Dab tsi ib puag ncig yog GH2132 tsis haum rau?
GH2132 yog Fe-25Ni-15Cr-based high-temperature alloy uas muaj cov ntsiab lus xws li molybdenum, titanium, aluminium, vanadium thiab cov lej ntawm boron rau kev ntxiv dag zog. Cov hlau no muaj lub zog muaj zog thiab ua haujlwm ntev thiab muaj zog nkag hauv qab 650 degree, thaum tuav cov txheej txheem zoo plasticity thiab txaus siab vuam kev ua tau zoo. Yog li ntawd, nws yog qhov tsim nyog rau kev tsim cov khoom siv hluav taws xob uas muaj qhov kub thiab txias ntawm aeroengines uas ua haujlwm qis dua 650 degree ntev, xws li turbine disks, compressor disks, rotor hniav thiab fasteners.
Txawm li cas los xij, thaum qhov kub thiab txias tshaj 650 degree, cov khoom siv kho tshuab ntawm GH2132 yuav raug txo, cuam tshuam rau nws lub neej kev pab thiab kev nyab xeeb. Tsis tas li ntawd, txawm hais tias GH2132 muaj kev tiv thaiv corrosion zoo, nws yuav tsis tuaj yeem lav qhov kev tiv thaiv corrosion zoo ib yam li lwm cov khoom tshwj xeeb kub-kub alloys nyob rau hauv ib puag ncig kub-kub corrosion. Piv txwv li, piv nrog npib tsib xee-raws li alloys xws li GH4169 uas yog tsim tshwj xeeb rau siv nyob rau hauv huab cua kub ib puag ncig, GH2132 tej zaum yuav tsis muaj raws li kev ua tau zoo raws li yav tas los nyob rau hauv ib tug kub ntawm ntau tshaj 650 degree.
Hauv cov ntsiab lus, GH2132 tsis haum rau kev siv mus sij hawm ntev hauv qhov chaw kub siab tshaj 650 degree, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas xav tau cov cuab yeej zoo heev thiab kev tiv thaiv corrosion ntawm qhov kub siab dua. Thaum xaiv cov ntaub ntawv, qhov ntsuas kub thiab lwm yam kev ua haujlwm ntawm daim ntawv thov tiag tiag yuav tsum raug txiav txim siab kom ntseeg tau tias cov khoom siv tau ua tau raws li qhov xav tau ntawm kev siv hauv ib puag ncig tshwj xeeb.
