Tlhaloso: Ni307-2 ke electrode e thehiloeng ho nickel e nang le sekoahelo se tlase sa sodium sa hydrogen. Sebelisa DCEP (electrode ea hona joale e tobileng e ntle). Kaha weld e na le karolo e itseng ea molybdenum, niobium le likarolo tse ling tsa alloying, tšepe e kentsoeng e na le khanyetso e ntle ea mapetso.

Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa litšepe tse kopantsoeng tsa nickel-chromium-iron (tse kang UNS N08800, UNS N06600), e loketse haholo bakeng sa ho tjheseletsa litšepe tse fapaneng, ho tjheseletsa lera la phetoho le ho tjheseletsa holim'a metsi, 'me e ka boela ea sebelisoa ha mocheso o sebetsang e le 980 ° C, empa e ka hanela oxidation ha mocheso o phahame ho feta 820 ° C. Bong le matla a fokotsehileng.

Tsebiso:

1. Electrode e lokela ho besoa hora e le 'ngoe mochesong o ka bang 300℃ pele ho ts'ebetso ea ho tjheseletsa;

2. Ho bohlokoa ho hlwekisa mafome, oli, metsi le litšila likarolong tsa ho tjheseletsa pele o tjheseletsa. Leka ho sebelisa arc e kgutshwane ho tjheseletsa.
