Iithegi zeMveliso

I-alloy ye-FeCrAl (i-Iron-Chromium-Aluminium) yi-alloy yokumelana nobushushu obuphezulu eyenziwe ngokuyinhloko yentsimbi, i-chromium, kunye ne-aluminium, kunye neemali ezincinci zezinye izinto ezifana ne-silicon kunye ne-manganese. Ezi alloys zisetyenziswa ngokubanzi kwizicelo ezifuna ukuchasana okuphezulu kwi-oxidation kunye nokuxhathisa ubushushu obugqwesileyo, okwenza ukuba zilungele ukusetyenziswa kwizinto zokufudumeza zombane, iziko lemizi-mveliso, kunye nezicelo ezinobushushu obuphezulu obufana neekhoyili zokufudumeza, izifudumezi ezikhanyayo, kunye ne-thermocouples.

1. Iimpawu eziphambili ze-FeCrAl Alloy:

I-1.I-Resistivity ephezulu: Ii-alloys ze-FeCrAl zine-resistivity ephezulu yombane, eyenza ukuba isebenze ngokufanelekileyo kwizinto zokufudumeza.
I-2.I-Resistance ye-Oxidation egqwesileyo: Umxholo we-aluminium wenza i-stable oxide layer phezu komhlaba, inika ukhuseleko oluqinileyo kwi-oxidation nakwiqondo lokushisa eliphezulu.

I-3.Amandla obushushu obuphezulu: Bagcina amandla abo omatshini kunye nokuzinza kwe-dimensional kumaqondo okushisa aphakamileyo, okwenza ukuba bafanelekele iindawo zokushisa okuphezulu.

I-4.UkuFometha okuLungileyo: Ii-alloys ze-FeCrAl zinokwenziwa lula zibe yiingcingo, iiribhoni, okanye ezinye iimilo ezisetyenziselwa ukufudumeza kombane.

I-5.I-Corrosion Resistance: I-alloy ixhathisa ukubola kwiindawo ezahlukeneyo, yongeza ukuqina kwayo.
