1. Siv rau thermal ua pwm
Cov aviation thiab aerospace sectors mas siv molybdenum alloys los ua pwm thiab high-temperature forged cav qhov chaw. Nws daim ntawv thov cov ntaub ntawv yog tsuas yog peb alloys: active hlau carbide ntxiv dag zog rau molybdenum, xaiv lub caij ntxiv dag zog rau molybdenum thiab mechanical dispersion ob-theem zog molybdenum. Active hlau carbide reinforced molybdenum alloy muaj qhov kub thiab txias zog thiab siab thermal conductivity, yog li nws yog tsuas yog siv nyob rau hauv thermal ua pwm kev lag luam. Nws yog qhov tseeb vim tias molybdenum lub siab thermal conductivity thiab qis thermal expansion uas nws yog cov khoom ntawm kev xaiv rau thermal shock kuj.
2. Siv rau molten hlau ua
Aluminium casting nroj tsuag siv molybdenum los kov yeej qhov teeb meem ntawm kub tawg hauv lawv cov ntaub ntawv tiav. Ntawd yog, TZM alloy (titanium-zirconium-molybdenum) cores thiab mandrels (rods) feem ntau yog siv rau hauv qhov chaw ntawm cov ntaub ntawv ua tiav uas muaj cua sov tawg, uas tuaj yeem tiv thaiv kub tawg hauv cov ntaub ntawv. Phem. Kev siv cov TZM thiab MHC alloys kuj tuaj yeem txhim kho qhov muaj peev xwm ceev ceev ntawm cov cuab yeej ua haujlwm. Tungsten-molybdenum alloy muaj tib yam corrosion kuj thiab tuaj yeem txo cov nqi ntau lawm. Yog li ntawd, Mo-25%W thiab Mo-30%W cov ntaub ntawv alloy tau raug tsim los uas tsim nyog rau kev nce qib thiab siv rau hauv impellers, twj tso kua mis thiab cov kav dej zinc molten.
3. Siv rau kev kho cua sov
Piston rings tuaj yeem ua thermally txau nrog 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 tuaj yeem yog cov ntshiab molybdenum lossis molybdenum alloy tov hmoov, uas yog ob qho tib si hnav-tiv taus thiab corrosion-resistant, ua rau nws tsim nyog rau daim ntawv thov kev lag luam. Molybdenum alloy. Ntxiv mus, molybdenum hmoov kuj tuaj yeem sib xyaw nrog cov ntsiab lus sib txawv ntawm nickel, chromium, boron thiab silicon hmoov los tsim cov hmoov sib txawv. Txawm li cas los xij, cov tshuaj tsuag hmoov yuav tsum muaj fluidity zoo. Thermal spray hmoov yuav tsum feem ntau yog spherical los yog ze li ntawm spherical tom qab ziab qhuav. puab. Tsis tas li ntawd, molybdenum thiab molybdenum alloy sib xyaw hmoov kuj tuaj yeem siv rau hauv cov ntshav nozzles kom densify pre-alloyed hmoov ntawm cov khoom sib txawv uas tiv taus hnav thiab corrosion.
4. Siv rau kev kho tshuaj
Siv molybdenum ua cov khoom siv electrode hauv iav melting ua kuj tuaj yeem txhim kho kev ua haujlwm ntawm cov tsoos furnaces. Molybdenum yog tsim los ua cov khoom siv rau cov cua kub kub vim nws lub zog kub kub thiab thermal stability. Piv txwv li, molybdenum thiab molybdenum alloys feem ntau yog siv los ua kub isostatic nias (HIP) cov khoom siv, cov khoom cua sov, lub tes tsho thiab cov hlua khi; molybdenum fixtures thiab sintered molybdenum nkoj yog feem ntau siv nyob rau hauv ceramics; molybdenum yuav luag txhua zaus siv hauv kev lag luam hluav taws xob los tsim oxide ceramic khoom. Tus neeg nqa khoom raug rho tawm haujlwm.
