav tsum muaj kev tswj hwm nruj heev thiab kuaj xyuas kom ntseeg tau tias cov khoom tsim tawm tuaj yeem ua tau raws li cov qauv tsim nyog thiab cov neeg siv khoom xav tau.
Zirconium tungsten electrodes ua hauj lwm los ntawm kev siv lawv lub siab melting point thiab tsis tshua muaj hluav taws xob emission zog kom ua tiav arc tu thiab stabilization. Cov electrode no yog tsim los ntawm cov ntshiab tungsten thiab zirconium, thiab zirconium yog siv los ua ib qho ntxiv los txhim kho cov thermal stability thiab electron emission zog ntawm tungsten electrodes, ua rau lawv tiv taus kev sib txhuam thiab kub.
Thaum cov electrode no hu rau saum npoo ntawm lub workpiece, vim nws qhov siab melting point thiab tsis tshua muaj hluav taws xob emission fais fab, nws muaj peev xwm tsim ib tug ruaj khov arc ntawm qhov kub thiab txias, yog li cua sov ntawm lub workpiece mus rau ib tug txaus kub kom yaj los yog fuse nws. Piv nrog rau lwm cov tungsten electrodes, tungsten electrodes muaj cov cua sov zoo dua thiab arc stability thiab muaj peev xwm tswj tau qhov chaw ruaj khov nyob rau hauv high voltage thiab siab tam sim no. Qhov no ua rau lawv muaj txiaj ntsig hauv ntau qhov kev siv vuam thiab txiav.
4. Daim ntawv thov teb
zirconiaated tungsten electrodes (Zr-W) feem ntau yog siv nyob rau hauv high-temperature daim ntaub ntawv, piv txwv li nyob rau hauv lub sij hawm ntev ntawm kev ruaj khov arc vuam thiab txiav cov hauj lwm yuav tsum tau, thiab qhov twg zoo welds yuav tsum tau. Hauv qab no yog daim ntawv thov teb ntawm Zr-W electrodes:
- Kev lag luam aerospace: Hauv kev lag luam aerospace, Zr-W electrodes yuav tsum tau vuam cov khoom xws li aerospace cav, missiles, aerospace tsheb, thiab lwm yam khoom siv kub.
- Kev lag luam tshuaj: Zr-W electrodes tuaj yeem siv rau vuam thiab txiav hauv petrochemical, tshuaj, thiab lwm yam txheej txheem kub.
- Kev lag luam kho mob: Zr-W electrodes yog siv los tsim cov khoom siv kho mob thiab cov cuab yeej phais.
- Kev lag luam semiconductor: Hauv cov txheej txheem tsim khoom semiconductor, Zr-W electrodes tuaj yeem siv rau vuam thiab txiav.
