Cov ntaub ntawv dab tsi yog GH5188 tsis haum rau?
GH5188 tsis haum raws li cov khoom siv raw rau qhov chaw uas xav tau qhov kub thiab txias ib puag ncig lossis tsis xav tau lub zog siab thiab kub oxidation tsis kam.
GH5188 yog ib qho kev daws teeb meem muaj zog cobalt-based superalloy. Nws yog cov tshuaj muaj zog ntxiv los ntawm kev ntxiv 14% tungsten, kom nws muaj cov khoom zoo heev. Cov hlau no tseem muaj cov ntsiab lus siab dua ntawm chromium thiab cov kab ntawm lanthanum, muab nws zoo kub-kub oxidation tsis kam. GH5188 alloy muaj cov txheej txheem ua haujlwm zoo xws li kev tsim thiab vuam, thiab tsim nyog rau kev tsim cov tshuab aerospace uas xav tau lub zog siab hauv qab 980 degree thiab oxidation tsis kam qis dua 1100 degree.
Txawm li cas los xij, vim tias GH5188 alloy feem ntau ua kom zoo rau cov ntawv thov kub, nws yuav tsis pom qhov ua tau zoo ib yam hauv qhov chaw kub qis. Tsis tas li ntawd, yog tias daim ntawv thov scenario tsis suav nrog cov kev xav tau rau lub zog kub thiab oxidation tsis kam ntawm cov khoom siv, siv GH5188 tuaj yeem ua rau tus nqi tsis tsim nyog, vim tias cov khoom siv qis dua uas tshwj xeeb rau qhov kub thiab txias tsis tas yuav tsum tau ua haujlwm kub. tuaj yeem xaiv tau.
Feem ntau, thaum xaiv cov ntaub ntawv, cov kev cai tshwj xeeb ntawm daim ntawv thov yuav tsum tau txiav txim siab, suav nrog kev ua haujlwm kub, kev xav tau ntawm kev ua haujlwm, kev siv nyiaj txiag thiab lwm yam. Rau qhov chaw uas tsis tas yuav tsum muaj qhov kub thiab txias thiab oxidation tsis kam, los yog siv nyob rau hauv qhov kub thiab txias ib puag ncig, lwm yam alloys los yog cov ntaub ntawv yuav raug txiav txim siab los xyuas kom meej qhov zoo tshaj plaws sib npaug ntawm kev ua tau zoo thiab tus nqi.
