    Iithegi zeMveliso

    I-FeCrAl alloy (Iron-Chromium-Aluminum) yi-alloy yokumelana nobushushu obuphezulu eyenziwe ngokuyintloko yintsimbi, i-chromium, kunye ne-aluminium, kunye nezinye izinto ezincinci ezifana ne-silicon kunye ne-manganese. Ezi alloy zisetyenziswa kakhulu kwizicelo ezifuna ukumelana okuphezulu kwi-oxidation kunye nokumelana okuhle kobushushu, okwenza ukuba zilungele ukusetyenziswa kwizixhobo zokufudumeza ngombane, kwiifenitshala zoshishino, nakwizicelo zobushushu obuphezulu ezifana nee-heating coils, ii-radiant heaters, kunye nee-thermocouples.

    1. Iipropati eziphambili ze-FeCrAl Alloy:

    1.Ukumelana Okuphezulu: Ii-alloys ze-FeCrAl zinokumelana okuphezulu kombane, nto leyo eyenza ukuba zisebenze kakuhle kwizinto zokufudumeza.
    2. Ukumelana ne-Oxidation egqwesileyo: Umxholo we-aluminiyam wenza umaleko we-oxide ozinzileyo phezu komphezulu, obonelela ngokhuseleko oluqinileyo kwi-oxidation nokuba kubushushu obuphezulu.

    3. Amandla Obushushu Ophezulu: Zigcina amandla azo oomatshini kunye nozinzo olulinganayo kumaqondo obushushu aphezulu, nto leyo ezenza zifaneleke kwiindawo ezinobushushu obuphezulu.
    4. Ukwakheka Okulungileyo: Ii-FeCrAl alloys zinokwenziwa ngokulula zibe ziintambo, iiribhoni, okanye ezinye iimilo ezisetyenziselwa ukufudumeza ngombane.
    5. Ukumelana Nokugqwala: I-alloy iyamelana nokugqwala kwiindawo ezahlukeneyo, yongeza ukuqina kwayo.
