Thaum sawv ntxov ntawm qhov kev tshwm sim ...Nyeem ntxiv -
Lawv ua li cas zirconia?
Zirconia, tseem hu ua zirconium dioxide, feem ntau ua tiav siv txoj kev hu ua "kev ua hmoov nplej." Qhov no suav nrog ob peb kauj ruam, suav nrog: 1. Calcining: Cua sov zirconium tebchaw mus rau qhov kub thiab txias los tsim zirconium oxide hmoov. 2. Sib tsoo: Sib tsoo cov calcined...Nyeem ntxiv -
Dab tsi yog qhov txawv ntawm zirconated thiab ntshiab tungsten?
Lub ntsiab sib txawv ntawm zirconium electrodes thiab ntshiab tungsten electrodes yog lawv muaj pes tsawg leeg thiab kev ua tau zoo yam ntxwv. Pure tungsten electrodes yog tsim los ntawm 100% tungsten thiab feem ntau yog siv rau hauv kev siv vuam nrog cov ntaub ntawv tsis tseem ceeb xws li carbon steel thiab stainle ...Nyeem ntxiv -
Yuav ua li cas tshwm sim rau titanium crucible thaum kub siab?
Thaum kub kub, titanium crucibles pom zoo thermal stability thiab tsis kam mus deformation. Titanium muaj qhov siab melting point, yog li titanium crucibles tuaj yeem tiv taus cua sov yam tsis muaj melting lossis deforming. Tsis tas li ntawd, titanium oxidation kuj thiab tshuaj inertnes ...Nyeem ntxiv -
Dab tsi yog lub hom phiaj sputtering?
Sputter lub hom phiaj yog cov khoom siv los tso cov yeeb yaj kiab nyias mus rau hauv cov substrates thaum lub cev vapor deposition (PVD) txheej txheem. Lub hom phiaj cov khoom yog bombarded nrog high-zog ions, ua rau atoms yuav ejected los ntawm lub hom phiaj nto. Cov tshuaj txau no ces muab tso rau hauv substrate, rau ...Nyeem ntxiv -
Dab tsi yog hex bolts siv rau?
Hexagonal bolts yog siv los txuas cov hlau txuas ua ke. Lawv feem ntau siv rau hauv kev tsim kho, tshuab thiab kev siv tsheb. Lub bolt lub taub hau hex tso cai rau kom yooj yim zawm thiab loosening nrog ib tug ciaj ntswj los yog lub qhov (socket), ua rau nws yog ib tug nrov xaiv rau kev ruaj ntseg cov khoom hnyav. Meas...Nyeem ntxiv -
Dab tsi yog tungsten siv rau hauv engineering?
Tungsten qhov chaw feem ntau yog tsim los ntawm cov txheej txheem hmoov metallurgy. Nov yog cov txheej txheem dav dav ntawm cov txheej txheem: 1. Kev tsim cov hmoov: tungsten hmoov yog tsim los ntawm kev txo cov tungsten oxide siv hydrogen lossis carbon ntawm qhov kub thiab txias. Lub resulting hmoov yog ces tshuaj ntsuam kom tau ...Nyeem ntxiv -
Dab tsi yog guidewire hauv cov cuab yeej kho mob?
Ib txoj hlua hauv cov khoom siv kho mob yog ib txoj hlua nyias, hloov tau yooj yim siv los coj thiab tso cov cuab yeej kho mob, xws li catheters, hauv lub cev thaum muaj ntau yam txheej txheem kho mob. Guidewires feem ntau yog siv nyob rau hauv minimally invasive thiab interventional txheej txheem kom dhau los ntawm cov hlab ntsha, hlab ntsha, thiab ...Nyeem ntxiv -
Cov hlau twg yog qhov zoo tshaj plaws rau lub thoob?
Cov hlau zoo tshaj plaws rau lub thoob yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov kev xav tau. Piv txwv li, stainless hlau feem ntau yog siv rau nws cov corrosion kuj thiab durability, ua rau nws tsim nyog rau daim ntaub ntawv uas lub chim yog raug rau hnyav ib puag ncig los yog corrosive cov ntaub ntawv. Txawm li cas los xij, lwm tus kuv ...Nyeem ntxiv -
Dab tsi yog tooj liab tungsten alloy?
Copper-tungsten alloy, tseem hu ua tungsten tooj liab, yog cov khoom siv sib xyaw ua ke nrog tooj liab thiab tungsten. Cov khoom xyaw feem ntau yog sib xyaw ntawm tooj liab thiab tungsten, feem ntau 10% mus rau 50% tungsten los ntawm qhov hnyav. Cov alloy yog tsim los ntawm cov hmoov hlau metallurgy txheej txheem uas tungsten hmoov ...Nyeem ntxiv -
Yuav ua li cas yog tooj liab tungsten?
Tooj tungsten feem ntau yog ua los ntawm cov txheej txheem hu ua infiltration. Nyob rau hauv cov txheej txheem no, tungsten hmoov yog tov nrog ib tug binder khoom los tsim ib lub cev ntsuab. Lub compact yog ces sintered los ua ib tug ntxeem tau tungsten skeleton. Cov pob txha tungsten ntxeem tau ces infiltrated nrog molten tooj liab unde ...Nyeem ntxiv -
Cov hlau twg muaj qhov siab tshaj plaws melting point thiab vim li cas?
Tungsten muaj qhov siab tshaj plaws melting point ntawm tag nrho cov hlau. Nws melting point yog kwv yees li 3,422 degrees Celsius (6,192 degrees Fahrenheit). Tungsten cov ntsiab lus melting siab heev tuaj yeem raug ntaus nqi rau ntau yam tseem ceeb: 1. Cov hlau nplaum muaj zog: Tungsten atoms tsim cov hlau nplaum muaj zog nrog eac ...Nyeem ntxiv
