Molybdenum thiab molybdenum alloys muaj cov thermal conductivity zoo, hluav taws xob conductivity, tsis tshua muaj thermal expansion coefficient, siab kub zog, tsis tshua muaj vapor siab thiab hnav tsis kam. Yog li ntawd, lawv tau dhau los ua cov ntaub ntawv tseem ceeb hauv kev tsim cov khoom siv hluav taws xob thiab hluav taws xob, cov khoom siv hlau ua, iav tsim, kub kub rau cov khoom siv hluav taws xob tsim khoom, kev lag luam aerospace thiab kev tiv thaiv kev lag luam. Peb lub tuam txhab tuaj yeem muab ntau yam molybdenum thiab molybdenum alloy khoom xws li Molybdenum Hafnium Carbon Alloy Bar,High Temperature Sintered Molybdenum NkojthiabIon Implantation Parts hauv Molybdenum Thiab Tungsten. Yog tias tsim nyog, koj tuaj yeem xaj peb cov khoom nrog kev ntseeg siab. Nws cov haujlwm tseem ceeb ntawm kev siv hauv kev lag luam khoom siv yog raws li hauv qab no:
1. Thermal ua pwm
Piv txwv li, nyob rau hauv aerospace teb, molybdenum alloys yog tsuas yog siv nyob rau hauv kev tsim cov pwm rau high-temperature forging engine qhov chaw.
2. Molten hlau ua
Aluminium foundries siv molybdenum los tiv thaiv kub tawg ntawm lawv cov ntaub ntawv ua tiav, uas yog, TZM (titanium-zirconium-molybdenum) alloy cores feem ntau yog siv rau hauv cov ntaub ntawv ua tiav uas muaj qhov kub kub tawg, uas tuaj yeem zam kub tawg ntawm cov ntaub ntawv. Kev siv TZM thiab MHC alloys kuj tuaj yeem txhim kho cov khoom siv ceev ceev ntawm cov khoom siv. Tungsten-molybdenum alloy muaj tib yam corrosion kuj, uas tuaj yeem txo cov nqi tsim khoom. Yog li ntawd, Mo-25 feem pua W thiab Mo-30 feem pua W alloy cov ntaub ntawv tsim nyog rau nrov thiab daim ntawv thov nyob rau hauv impeller twj tso kua mis thiab molten zinc yeeb nkab tshuab tau tsim.
3. Thermal txau txheej txheem
Piston rings tuaj yeem ua thermally txau nrog cov khoom siv molybdenum. Tus txheej txheem yog sib tov molybdenum hmoov nrog ib tug binder uas muaj npib tsib xee (Ni) thiab chromium (Cr), thiab ces tsuag cov sib tov ntawm lub piston los ntawm cov ntshav. Cov txheej yuav ua tau ntshiab molybdenum los yog molybdenum alloy tov hmoov, hnav-resistant, corrosion-resistant, haum rau daim ntaub ntawv. Tsis tas li ntawd, cov hmoov sib xyaw ntawm molybdenum thiab molybdenum alloys kuj tuaj yeem siv rau hauv cov plasma nozzles rau cov hmoov ua ntej-alloyed ntawm cov khoom sib txawv.
4. Kev siv tshuaj kho mob
Kev siv cov molybdenum ua cov khoom siv electrode rau iav melting kuj tuaj yeem txhim kho kev ua haujlwm ntawm cov tsoos kub-kub rauv. Cov khoom siv molybdenum zoo haum rau cov khoom siv kub kub hauv qhov cub vim nws qhov kub thiab txias zog thiab thermal stability. Piv txwv li, molybdenum thiab molybdenum alloys feem ntau yog siv los ua cov khoom siv rau kub isostatic pressing (HIP), cov khoom cua sov, lub tes tsho thiab cov hlua. Ntxiv mus, molybdenum fixtures thiab sintered molybdenum tej nkoj nquam feem ntau yog siv nyob rau hauv ceramics, thiab yuav luag tag nrho cov oxide ceramic khoom tsim nyob rau hauv lub electronics kev lag luam raug rho tawm haujlwm nrog molybdenum nqa.
