Ntau molybdenum tau noj txhua xyoo ntau dua li lwm cov hlau refractory.Molybdenum ingots, uas ua los ntawm melting ntawm P / M electrodes, yog extruded, dov rau hauv daim ntawv thiab pas nrig, thiab tom qab kos rau lwm yam zeb khoom duab, xws li hlau thiab tubing.Cov ntaub ntawv no tuaj yeem raug stamped rau hauv cov duab yooj yim.Molybdenum kuj yog machined nrog cov cuab yeej zoo tib yam thiab tuaj yeem ua roj tungsten arc thiab electron beam welded, los yog brazed.Molybdenum muaj qhov zoo tshaj plaws hluav taws xob thiab hluav taws xob ua hluav taws xob thiab lub zog tensile siab.Thermal conductivity yog kwv yees li 50% siab dua li cov hlau, hlau lossis npib tsib xee alloys.Nws thiaj li pom kev siv dav li heatsinks.Nws cov hluav taws xob conductivity yog siab tshaj ntawm tag nrho cov refractory hlau, txog ib feem peb ntawm tooj liab, tab sis siab tshaj npib tsib xee, platinum, los yog mercury.Lub coefficient ntawm thermal expansion ntawm molybdenum plots yuav luag linearly nrog kub nyob rau hauv ntau yam.Cov yam ntxwv no, ua ke yuav ua kom muaj peev xwm ua kom sov, suav nrog nws siv hauv bimetal thermocouples.Cov txheej txheem ntawm doping molybdenum hmoov nrog poov tshuaj aluminosilicate kom tau ib qho tsis-sag microstructure piv rau cov tungsten kuj tau tsim.
Kev siv loj rau molybdenum yog ua tus neeg sawv cev rau cov hlau alloy thiab cov cuab yeej hlau, stainless hlau, thiab npib tsib xee-base lossis cobalt-base super-alloys kom kub lub zog, toughness thiab corrosion kuj.Hauv kev lag luam hluav taws xob thiab hluav taws xob, molybdenum yog siv hauv cathodes, cathode txhawb rau cov khoom siv radar, tam sim no ua rau thorium cathodes, magnetron kawg kaus mom, thiab mandrels rau winding tungsten filaments.Molybdenum yog ib qho tseem ceeb nyob rau hauv kev lag luam missile, qhov uas nws yog siv rau high-temperature structural qhov chaw, xws li nozzles, coj ntug ntawm kev tswj qhov chaw, txhawb nqa vanes, struts, reentry cones, kho-kua hluav taws xob shields, tshav kub dab dej, turbine log, thiab twj tso kua mis. .Molybdenum kuj tseem siv tau rau hauv kev lag luam nuclear, tshuaj, iav, thiab metallizing.Kev pabcuam kub, rau molybdenum alloys hauv kev siv cov qauv arc, yog txwv rau qhov siab tshaj plaws ntawm 1650 ° C (3000 ° F).Ntshiab molybdenum muaj kev tiv thaiv zoo rau hydrochloric acid thiab siv rau cov kev pabcuam acid hauv kev lag luam tshuaj.
Molybdenum Alloy TZM
Lub molybdenum alloy ntawm qhov tseem ceeb tshaj plaws thev naus laus zis yog lub zog siab, kub-kub alloy TZM.Cov khoom siv yog tsim los ntawm P / M lossis cov txheej txheem arc-casting.
TZM muaj qhov kub siab dua recrystallization thiab siab dua lub zog thiab hardness ntawm chav tsev thiab ntawm qhov kub siab tshaj qhov tsis muaj molybdenum.Nws kuj pom zoo ductility txaus.Nws superior mechanical zog arc vim dispersion ntawm complex carbides nyob rau hauv molybdenum matrix.TZM yog qhov zoo rau cov ntawv thov ua haujlwm kub vim nws qhov sib xyaw ua ke ntawm cov kub kub hardness, siab thermal conductivity, thiab thermal expansion rau kub ua hauj lwm steels.
Kev siv loj suav nrog
Tuag inserts rau casting txhuas, magnesium, zinc, thiab hlau.
Rocket nozzles.
Tuag lub cev thiab xuas nrig ntaus rau kub stamping.
Cov cuab yeej siv hlau ua haujlwm (vim muaj kev puas tsuaj siab thiab sib tham tsis kam ntawm TZM).
Thaum tshav kub kub shields rau furnaces, structural yam, thiab cua sov ntsiab.
Nyob rau hauv ib qho kev sim los txhim kho lub siab kub lub zog ntawm P / M TZM alloys, alloys tau tsim nyob rau hauv uas titanium thiab zirconium carbide yog hloov los ntawm hafnium carbide.Alloys ntawm molybdenum thiab rhenium yog ductile ntau dua li ntshiab molybdenum.Ib qho alloy nrog 35% Re tuaj yeem dov ntawm chav tsev kub kom ntau dua 95% txo qhov tuab ua ntej tawg.Vim kev lag luam, molybdenum-rhenium alloys tsis siv dav hauv kev lag luam.Alloys ntawm molybdenum nrog 5 thiab 41% Re yog siv rau thermocouple xov hlau.
