Xadhkaha xariiqda 0.05mm Dhumucda FeCrAl silig iska caabin ah

Sharaxaad Gaaban:

Maaddada aluminiumka sare, oo ay weheliso maadada chromium-ka sare waxay sababtaa heerkulka is-dabaynta inuu kordho ilaa 1425 C (2600F); Marka la eego ciwaanka iska caabinta kulaylka, kuwan 'FeCrAl alloys' waxaa la barbardhigayaa alwaaxyada aasaasiga ah ee Fe iyo Ni. Sida laga arki karo miiskaas, FeCrAl alloys waxay leeyihiin sifooyin heer sare ah marka la barbar dhigo alloysyada kale ee degaannada badankooda.

    Maaddada aluminiumka sare, oo ay weheliso maadada chromium-ka sare waxay sababtaa heerkulka is-dabaynta inuu kordho ilaa 1425 C (2600F); Hoosta cinwaanka iska caabinta kulaylka, kuwanFeCrAl alloys waxaa la barbardhigayaa Fee-ga iyo Niyada aasaasiga ah ee sida caadiga ah loo isticmaalo. Sida ka muuqata shaxdaas, theFeCrAl alloys waxay leeyihiin sifooyin heer sare ah marka la barbar dhigo alloysyada kale ee degaannada badankooda.

    Waa in la ogaadaa in, inta lagu jiro xaaladaha heerkulka beddelka ah, yttrium ku darida AF alloy oo sidoo kale loo yaqaan 'Fecralloys alloys', waxay hagaajinaysaa u hoggaansanaanta oksaydhka ilaalinta, taasoo ka dhigaysa nolosha adeegga qaybaha AF alloy ka dheer A-1 darajo

    Fe-Cr-Al fiilooyinku waxay ka samaysan yihiin birta chromium aluminium aluminium alwaax ah oo ay ku jiraan xaddi yar oo walxo falgal ah sida yttrium iyo zirconium oo ay soo saaraan dhalada, duubista birta, foornada, nuugista, sawirida, daaweynta dusha, tijaabada xakamaynta iska caabinta, iwm.
    Fe-Cr-Al silig waxaa loo qaabeeyey iyada oo la adeegsanayo mishiinka qaboojinta xawaaraha sare leh kaas oo awoodda korantadu ay maamusho kumbuyuutarka, waxay diyaar u yihiin silig iyo ribbon (strip).

     

    Tilmaamaha iyo faa'iidooyinka
    1. Heerkul sare oo la isticmaalo, heerkulka ugu badan ee isticmaalka wuxuu gaari karaa 1400C (0Cr21A16Nb, 0Cr27A17Mo2, iwm.)
    2. Heerkulka hooseeya ee iska caabbinta
    3. Xidhiidhka fidinta kulaylka oo ka hooseeya Ni-base super-alloys.
    4. Iska caabin koronto oo sarreeya
    5. Iska caabin wanaagsan oo daxalka hoos yimaada heerkulka sare, gaar ahaan marka loo eego jawiga ay ku jiraan sulfides
    6. Culayska dusha sare leh
    7. U adkaysta gurguurta
    8. Qiimaha hoose ee alaabta ceeriin, Cufnaanta hoose iyo qiimaha ka jaban marka la barbar dhigo siliga Nichrome.
    9. Iska caabbinta oksaydhaynta sare ee 800-1300ºC
    10. Nolol adeeg oo dheer

    Samaynta wejiyada alumina ee metastable sababtoo ah oksaydhka ganacsigaFeCrAl alloyfiilooyin (dhammaan 0.5 mm) heerkul kala duwan iyo xilliyo ayaa la baaray. Tijaabooyinku waxay hawada ku jireen osaydhsilis ahaan iyadoo la isticmaalayo falanqeeye heerkulbeeg (TGA). Qaab-dhismeedka muunadaha oksaydhka ah waxaa lagu falanqeeyay iyadoo la isticmaalayo Mikroskoob Electronik Scanning Electron (ESEM) iyo raajada falanqaynta dusha sare waxaa la sameeyay iyadoo la isticmaalayo falanqeeye Tamarta Dispersive X-Ray (EDX). Farsamada X-Ray Diffraction (XRD) ayaa loo isticmaalay in lagu garto wejiga korriinka oksaydhka. Daraasada oo dhami waxay muujisay in ay suurtogal tahay in lagu koro gamma alumina-sare ee dusha sareFeCrAl alloyoogayaasha siligga marka isothermally oksaydhisku ka sarreeyaan 800°C dhowr saacadood gudahood.
