Koranu FeCrAlKonumohe/Rīpene Koiri Matotoru 0.05mm mō ngā Papa Honikoma Whakarewa

Ko te nui o te konumohe, me te nui hoki o te chromium, ka piki ake te pāmahana tauine ki te 1425 C (2600F); I raro i te upoko ātete wera, ko ēneikoranu FeCrAlka whakaritea ki ngā koranu turanga Fe me Ni e whakamahia whānuitia ana. E kitea ana i taua ripanga, ko tekoranu FeCrAlHe pai ake ngā āhuatanga o ēnei konukōre i ērā atu konukōre i te nuinga o ngā taiao.

Me mārama, i ngā āhuatanga pāmahana rerekē, ko te tāpiritanga o te yttrium ki te koranu AF, e mōhiotia ana ko ngā koranu Fecralloys, ka whakapai ake i te piri o te waikura tiaki, ka roa ake te ora mahi o ngā wāhanga o te koranu AF i tērā o te karaehe A-1.

Ko ngā waea koranu Fe-Cr-Al he mea hanga ki ngā koranu turanga konumohe rino-chromium kei roto he iti noa ngā huānga tauhohe pēnei i te yttrium me te zirconium, ā, ka puta mai mā te whakarewa, te hurihuri maitai, te hanga, te whakamahana, te tuhi, te maimoatanga mata, te whakamātautau whakahaere ātete, me ētahi atu.
I hangaia te waea Fe-Cr-Al mā te mīhini whakamatao aunoa tere-teitei, ā, ko te kaha o te mana e whakahaerehia ana e te rorohiko, e wātea ana hei waea me te rīpene (rīpene).

Ngā āhuatanga me ngā painga
1. Te pāmahana teitei e whakamahia ana, ka taea e te pāmahana mōrahi te eke ki te 1400C (0Cr21A16Nb, 0Cr27A17Mo2, me ētahi atu)
2. Te tauwehenga ātete pāmahana iti
3. He iti ake te tauwehenga whānui wera i ngā konukōre-turanga-Ni.
4. Te ātete hiko teitei
5. He ātete pai ki te waikura i raro i te pāmahana teitei, inā koa i raro i te āhuarangi kei roto ngā whanariki
6. Te kawenga mata teitei
7. Ātete ngokingoki
8. He iti ake te utu mō ngā rauemi mata, he iti ake te mātotoru, ā, he iti ake te utu ina whakaritea ki te waea Nichrome.
9. Ātete waikura pai rawa atu i te 800-1300ºC
10. Te roa o te ora ratonga

Te hanganga o ngā āhua alumina pūmau nā te waikura o ngā mea arumonikoranu FeCrAlKua tirohia ngā waea (0.5 mm te matotoru) i ngā pāmahana me ngā wā rerekē. I whakakōkōhia ngā tauira ki te hau mā te whakamahi i tētahi tātaritanga wera-rahi (TGA). I ​​tātarihia te āhua o ngā tauira kua whakakōkōhia mā te whakamahi i tētahi Karuārai Hiko Matawai Hiko (ESEM) ā, i mahia te tātaritanga hihi-X i runga i te mata mā te whakamahi i tētahi tātaritanga hihi-X Marara Pūngao (EDX). I whakamahia te tikanga o te Whakakōkōhia Hiko-X (XRD) hei whakaahua i te wāhanga o te tipu o te waikura. I whakaatuhia e te rangahau katoa he taea te whakatipu i te gamma alumina horahanga-teitei i runga i te mata.koranu FeCrAlngā mata waea ina whakawaikurahia mā te werawera i runga ake i te 800°C mō ētahi haora.
