    Iithegi zeMveliso

    Ii-alloy zeNickel Chrome (NiCr) zizinto ezinokumelana okuphezulu ezisetyenziswa rhoqo kwiindawo ezinobushushu obuphezulu bokusebenza ukuya kuthi ga kwi-1,250°C (2,280°F).

    Ezi alloys zaseAustenitic zaziwa ngamandla azo aphezulu oomatshini kumaqondo obushushu xa kuthelekiswa nee-alloys zeFeCrAl kunye namandla azo aphezulu okuqhekeka. Ii-alloys zeNickel Chrome nazo zihlala zithambile xa kuthelekiswa nee-alloys zeFeCrAl emva kwexesha elide kumaqondo obushushu. I-Chromium Oxide emnyama (Cr2O3) yenziwa kumaqondo obushushu aphezulu enokuqhekeka, okanye ukuqhekeka, okubangela ungcoliseko olunokwenzeka kuxhomekeke kwisicelo. Le oxide ayinazo iimpawu zokufakelwa kombane ezifana neAluminium Oxide (Al2O3) yee-alloys zeFeCrAl. Ii-alloys zeNickel Chrome zibonisa ukumelana okuhle kokugqwala ngaphandle kweendawo apho kukho isulfure.
