Raws li ib qho ntawm cov khoom tseem ceeb ntawm cov tub rog dav hlau, kev ua haujlwm ntawm lub cav zoo heev cuam tshuam rau nws qhov zoo, kev ua haujlwm ntawm cov tub rog lub cav yog txiav txim siab los ntawm kev ua haujlwm ntawm cov khoom siv high-temperature alloy. Raws li tus neeg sawv cev ntawm cov khoom siv superalloy,tungsten-raws li alloysyog qhov zais cia rau kev tsim cov tub rog ua haujlwm siab.
Tungstenyog cov khoom siv hlau refractory uas muaj lub siab melting point, siab ceev, siab zog, siab hardness, tsis muaj vapor siab, tsis tshua muaj coefficient ntawm thermal expansion, zoo tshuaj stability, thiab corrosion kuj, yog li nws yog haum rau zus tau tej cov high-qib siab. kub resistant Cheebtsam, xws li combustion chamber, nozzle, qhia, turbine disk, tus Tsov tus tw nozzle ntawm tub rog cav.
Vim tias muaj ntau yam ntawm cov tub rog lub cav ua haujlwm nyob rau hauv qhov kub thiab txias rau lub sijhawm ntev, lawv yuav tsum muaj cov cua kub zoo, tiv thaiv corrosion, thiab cuam tshuam tsis kam, thiaj li ua haujlwm ntev dua thiab txo qhov tshwm sim tsis ua haujlwm. Raws litungstenyuav tsis yaj ntawm qhov kub thiab txias, nws yog ib qho tseem ceeb raw cov ntaub ntawv rau high-temperature-resistant engine qhov chaw.
Txawm li cas los xij, vim lub siab ceev ntawmtungsten hlau(li 2.5 npaug ntawm hlau thiab 5 npaug ntawm titanium), uas yuav ua rau kom lub cev hnyav, ua rau tsis zoo rau lub zog txuag thiab emission txo ntawm lub dav hlau, thaum lub oxidation ntawm ntshiab tungsten ntawm qhov kub thiab txias, uas ua rau lub acceleration ntawm lub aircraft. Kev laus ntawm cov khoom sib xws, tungsten-raws li alloys xws li tungsten-molybdenum alloy thiab tungsten-rhenium alloy feem ntau yog siv los tsim cov khoom ua haujlwm siab dua. Tungsten-based alloy yog cov khoom siv alloy raws li tungsten thiab ntxiv nrog me me ntawm molybdenum, rhenium, thiab lwm yam hlau. Piv nrog cov ntshiab tungsten, nws muaj tsawg ceev thiab zoo thermodynamic zog.
Nws yog ib qho tsim nyog sau cia tias tam sim no, vim tias cov khoom tsim tawm me me ntawm cov hlau tungsten thiab cov ntsiab lus ntawm cov khoom siv ntxhia, feem ntau tungsten ores muaj nyob hauv Suav teb, yog li cov teb chaws sab hnub poob tsis muaj peev txheej tungsten txaus los tsim tungsten alloy Aeroengine Parts ntawm qhov loj. .
