Tungsten vs. Molybdenum: Yuav ua li cas xaiv cov hlau zoo rau siab -Tub kub rauv?

Hauv kev tsim, kev ua haujlwm, thiab kev saib xyuas ntawm lub tshuab nqus tsev vacuum thiab siab - qhov kub thiab txias, qhov kev xaiv ntawm cov ntaub ntawv thermal teb ncaj qha txiav txim siab txog kev pabcuam lub neej, kev ua haujlwm zoo, thiab kev ruaj ntseg ntawm cov khoom siv - seb nws yog cov khoom siv cua sov, cov khoom siv hluav taws xob, lossis cov khoom siv crucible, nws cov khoom ua tau zoo yog ua tiav rau kev tsim khoom. Raws li cov kev xaiv tseem ceeb hauv kev ua haujlwm siab - cov ntaub ntawv kub kub, tungsten thiab molybdenum yog hu ua "cov hnub qub ntxaib" ntawm cov hlau refractory, ob qho tib si muaj qhov zoo heev - qhov kub thiab txias, tab sis muaj qhov sib txawv tseem ceeb hauv cov xwm txheej, kev ua haujlwm nyuaj, thiab cov nqi peev.

Rau cov neeg yuav khoom txawv teb chaws thiab cov kws tsim khoom siv, yuav ua li cas xaiv qhov zoo tshaj plaws ntawm ob qho raws li kev ua haujlwm ntawm lawv tus kheej siab - qhov kub thiab txias tau dhau los ua tus yuam sij rau kev txhim kho cov khoom ruaj khov thiab tswj cov nqi tsim khoom. Tsab ntawv xov xwm no yuav qhia meej txog cov xwm txheej siv tau rau tungsten thiab molybdenum thoob plaws ntau qhov ntev, suav nrog kev ua haujlwm, kev ua haujlwm, nqi, thiab kev ua tau zoo, thiab muab cov ntaub ntawv tshaj lij rau kev xaiv cov khoom siv kub kub - kub.

1. Kev txwv kub-Tungsten raug xaiv rau ultra- daim ntawv thov kub, thaum molybdenum raug xaiv rau cov pa kub siab - daim ntawv thov kub.

Recrystallization brittleness yog hais txog kev hloov pauv ntawm cov nplej hauv cov khoom nyob rau hauv ntev - lub sij hawm siab - qhov kub thiab txias, uas ua rau txo qis ntawm cov khoom toughness thiab ua rau nws yooj yim rau tawg. Qhov no kuj yog vim li cas tseem ceeb vim li cas cov hlau refractory zoo ib yam ua rau tsis ua hauj lwm nyob rau hauv siab - qhov kub thiab txias.

Yog tias koj lub tshuab nqus tsev vacuum los yog siab -kub muaj qhov cub ua haujlwm ntawm qhov kub siab tshaj 2000 degree, xws li cov khoom siv rau sintering siab - cov ntaub ntawv kawg lossis smelting precious hlau, tungsten yog tib txoj kev xaiv.

Raws li cov hlau nrog lub siab tshaj plaws melting point nyob rau hauv cov xwm, tungsten tswj zoo heev structural stability thiab tsawg deformation txawm nyob rau hauv siab - kub ib puag ncig saum 2000℃. Nws yog qhov tshwj xeeb tshaj yog tsim rau kev tsim cov tub ntxhais cua sov (xws li tungsten twisted hlau thiab tungsten cua sov rods), tiv thaiv cov khoom tsis ua hauj lwm ntawm qhov kub thiab txias thiab ncua sij hawm ua haujlwm tas li ntawm cov khoom siv.

Yog tias koj cov cuab yeej ua haujlwm ntawm qhov kub ntawm 1100℃thiab 1800 degree, xws li lub tshuab nqus tsev vacuum brazing furnaces lossis hmoov metallurgy sintering furnaces, molybdenum lossis molybdenum alloys (lanthanum-} molybdenum Mo-La, TZM alloys) yog cov kev xaiv zoo tshaj.

Cov pa molybdenum muaj siab txaus siab -kub tsis kam los npog qhov kub thiab txias, thiab nws cov nqi qis dua li ntawm tungsten, ua rau nws tsim nyog rau kev tsim cov khoom xws li cov ntaub thaiv kub, molybdenum nkoj, thiab cov khoom txhawb nqa. Nws yog ib qho tseem ceeb tshwj xeeb uas yuav tsum nco ntsoov tias cov pa molybdenum yog qhov yooj yim rau recrystallization brittleness nyob rau hauv lub sij hawm ntev kub. Txawm li cas los xij, peb cov khoom siv lanthanum-molybdenum (Mo-}La) thiab TZM alloys, los ntawm kev kho tshwj xeeb alloying, tuaj yeem ua rau cov khoom siv rov ua dua tshiab, ua kom muaj txiaj ntsig zoo, kov yeej qhov teeb meem no, ua kom lub neej ntev ntawm cov khoom siv, thiab ua tau raws li qhov yuav tsum tau ua kom ntev - lub sij hawm siab - kub.

2. Machinability & Geometry-Molybdenum yog qhov nyiam rau cov khoom siv nyuaj.

Cov qauv tsim ntawm siab- qhov kub ntawm qhov cub feem ntau suav nrog cov txheej txheem nyuaj, xws li threaded fasteners, nyias-cov ntaub thaiv phab ntsa, thiab loj - thaj tsam cov ntxaij vab tshaus. Molybdenum muaj qhov toughness zoo dua, thiab nws cov khoom siv tau zoo dua li ntawm tungsten. Nws tuaj yeem ua tiav cov txheej txheem ua haujlwm yooj yim xws li CNC milling, tig, thiab drilling, thiab tuaj yeem ua tiav tshuab ntau yam xws li cov xov, cov phab ntsa nyias, thiab cov duab tsis sib xws, xws li molybdenum bolts thiab nyias -cov ntaub thaiv npog cov cua sov.

3. Kev txiav txim siab qhov hnyav thiab qhov ntom ntom -loj- cov khoom siv nplai zoo dua yog siv "tungsten + molybdenum" ua ke.

Rau qhov loj loj -kub qhov cub, siv tungsten raws li ib qho khoom siv hluav taws xob sib hloov yuav ua rau cov khoom hnyav nce ntxiv, tso siab loj rau nws cov load- cov qauv kev coj tus kheej. Qhov no yuav tsis tsuas yog nce nqi tsim khoom tab sis kuj muaj feem cuam tshuam rau kev ua haujlwm ruaj khov thiab kev nyab xeeb.

Kev sib xyaw "tungsten + molybdenum" yog qhov kev xaiv zoo tshaj plaws rau qhov kub siab loj - qhov cub kub. Nws tswj tau qhov hnyav tag nrho ntawm cov khoom siv, txo qhov siab ntawm lub load-cov qauv kabmob, thiab sib npaug tus nqi thiab kev ua haujlwm. Qhov kev sib xyaw ua ke no ua rau muaj txiaj ntsig zoo ntawm ultra- kub zoo ntawm tungsten thiab lub teeb yuag ntawm molybdenum, ua tiav qhov sib npaug zoo ntawm kev ua haujlwm thiab tus nqi.

Rau cov neeg tswj xyuas kev yuav khoom txawv teb chaws, kev xaiv cov khoom siv yuav tsum tsis tsuas yog xav txog kev ua tau zoo, tab sis kuj yog tus nqi thiab rov qab los ntawm peev (ROI).

• Los ntawm qhov kev xav ntawm thawj tus nqi yuav khoom, tungsten yog kim dua li molybdenum. Qhov muag tsis pom kev xaiv tungsten yuav ua rau muaj txiaj ntsig zoo rau kev nqis peev hauv cov khoom siv. Txawm li cas los xij, los ntawm qhov kev xav ntawm qhov ntev - cov nqi khiav lag luam, tungsten muaj qhov zoo dua. Nyob rau hauv ultra- qhov kub thiab txias ib puag ncig, tungsten muaj lub neej ntev kev pab cuam thiab tsawg deformation, uas tuaj yeem txo cov khoom siv poob qis, txo tus nqi txij nkawm, thiab kev poob ntau lawm, ua rau nws pheej yig dua rau lub sijhawm ntev.
• Molybdenum yog tus nqi tshaj plaws - kev xaiv zoo rau cov pa siab - qhov cub kub (xws li lub tshuab nqus tsev vacuum thiab hmoov metallurgy sintering furnaces). Nws tus nqi pib yuav khoom yog nruab nrab, nws tuaj yeem ua tau raws li qhov siab - qhov yuav tsum tau muaj qhov kub thiab txias hauv qab 1800 degree, nws yooj yim rau txheej txheem thiab tswj, thiab nws tsim nyog rau kev yuav khoom ntau thiab siv sijhawm ntev -.

Raws li tus neeg muag khoom tshwj xeeb hauv kev xa tawm tsis yog -ferrous hlau, peb nkag siab tias kev ua raws cai yog qhov tseem ceeb ua ntej rau kev koom tes txawv teb chaws. Txhua batch ntawm tungsten, molybdenum, thiab alloy cov ntaub ntawv uas peb muab yog nrog los ntawm ib tug MTC (Cov ntaub ntawv xeem daim ntawv pov thawj) ua raws li EN 10204 3.1, kom ntseeg tau tias cov khoom vaj tse yog tag nrho raws li kev txiav txim yuav tsum tau thiab ncaj qha raws li kev ua lag luam yuav tsum tau nyob rau hauv lub EU thiab feem ntau lwm cheeb tsam nyob rau hauv lub ntiaj teb no.

Txhawm rau kom ntseeg tau cov khoom zoo, peb tau tsim ib qho kev ua tiav uas tsis yog -kev ntsuas kev puas tsuaj. Txhua batch ntawm cov khoom raug kuaj nruj, suav nrog:

• Kev txheeb xyuas cov tshuaj lom neeg: Siv X-ray fluorescence (XRF) lossis inductively coupled plasma (ICP) thev naus laus zis, peb xyuas kom meej tias qhov purity ntawm tungsten thiab molybdenum cov ntaub ntawv muaj ntau dua lossis sib npaug li 99.95%, tshem tawm cov impurities uas tuaj yeem cuam tshuam cov khoom ua haujlwm siab {2}.
• Vickers/Rockwell Hardness Testing: Ntsuas cov khoom hardness kom ntseeg tau tias cov khoom ua tau raws li kev ua thiab kev siv.
• Ultrasonic Flaw Detection: Sib sib zog nqus soj ntsuam cov khoom sab hauv kom pom cov kab nrib pleb, suav nrog, porosity, thiab lwm yam tsis xws luag, xyuas kom cov khoom tsis muaj qhov tsis zoo.
• Eddy Kev Ntsuas Tam Sim No: Tshawb nrhiav sai sai ntawm qhov chaw thiab nyob ze - qhov chaw tsis xws luag, ua kom cov khoom zoo li qub thiab kev nyab xeeb hauv kev siv, tshwj xeeb tshaj yog tsim rau kev sim cov kav dej, xov hlau, thiab lwm yam khoom zoo sib xws.
