Njengoba umnotho uthuthuka, kunesidingo esikhulayo sekhwalithi ephezulu, izinto ezihlala isikhathi eside futhi eziguquguqukayo embonini yesimanje. Enye yalezi zinto ezifunwa kakhulu, i-FeCrAl, iyimpahla eyigugu enqubweni yokukhiqiza nokukhiqiza ngenxa yobubanzi bayo bezinzuzo ezingasetshenziswa ezinhlelweni ezihlukahlukene.
I-iron chromium aluminium, eyaziwa nangokuthi (i-FeCrAl), iqukethe insimbi, i-chromium ne-aluminium enamanani amancane e-yttrium, i-silicon nezinye izakhi. Le nhlanganisela yezinto inika izinto ukumelana okuhle kakhulu nokushisa, i-oxidation kanye nokugqwala.
Enye yezinzuzo eziyinhloko zokuba iIngxubevange ye-FeCrAlukumelana kwayo namazinga okushisa aphezulu. Lokhu kubenza bafaneleke ukufudumala izakhi, izithando zezimboni nezinye izinhlelo zokusebenza ezishisa kakhulu. Ikhono le-FeCrAl lokumelana nezinga lokushisa eliphezulu isikhathi eside ngaphandle kokuwohloka okukhulu likwenza kube ukukhetha okuncanyelwayo kokushisisa okubalulekile namasistimu okwelapha ukushisa.
Ngaphezu kokumelana kwayo nokushisa okuphezulu, i-FeCrAl futhi inokumelana ne-oxidation okuhle kakhulu. Lokhu kusho ukuthi bagcina ubuqotho besakhiwo nokusebenza ngisho nalapho bevezwe endaweni enezinga lokushisa eliphezulu, enomoya-mpilo. Ngenxa yalesi sizathu, i-FeCrAl ivamise ukusetshenziswa ezinhlelweni lapho ukumelana ne-oxidation kubaluleke kakhulu, njengokukhiqizwa kwamahhavini ezimboni, okokhela kanye nemishini yokwelapha ukushisa.
Ngaphezu kwalokho, ukumelana nokugqwala kweI-FeCrAliyenza ifanelekele izindawo zezimboni eziyinselele. Kungakhathaliseki ukuthi ibhekene nezimo zokusebenza ezimanzi, zamakhemikhali noma ezinzima, i-FeCrAl ingakwazi ukumelana nobunzima bendawo yezimboni, ikwenze kube ukukhetha okuthembekile kwezingxenye nezinto zokusebenza ezithintwa izakhi ezigqwalayo.
Ukuguquguquka kwe-FeCrAl akukhawulelwe ezicini zayo zokumelana nogesi. Lezi zinto zingakhiwa kalula, zishiselwe futhi zenziwe ngomshini, okuvumela ukuguquguquka ekuklanyeni nasekukhiqizeni inqubo. Lokhu kuguquguquka kwenza i-ferrochromium i-aluminium ibe yinto ekhethwayo ekwenzeni izimo eziyinkimbinkimbi nezingxenye, okunikeza onjiniyela nabaklami inkululeko yokudala izixazululo ezintsha zezinhlelo zokusebenza ezihlukahlukene.
Embonini yezimoto, i-FeCrAl isetshenziselwa ukukhiqiza iziguquli ze-catalytic, lapho ukumelana nokushisa kwayo okuphezulu nokuqina kuyisihluthulelo sokwelashwa okusebenzayo kwamagesi akhipha umoya. Imboni ye-aerospace iphinde izuze ekusetshenzisweni kwe-FeCrAl ekwenzeni izingxenye zenjini yendiza, lapho ikhono lempahla lokumelana nezinga lokushisa elidlulele nezimo zokusebenza ezinzima liwukhiye ekusebenzeni okuthembekile.
Ngaphezu kwalokho, imboni yamandla incike ku-iron-chromium-aluminium ukukhiqiza izakhi zokushisa kuma-heaters amanzi kagesi, ama-boilers ezimbonini nasezithandweni. Ikhono lezinto ezibonakalayo lokuhlinzeka ngokukhipha ukushisa okungaguquki nokuthembeka kwesikhathi eside kuyenza ibe yingxenye ebalulekile yamasistimu okushisa awonga amandla. Kuma-electronics abathengi, izinto ze-ferro-chromium-aluminium zisetshenziswa ezintweni ezinjengama-toaster, okomisa izinwele, namahhavini kagesi, lapho ukumelana nokushisa kwawo okuphezulu nokuqina kuyisihluthulelo sokusebenza okuphephile nokuthembekile.
Iqhaza le-FeCrAl liya ngokuya libaluleka njengoba imboni iqhubeka nokukhula futhi idinga izinto ezithuthukisiwe ukuze ihlangabezane nezidingo zezicelo zayo. Ukumelana okuyingqayizivele kwe-FeCrAl Alloy kumazinga okushisa aphezulu, i-oxidation kanye nokugqwala, kuhambisana nokusebenza kwayo ngezindlela ezihlukahlukene, kuyenza ibe yimpahla ebalulekile ekuphishekeleni ukuqamba izinto ezintsha nokusebenza kahle ezinhlobonhlobo zezimboni.
Ngamafuphi, ukuhlukahluka kweAma-alloys e-FeCrAlembonini yesimanje akungabazeki. Kusukela ezinhlelweni zokushisa eziphakeme kuya ezindaweni ezigqwalile, ama-alloys e-FeCrAl ahlinzeka ngezixazululo ezinokwethenjelwa, ezihlala isikhathi eside ezinseleleni ezihlukahlukene zezimboni. Njengoba isidingo sezinto ezisebenza kahle kakhulu siqhubeka sikhula, indima ye-iron-chromium-aluminium ekubumbeni ikusasa lezinqubo zokukhiqiza nokukhiqiza ngokuqinisekile izokhula, iyenze ibe yitshe lesisekelo lezicelo zezimboni zesimanje.
