Njengoko uqoqosho lukhula, kukho imfuno ekhulayo yomgangatho ophezulu, izinto ezihlala ixesha elide kunye neziguquguqukayo kushishino lwanamhlanje. Esinye sezi zixhobo zifunwa kakhulu, i-FeCrAl, i-asethi exabisekileyo kwinkqubo yokuvelisa kunye nemveliso ngenxa yoluhlu olubanzi lweenzuzo ezinokuthi zisetyenziswe kwizicelo ezahlukeneyo.
I-iron chromium aluminiyam, ekwabizwa ngokuba yi (FeCrAl), iqulethe intsimbi, ichromium kunye ne-aluminiyam enexabiso elincinci le-yttrium, i-silicon kunye nezinye izinto. Le ndibaniselwano yezinto inika into ebalaseleyo ukumelana nobushushu, i-oxidation kunye nokubola.
Enye yeenzuzo eziphambili zokuba yiIngxubevange yeFeCrAlkukuxhathisa kwayo kumaqondo obushushu aphezulu. Oku kubenza bafanelekele izinto zokufudumeza, iziko loshishino kunye nezinye izicelo eziphezulu zokushisa. Ikhono le-FeCrAl lokumelana namaqondo obushushu aphezulu ixesha elongeziweyo ngaphandle kokuthotywa okubalulekileyo kwenza kube lolona khetho lukhethiweyo lokufudumeza okubalulekileyo kunye neenkqubo zonyango lobushushu.
Ukongeza ekuchaseni amaqondo obushushu aphezulu, i-FeCrAl ikwanokumelana ne-oxidation ebalaseleyo. Oku kuthetha ukuba bagcina ingqibelelo yesakhiwo kunye nokusebenza naxa bevezwe kubushushu obuphezulu, iindawo ezityebileyo zeoksijini. Ngesi sizathu, i-FeCrAl ihlala isetyenziswa kwizicelo apho ukuxhathisa kwe-oxidation kubaluleke kakhulu, njengokuveliswa kwee-oveni zemizi-mveliso, ii-kilns kunye nezixhobo zokunyanga ubushushu.
Ukongeza, ukumelana nokubola kweFeCrAliyenza ilungele iimeko zemizi-mveliso ezinomngeni. Ukuba ibonakaliswe kwiimeko zokusebenza ezimanzi, zeekhemikhali okanye ezinzima, i-FeCrAl inokumelana nobunzima bemeko yezoshishino, iyenze ibe lukhetho oluthembekileyo kumacandelo kunye nezixhobo ezichatshazelwa zizinto ezinobungozi.
Ukuguquguquka kwe-FeCrAl akuphelelanga kwiimpawu zayo zokumelana nombane. Ezi zixhobo zinokubunjwa ngokulula, zifakwe kwi-welded kunye nomatshini, zivumela ukuguquguquka kwindlela yoyilo kunye neyokuvelisa. Oku kuguquguquka kwenza i-aluminium ye-ferrochromium ibe yimathiriyeli yokuzikhethela ukwenza iimilo ezintsonkothileyo kunye namalungu, inika iinjineli kunye nabayili inkululeko yokuyila izisombululo ezintsha zosetyenziso olwahlukeneyo.
Kwishishini leemoto, i-FeCrAl isetyenziselwa ukuvelisa abaguquli be-catalytic, apho ukumelana nobushushu obuphezulu kunye nokuqina kungundoqo kunyango olusebenzayo lweegesi zokukhupha. Ishishini le-aerospace likwaxhamla ekusebenziseni i-FeCrAl ekwenzeni amacandelo e-injini yeenqwelo-moya, apho isakhono semathiriyeli sokumelana namaqondo obushushu agqithisileyo kunye neemeko zokusebenza ezinzima ngundoqo ekusebenzeni okuthembekileyo.
Ukongeza, imboni yamandla ixhomekeke kwi-iron-chromium-aluminium ukuvelisa izinto zokufudumeza kwizifudumezi zamanzi zombane, iibhoyili zamashishini kunye neziko. Ikhono lezinto eziphathekayo ukubonelela ngokuhambelana kokushisa kunye nokuthembeka kwexesha elide kwenza kube yinxalenye ebalulekileyo yeenkqubo zokufudumeza amandla. Kwi-electronics yabathengi, izinto ze-ferro-chromium-aluminium zisetyenziswa kwizixhobo ezifana ne-toaster, izomisi zeenwele, kunye nee-oveni zombane, apho ukumelana nobushushu obuphezulu kunye nokuqina kungundoqo ekusebenzeni okukhuselekileyo nokuthembekileyo.
Indima ye-FeCrAl iya isibaluleka ngakumbi njengoko ishishini liqhubeka nokukhula kwaye lifuna imathiriyeli ephucukileyo ukuhlangabezana neemfuno zezicelo zalo. Ukuxhathisa okukodwa kwe-FeCrAl Alloy kumaqondo obushushu aphezulu, i-oxidation kunye nokudleka, kudityaniswa nokuguquguquka kwayo kwemveliso, kuyenza ibe yi-asethi yexabiso kusukelo lokuvelisa izinto ezintsha kunye nempumelelo kuluhlu olubanzi lwemizi-mveliso.
Ngamafutshane, ukuguquguquka kweIialloyi zeFeCrAlkwishishini lanamhlanje alithandabuzeki. Ukusuka kwizicelo zobushushu obuphezulu ukuya kwindawo ezonakalisayo, i-FeCrAl alloys ibonelela ngezisombululo ezithembekileyo, ezihlala ixesha elide kwimingeni eyahlukahlukeneyo yeshishini. Njengoko imfuno yezinto eziphezulu zokusebenza ziqhubeka zikhula, indima ye-iron-chromium-aluminium ekubunjweni kwexesha elizayo lokuvelisa kunye neenkqubo zokuvelisa ngokuqinisekileyo ziya kwanda, okwenza kube sisiseko sokusetyenziswa kwamashishini anamhlanje.
