Sekoahelo sa Nichrome sa Boleng bo Holimo sa 80/20 bakeng sa Indasteri ea Lisebelisoa tsa Motlakase

Tlhaloso e Khutšoanyane:

Terata ea Nichrome ea 80/20 ke motsoako o sa keneng makenete o nang le ntlha e phahameng ea ho qhibiliha le ho hanyetsa mafome. Ka lebaka la ho sebetsa hantle ha eona le matla a mocheso o phahameng, e sebelisoa haholo bakeng sa lits'ebetso tse boima indastering ea lisebelisoa tsa motlakase.

Li-alloy tsa nickel Chrome (NiCr) ke thepa e hanyetsang haholo e atisang ho sebelisoa lits'ebetsong tse nang le mocheso o phahameng ka ho fetisisa oa ts'ebetso ho fihlela ho 1,250°C (2,280°F).

Li-alloy tsena tsa Austenitic li tsebahala ka matla a tsona a phahameng a mechini mochesong ha li bapisoa le li-alloy tsa FeCrAl hammoho le matla a tsona a holimo a ho qhaqha. Li-alloy tsa nickel Chrome le tsona li lula li le bonolo ha li bapisoa le li-alloy tsa FeCrAl kamora nako e telele mochesong. Chromium Oxide e lefifi (Cr2O3) e thehoa mochesong o phahameng o ka angoang ke ho phatloha, kapa ho phatloha, e leng se bakang tšilafalo e ka bang teng ho latela ts'ebeliso. oxide ena ha e na thepa ea ho thibela motlakase joalo ka Aluminium Oxide (Al2O3) ea li-alloy tsa FeCrAl. Li-alloy tsa nickel Chrome li bontša khanyetso e ntle ea mafome ntle le libakeng tseo sebabole se leng teng.
