"Phapang" e ho "sehlopha se akaretsang khahlanong le mofuta o itseng"—Ni80 ke ea lelapa la nichrome empa e na le thepa e ikhethang ka lebaka la ho tsitsisoa ha eona, e leng se etsang hore e lokele maemo a khethehileng a mocheso o phahameng. Ka tlase ke papiso e qaqileng:
| Karolo | Nichrome (Sehlopha se Akaretsang) | Ni80 (Mofuta o Ikhethang oa Nichrome) |
| Tlhaloso | Lelapa la di-alloy tse entsweng haholo-holo ka nickel (50-80%) le chromium (10-30%), tse nang le di-additives tse ikgethang (mohlala, tshepe) | Mofuta oa nichrome oa boleng bo holimo o nang le motsoako o tiileng: 80% nickel + 20% chromium (ha ho na li-additives tse ling) |

1. Sebopeho: Se tsitsitseng khahlanong le se tenyetsehang
Nichrome e le sehlopha e dumella dikarolelano tse fetolwang tsa nickel-chromium ho leka-lekanya ditjeo le tshebetso. Mohlala, Ni60Cr15 (60% Ni, 15% Cr) e eketsa tshepe ho fokotsa ditjeo empa e fokotsa ho hanyetsa mocheso. Ka lehlakoreng le leng, Ni80 e na le karolelano e sa buisaneng ya 80:20 nickel-chromium—karolelano ena e phahameng ya nickel ke ka lebaka leo e fetang mefuta e meng ya nichrome ho hanyetsa oxidation le mamello ya mocheso. Ni80 ya rona e kgomarela ka thata maemo a 80:20, ka ho nepahala ha sebopeho ka hare ho ±0.5% (e lekilweng ka spectroscopy ya ho monya athomo).
2. Tshebetso: E Ikhethileng khahlanong le Morero o Akaretsang
Bakeng sa litlhoko tsa mocheso o phahameng (1000–1200°C), Ni80 ha e bapisoe. E boloka botsitso ba sebopeho ka har'a li-oven tsa indasteri kapa lipheletsong tse chesang tsa khatiso ea 3D, ha nichrome e 'ngoe (mohlala, Ni70Cr30) e ka qala ho oxidiza kapa ho fetoha ka holimo ho 1000°C. Leha ho le joalo, bakeng sa mesebetsi ea mocheso o tlase bohareng (mohlala, hitara ea moriri ea 600°C), ho sebelisa Ni80 ha ho hlokahale—mefuta e theko e tlase ea nichrome e sebetsa hantle. Mohala oa rona oa lihlahisoa o akaretsa Ni80 (bakeng sa maemo a batloang haholo) le nichrome e 'ngoe (bakeng sa litlhoko tse theko e tlaase le tse tlase tsa mocheso).
3. Tšebeliso: E reretsoeng khahlanong le e pharaletseng
Sehlopha se seholo sa Nichrome se sebeletsa litlhoko tse fapaneng tsa mocheso o tlase ho isa bohareng: Ni60Cr15 bakeng sa li-heater tse nyane tsa malapa, Ni70Cr30 bakeng sa li-filament tsa toaster tsa khoebo. Ka lehlakoreng le leng, Ni80 e shebane le lits'ebetso tse nang le maemo a holimo, tse nang le mocheso o phahameng: e matlafatsa lionto tsa indasteri tse chesang (moo ho tšoana ha mocheso ho leng bohlokoa) le litsamaiso tsa ho tlosa leqhoa moeeng (moo ho hanyetsa lipotoloho tse batang haholo/tse chesang ho leng bohlokoa). Ni80 ea rona e netefalitsoe bakeng sa ASTM B162 (litekanyetso tsa sebaka sa lifofane) le ISO 9001, ho netefatsa ts'epo masimong ana a hlokang thuso.
Mokhoa oa ho Khetha Pakeng tsa Bona?
- Kgetha nichrome e akaretsang (mohlala, Ni60Cr15, Ni70Cr30) haeba: O hloka ho futhumatsa mocheso o mahareng (<1000°C) mme o behe pele ho boloka ditjeo ka tsela e atlehileng (mohlala, disebediswa tsa ka tlung, dihitara tse nyane).
- Kgetha Ni80 haeba: O hloka botsitso ba mocheso o phahameng (>1000°C), bophelo bo bolelele ba ts'ebeletso (lihora tse fetang 10,000), kapa o sebetsa liindastering tsa bohlokoa (sebakeng sa lifofane, tlhahiso ea indasteri).
Sehlopha sa rona se fana kalipuisano tsa mahala—re tla o thusa ho bapisa mofuta o nepahetseng wa nichrome (ho kenyeletswa le Ni80) le tshebediso ya hao e ikgethang, ho netefatsa tshebetso e ntle le bokgoni ba ditjeo.
