Fecral alloyFool / strip conpil 0.05mm dhumuc u dhumuc hooyooyinka malabku
Qeybta aluminium-ka sare, oo ay weheliso chromium-ka sare waxay keenaysaa heerkulka sare ee kor u kaca ilaa 1425 c (2600f); Hoos imaatinka kululaynta ee cinwaanka, kuwanFecral alloyS waxaa la barbar dhigaa iyadoo si caadi ah loo isticmaalo FE iyo NI ee saldhigga saldhigga. Sida laga arki karo miiskaas,Fecral alloys Hayso guryo sare marka la barbar dhigo aloys kale ee deegaannada badankood.
Waa in la ogaadaa in, inta lagu gudajiro xaaladaha heerkulka, waxaa ku eg youttrium-ka kaas oo sidoo kale loo yaqaan 'FECRALLOOYS' oo sidoo kale la wanaajinayo adkeynta oxidda, oo ka dhigaya nolosha adeegga ee qaybo ka mid ah fasalka A-1.
Xarafyada 'Fre-Cr-cr-al al alled' waxay ka samaysan yihiin xeryaha saldhiga birta ee 'birta' ee ay ka kooban yihiin waxyaabo yar oo falcelinta ah sida ytrium iyo zrattonium, oo lagu rujin karo, saqaf, daaweynta dusha sare, Imtixaanka kontaroolada iska caabbinta, iwm.
Fe-cr-al-cr-al-cr-al-ka waxaa loo qaabeeyey mashiinka qaboojiyaha si otomaatig ah oo xawaare sare oo awooda awoodda ay gacanta ku hayaan kombiyuutarka, waxaa loo heli karaa silig iyo xargaha (xarig).
Tilmaamaha iyo Faa'iidooyinka
1. Isticmaalka heerkulka, ugu badan ee la isticmaalo heerkulka wuxuu gaari karaa 1400C (0cr21NB, 0cr27a17A17mo2, iwm.)
2. Heerkulka heerkulka hooseeya ee caabbinta
3. Isku-darka kuleylka kuleylka kuleylka kuleylka ee ka hooseeya kan-saldhigga super-ka
4. Koronto koronto oo sareysa
5. Iska ilaaliso hufnaan wanaagsan oo heerkulka sare ah, gaar ahaan jawiga ka hooseeya suldides
6. Load dusha sare
7. Cury-adkeysi
8. Qiimaha hoose ee shaqada, cufnaanta hoose, cufnaanta hoose iyo qiimaha jaban marka la barbar dhigo silig Nichrome.
9. Cadaadiska ka sareeya ee ka sarreeya ee 800-1300ºC
10. Nolosha adeegga dheer
Samaynta wejiyada alumina-ka-qarixi karo alumina sababtuna tahay oksidation of ganacsigaFecral alloyWicooyin (0.5 mm dhumucdiisu) heerkulka kala duwan iyo wakhtiyada waqtiga ayaa la baaray. Muunado ayaa lagu dhajiyay hawo-mareen hawo hawo ah iyadoo la adeegsanayo falanqeeye heerkul ah (TGA). Maskaxda ee muunadaha loo yaqaan 'oxide-ka' waxaa lagu falanqeeyey iyadoo la adeegsanayo skaanka iskaanka elektronikada ah (ESEM) iyo raajada dusha sare ee falanqaynta dusha sare lagu sameeyay iyadoo la adeegsanayo falanqaynta tamarta-raajada (Edx) falanqaynta. Farsamaynta 'raajada' kala-duwanaanta raajada (XRD) waxaa loo isticmaalay in lagu garto marxaladda koritaanka oxide. Daraasadda oo dhan waxay muujisay inay suurta gal tahay in la beero bedka dusha sare ee gamma aluminaFecral alloyMeelaha quduuska ah marka kor lagu dhajiyo kor-ka-saaridda sare ee ka sarreeya 800 ° C ka badan dhawr saacadood.
