Kev xav txog kev yuav khoom
① Kev lees paub tus qauv:Qhia meej meej txog tus qauv siv tau thiab xav tau Daim Ntawv Pov Thawj Kev Xeem Khoom (MTC) uas suav nrog cov tshuaj lom neeg, cov khoom siv kho tshuab, thiab cov ntaub ntawv kho cua sov.
② Kev pom zoo:Qhia meej meej txog qhov xwm txheej-txawm li cas los xij- kho ntxiv rau cov laus lossis kev daws teeb meem- kho- raws li cov khoom thiab kev ua haujlwm sib txawv ntawm cov xeev no.
③ Coating Requirements:Vim tias tsis muaj chromium, ntsuas qhov xav tau ntawm MCrAlY lossis aluminide txheej thaum cov khoom siv nyob rau hauv siab -kub oxidizing atmospheres.
④ Qhov txawv ntawm Inconel 718:Thaum ob qho tib si alloys muaj zog zoo sib xws, cov coefficient ntawm thermal expansion (CTE) ntawm 909 yog kwv yees li ib nrab ntawm 718, ua rau nws zoo tagnrho rau kev tshem tawm - cov khoom rhiab heev; 718 muaj oxidation tsis kam. Lawv feem ntau siv nyob rau hauv tandem (piv txwv li, 909 rau sab hauv qis -expansion nplhaib thiab 718 rau sab nrauv load-cov kabmob / oxidation-cov nplhaib resistant).

Qhov tseem ceeb ntawm Curie qhov kub thiab txias: Hauv qab li ntawm 425 degree, lub alloy muaj ferromagnetism thiab qis heev, tas li coefficient ntawm thermal expansion; saum toj no qhov kub thiab txias, nws hloov mus rau lub xeev paramagnetic, thiab expansion coefficient pib nce. Yog li ntawd, qhov zoo tshaj plaws ua haujlwm kub ntau rau 909 alloy yog qis dua 425 degree.
Qhov sib txawv ntawm Incoloy 909 thiab Inconel 718
Txawm hais tias ob qho tib si yog nag lossis daus- cov khoom hnyav superalloys, lawv qhov kev thov cov xwm txheej tau tawm tsam, ua rau lawv ua "ua tiav" khub hauv kev xaiv cov khoom siv rau aero- cav.
Yog tias 718 tau siv los hloov 909, thaum nws lub zog txaus, nws cov thermal expansion ntau dhau yuav ua rau tsis muaj kev tswj hwm kub - xeev clearances - ua rau txo qis kev ua tau zoo ntawm qhov zoo tshaj plaws, lossis kev siv tshuab ua kom tsis zoo.
Yog tias 909 tau siv los hloov 718, cov hlau yuav ua tsis tiav vim oxidation ceev thaum raug kub siab tshaj 650℃lossis rau oxidizing ib puag ncig.
Yog li ntawd, ob qho tib si nquag siv nyob rau hauv tandem thaum lub sij hawm aero- cav tsim: 909 yog ua hauj lwm rau cov khoom uas yuav tsum tau muaj kev ruaj ntseg (xws li turbine casings thiab foob rings), thaum 718 yog siv rau qhov chaw uas yuav tsum tau muaj zog thiab corrosion kuj (xws li turbine disks, hniav, thiab fasteners).
Yog tias koj xav paub ntau ntxiv ntawm Incoloy 718 bar Tshuag, koj tuaj yeem nyem rau ntawm daim duab txuas los sib piv nws ncaj qha nrog 909 alloy thiab xaiv cov kev xaiv uas haum tshaj plaws.
