Daim ntawv thov teb ntawm ntshiab tungsten daim hlau yog dav heev, feem ntau suav nrog cov hauv qab no:
Resistance vuam tshuab electrode: Ntshiab tungsten qws yog dav siv nyob rau hauv zus tau tej cov welding tshuab electrodes vim nws tsis tshua muaj thermal expansion, zoo thermal conductivity, txaus kuj, thiab siab elastic modulus. cov
Sputtering lub hom phiaj cov khoom: Cov tungsten rods ntshiab kuj siv los ua sputtering lub hom phiaj, uas yog lub cev vapor deposition txheej txheem siv los npaj cov ntaub ntawv nyias. cov
Qhov hnyav thiab cua sov cov ntsiab lus: Ntshiab tungsten rods kuj tseem siv tau los ua qhov hnyav thiab cua sov, tsim rau cov ntawv thov uas xav tau kev kub ceev thiab kub ua haujlwm. cov
Lub cev tseem ceeb ntawm kev tshaj lij darts: Tungsten alloy yog siv los ua lub cev tseem ceeb ntawm darts vim nws qhov siab ceev thiab lub cev zoo.
Qhov kub ntawm lub phaj tungsten thaum kub dov yog qhov tseem ceeb thiab yuav tsum tau ua tib zoo tswj thiab saib xyuas. Nov yog qee cov lus ceeb toom txog qhov kub thiab txias:
1. Qhov zoo tshaj qhov kub thiab txias: tungsten daim hlau yuav tsum tau rhuab mus rau qhov kub thiab txias kom yooj yim rau cov txheej txheem kub dov. Qhov ntsuas kub no feem ntau yog txiav txim siab raws li cov khoom siv ntawm tungsten thiab cov khoom siv kho kom zoo ntawm cov khoom kawg.
2. Tsis txhob overheating: overheating ntawm tungsten daim hlau tuaj yeem ua rau muaj kev hloov pauv tsis zoo hauv lawv cov microstructure thiab txhua yam khoom. Nws yog ib qho tseem ceeb kom tsis txhob siab tshaj qhov kub siab tshaj plaws los tiv thaiv cov khoom degradation.
3. Cov cua kub tsis sib xws: xyuas kom meej tias cov phaj tungsten cua sov sib npaug yog qhov tseem ceeb rau kev tuav cov khoom zoo ib yam thoob plaws tag nrho saum npoo. Kev hloov kub tuaj yeem ua rau tsis sib xws thaum lub sij hawm dov, ua rau cov khoom tsis sib xws.
4. Txias tus nqi: Tom qab kub dov, tungsten phaj yuav tsum tau txias ntawm tus nqi tswj kom ua tau raws li qhov xav tau microstructure thiab txhua yam khoom. Kev txias txias los yog txias tsis sib xws tuaj yeem ua rau muaj kev ntxhov siab thiab deformation hauv cov khoom kawg.
5. Kev saib xyuas thiab kev tswj hwm: Kev ntsuas kub tsis tu ncua thaum lub sij hawm kub dov yog qhov tseem ceeb rau kev hloov kho lub sijhawm tiag tiag thiab tswj cov khoom tsim nyog. Cov txheej txheem ntsuas kub siab tshaj plaws tuaj yeem siv los xyuas kom meej cov txheej txheem cua sov thiab cua txias.
Zuag qhia tag nrho, qhov kub ntawm lub phaj tungsten thaum lub sij hawm kub dov ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kawg ntawm cov khoom dov, thiab kev saib xyuas yuav tsum tau ua kom tswj tau qhov ntsuas kub kom tsim nyog thoob plaws hauv cov txheej txheem.
Muaj ntau qhov laj thawj rau kev tawg hauv kev ua cov tungsten ntshiab, suav nrog:
1. Brittleness: Ntshiab tungsten yog inherently brittle, tshwj xeeb tshaj yog nyob rau hauv chav tsev kub. Thaum lub sij hawm ua xws li kub dov los yog txias ua hauj lwm, cov khoom yuav tawg los yog tawg vim nws brittleness.
2. High hardness: Tungsten muaj hardness siab, thiab yog hais tias cov cuab yeej thiab cov cuab yeej tsis tsim los tuav cov khoom nyuaj no, nws yuav yooj yim tawg thiab tawg thaum lub sij hawm machining txheej txheem.
3. Kev ntxhov siab ntau: Kev tuav tsis raug lossis ua tiav ntawm cov paib ntshiab tungsten yuav ua rau muaj kev ntxhov siab hauv cov khoom, ua rau kev pib thiab nthuav dav ntawm cov kab nrib pleb, thiab thaum kawg tawg.
4. Lub lubrication tsis txaus: Lub lubrication tsis txaus thaum lub sijhawm ua haujlwm xws li kev txiav, khoov lossis kev sib sau tuaj yeem ua rau muaj kev sib txhuam thiab cua sov, ua rau lub zog tsis muaj zog thiab muaj peev xwm tawg ntawm tungsten phaj.
5. Kev kho cua sov tsis zoo: Kev kho cua sov tsis sib haum lossis tsis raug ntawm cov paib ntshiab tungsten tuaj yeem ua rau muaj kev ntxhov siab sab hauv, cov qauv nplej tsis sib xws, lossis embrittlement, tag nrho cov no tuaj yeem ua rau tawg hauv cov kauj ruam tom ntej.
6. Cov cuab yeej hnav: Siv cov cuab yeej hnav lossis tsis raug thaum lub sijhawm ua haujlwm lossis kev ua haujlwm tuaj yeem ua rau cov cuab yeej muaj kev ntxhov siab thiab ua kom muaj cua sov, ua rau muaj qhov tsis xws luag thiab muaj peev xwm tawg ntawm tungsten phaj.
Txhawm rau txo qhov tawg thaum lub sij hawm ua tiav cov phaj tungsten ntshiab, cov yam ntxwv ntawm cov khoom yuav tsum tau ua tib zoo xav, cov cuab yeej tsim nyog thiab cov cuab yeej siv yuav tsum tau siv, lubrication kom raug, cov txheej txheem yuav tsum tau tswj, thiab cov txheej txheem kho cua sov tsim nyog yuav tsum tau ua kom txo qis sab hauv. kev ntxhov siab thiab tswj cov khoom siv. ntawm kev ncaj ncees.
