I-Fe-Cr-Al yombane yokufudumeza yombane yinto esetyenziswa ngokuqhelekileyo kwizixhobo zokufudumeza kunye nezixhobo zombane, kunye ne-Fe-Cr-Al yombane yokufudumeza yombane yenye yezinto eziqhelekileyo. Kwizinto ezisebenzayo, ukuqonda ubudlelwane phakathi kokumelana neengcingo zokufudumeza zombane kunye nobushushu kubalulekile ekuyileni nasekulawuleni izixhobo zokufudumeza. Eli nqaku liza kuphonononga ubudlelwane phakathi kokumelana kunye nobushushu be-Fe-Cr-Al iingcingo zokufudumeza zombane, kwaye bafumane ukuqonda okunzulu kwemigaqo yabo kunye nezinto ezichaphazelayo.
Okokuqala, masiqonde iingqikelelo ezisisiseko zokuxhathisa kunye nobushushu. Ukuchasana kubhekiselele kwisithintelo esifunyenweyo xa i-current idlula kwinto, kwaye ubukhulu bayo buxhomekeke kwizinto ezifana nempahla, imilo kunye nobukhulu bento. Yaye iqondo lobushushu ngumlinganiselo weqondo lokushukuma kwe<em>thermal yeemolekyuli neeathom ezingaphakathi entweni, ngokuqhelekileyo zilinganiswa ngee<em>degree Celsius okanye iKelvin. Kwiintambo zokufudumala zombane, kukho ubudlelwane obusondeleyo phakathi kokumelana nokushisa.
Ubudlelwane phakathi kokuchasana kwe-Fe-Cr-Al iingcingo zokufudumeza zombane kunye nobushushu bunokuchazwa ngumthetho olula wenyama, okuyi-coefficient yokushisa. I-coefficient yeqondo lokushisa libhekiselele ekutshintsheni kokuchasana kwezinto kunye nobushushu. Ngokuqhelekileyo, njengoko ukushisa kukhula, ukuchasana kuyanda. Oku kungenxa yokuba ukunyuka kweqondo lokushisa kunokunyusa ukunyakaza kwe-thermal yee-athomu kunye neeathomu ngaphakathi kwento, ebangela ukungqubana okungaphezulu kunye nemiqobo ekuhambeni kwee-electron kwizinto eziphathekayo, okubangelwa ukwanda kokumelana.
Nangona kunjalo, ubudlelwane phakathi kokumelana neengcingo zokufudumeza ze-iron chromium aluminiyam kunye nobushushu abukho ubudlelwane obulula bomgca. Iphenjelelwa yizinto ezahlukeneyo, phakathi kwazo ezona zibaluleke kakhulu yi-coefficient yokushisa kunye neempawu zezinto eziphathekayo. I-Fe-Cr-Al yombane yokufudumeza intambo ine-coefficient ephantsi yokushisa, oku kuthetha ukuba ukuchasana kwayo kutshintsha kancinane kuluhlu oluthile lokutshintsha kweqondo lokushisa. Oku kwenza i-Fe-Cr-Al yombane yokufudumeza yombane ibe yinto yokufudumala ezinzileyo kwaye ethembekileyo.
Ukongeza, ubudlelwane phakathi kokumelana kunye nobushushu bentsimbi ye-chromium aluminiyam yokufudumeza iphinda iphenjelelwe bubungakanani kunye nokumila kweengcingo zokufudumeza.

Ngokuqhelekileyo, ukuchasana kuhambelana nobude bocingo kunye nokulinganisa ngokungafaniyo nommandla onqamlekileyo. Ke ngoko, iingcingo zokufudumeza ezinde zinokuxhathisa okuphezulu, ngelixa iingcingo zokufudumeza ezityebileyo zinokuxhathisa okuphantsi. Oku kungenxa yokuba iingcingo zokufudumeza ezinde zonyusa indlela yokumelana, ngelixa iingcingo zokufudumeza ezityebileyo zibonelela ngomjelo obanzi wokuhamba.
Kwizicelo ezisebenzayo, ukuqonda ubudlelwane phakathi kokumelana kunye nobushushu beengcingo zokufudumeza zombane ze-Fe-Cr-Al kubalulekile kulawulo olufanelekileyo kunye nohlengahlengiso lwezixhobo zokufudumeza. Ngokulinganisa ukuchasana kocingo lokufudumeza kombane kunye nobushushu be-ambient, sinokufumanisa iqondo lokushisa apho intambo yokufudumala yombane ikhona. Oku kunokusinceda ukulawula kakuhle ubushushu bezixhobo zokufudumeza nokuqinisekisa ukusebenza kwayo okuqhelekileyo kunye nokusetyenziswa ngokukhuselekileyo.
Isishwankathelo, kukho ubudlelwane obuthile phakathi kokumelana neengcingo ze-iron chromium aluminiyam kunye nobushushu. Njengoko iqondo lokushisa linyuka, ukuchasana kuyanda, kodwa utshintsho luncinci ngaphakathi kwinqanaba elincinci. I-coefficient yeqondo lokushisa, iipropati zezinto eziphathekayo, kunye nobukhulu kunye nokumila kocingo lokufudumeza konke kuchaphazela olu budlelwane. Ukuqonda olu budlelwane kunokusinceda siyile ngcono kwaye silawule izixhobo zokufudumeza, siphucule ukusebenza kakuhle kunye nokuthembeka.
