Marka hore, waa fure si loo caddeeyo xiriirkooda:Nichrome(oo ku gaaban nikkel-chromium alloy) waa qayb ballaadhan oo ka samaysan nikkel-chromium-ku-salaysan, halkaNi80waa nooc gaar ah oo nichrome ah oo leh halabuur go'an (80% nikkel, 20% chromium). "Farqiga" wuxuu ku jiraa "qaybta guud vs. kala duwanaansho gaar ah" -Ni80 waxay ka tirsan tahay qoyska nichrome laakiin waxay leedahay sifooyin gaar ah sababtoo ah waxay go'an tahay, taasoo ka dhigaysa mid ku habboon xaaladaha heerkulka sare ee gaarka ah. Hoos waxaa ku yaal isbarbardhig faahfaahsan:
| Dhinac | Nichrome (Qaybta Guud) | Ni80 (Nichrome Kala duwanaansho gaar ah) |
| Qeexid | Qoys ka kooban alloys oo inta badan ka kooban nikkel (50-80%) iyo chromium (10-30%), oo leh waxyaabo lagu daro (tusaale, birta) | Kala duwanaansho nichrome ah oo qaali ah oo leh halabuurka adag: 80% nikkel + 20% chromium (ma jiraan wax lagu daro) |
| Dabacsanaanta curinta | Saamiyada nikkel-chromium kala duwan (tusaale, Ni60Cr15, Ni70Cr30) si loo daboolo baahiyaha kala duwan | Go'an 80:20 saamiga nikkel-chromium (malaha dabacsanaan qaybaha asaasiga ah) |
| Waxqabadka Muhiimka ah | Iska caabin heerkul sare oo dhexdhexaad ah (800-1000 ° C), caabbinta oksaydhka aasaasiga ah, iyo iska caabbinta korantada ee la hagaajin karo | Iska caabin heerkul sare oo heersare ah (ilaa 1200°C), iska caabin oksaydhation oo aad u wanaagsan (Qiimayn hoose oo ah 1000°C+), iyo iska caabin korantada oo degan (1.1-1.2 Ω/mm²) |
| Codsiyada caadiga ah | Xaaladaha kululaynta heerkul-hooseeya (tusaale, tuubooyinka kulaylinta qalabka guriga, kuleyliyeyaasha yaryar, kululeeyayaasha warshadaha ee tamarta yar) | Heer kulka sare, xaaladaha baahida sare (tusaale, gariiradda foornada warshadaha, darafyada kulul ee daabacaha 3D, walxaha hawada ka saaraya barafka) |
| Xaddid | Heerkulka ugu sarreeya ee hoose; Waxqabadku wuxuu ku kala duwan yahay saami gaar ah (qaar kala duwanaansho ah ayaa si degdeg ah u oksaydheeya heerkulka sare) | Qiimaha alaabta ceeriin ee sarreeya; u qalma xaaladaha heerkulka hooseeya (aan kharash-ool ahayn) |
1. Halabuurka: go'an vs. dabacsanaan
Nichrome ka qayb ahaan waxay u ogolaataa saamiga nikel-chromium la hagaajin karo si loo dheelitiro qiimaha iyo waxqabadka. Tusaale ahaan, Ni60Cr15 (60% Ni, 15% Cr) waxay ku darsataa birta si loo yareeyo kharashka laakiin waxay hoos u dhigtaa caabbinta kulaylka. Taas bedelkeeda, Ni80 waxay leedahay saamiga 80:20 nikkel-chromium-ka aan la gorgortami karin - waxa ku jira nikkel-kan sare waa sababta ay uga sarreyso noocyada kale ee nichrome ee caabbinta oksaydhka iyo dulqaadka heerkulka. Our Ni80 si adag ugu hoggaansamaan heerka 80:20, oo leh saxnaanta halabuurka gudaha ± 0.5% (tijaabiyay via spectroscopy nuugista atomiga).
2. Waxqabad: Takhasus leh vs. Ujeedo-guud
Baahida heerkulka sare (1000-1200°C), Ni80 lama mid aha. Waxay ku ilaalisaa xasilloonida qaabdhismeedka weelasha warshadaha ama darafyada 3D daabacadaha kulul, halka nichrome kale (tusaale, Ni70Cr30) laga yaabo inuu bilaabo oxidizing ama qallafsanaan ka sarreeya 1000°C. Si kastaba ha ahaatee, hawlaha heerkulka hoose ee dhexe (tusaale, kuleyliyaha timaha qalajiyaha ee 600°C), isticmaalka Ni80 waa mid aan loo baahnayn — kala duwanaanshaha nichrome ka jaban ayaa si fiican u shaqeeya. Khadka alaabtayadu waxay dabooshaa Ni80 labadaba (ee xaaladaha baahida sare leh) iyo nichrome kale (qiimaha xasaasiga ah, baahiyaha heerkulka hooseeya).
3. Codsiga: Bartilmaameedsan vs. Ballaaran
Qeybta ballaaran ee Nichrome waxay u adeegtaa baahiyaha heerkul hoose ilaa dhexe ee kala duwan: Ni60Cr15 kuleyliyaha guriga yar, Ni70Cr30 ee fiilooyinka rootiga ganacsiga. Ni80, marka la barbardhigo, bartilmaameedyada sare, codsiyada heerkulka sare: waxay awood u yeelataa foornooyinka wax-soo-saarka warshadaha (halkaas oo isku mid ahaanshaha heerkulku uu muhiim u yahay) iyo hababka barafka hawada sare (halkaas oo iska caabinta wareegyada qabow / kulaylka daran ay lagama maarmaan tahay). Our Ni80 waxaa loo shahaado ASTM B162 (heerka hawada) iyo ISO 9001, hubinta isku halaynta in goobahan baahida loo qabo.
Sidee Loo Doortaa Dhexdooda?
- Dooro nichrome guud (tusaale, Ni60Cr15, Ni70Cr30) haddii: aad u baahan tahay kuleyl dhexdhexaad ah (<1000°C) oo aad mudnaanta siiso waxtarka-kharashka (tusaale, qalabka guriga, kuleyliyeyaasha yaryar).
- Dooro Ni80 haddii: Aad u baahan tahay xasillooni heerkul sare ah (> 1000 ° C), nolol adeeg oo dheer (10,000+ saacadood), ama aad ka shaqeyso warshadaha muhiimka ah (aerospace, warshadaha wax soo saarka).
Kooxdayadu waxay bixisaawada tashi bilaash ah-waxaanu kaa caawin doonaa inaad is waafajiso kala duwanaanshaha saxda ah ee nichrome (ay ku jirto Ni80) codsigaaga gaarka ah, anagoo hubinayna waxqabadka ugu fiican iyo hufnaanta qiimaha.
