1.Zosakaniza Zosiyana

Nickel chromium alloywaya amapangidwa makamaka ndi faifi tambala (Ni) ndi chromium (Cr), ndipo athanso kukhala ndi zinthu zina zazing'ono. Zomwe zili mu nickel-chromium alloy nthawi zambiri zimakhala pafupifupi 60% -85%, ndipo chromium imakhala pafupifupi 10% -25%. Mwachitsanzo, nickel-chromium alloy Cr20Ni80 ali ndi chromium pafupifupi 20% ndi faifi tambala pafupifupi 80%.

Chigawo chachikulu cha waya wamkuwa ndi mkuwa (Cu), omwe chiyero chake chimatha kufika kupitirira 99,9%, monga T1 mkuwa wangwiro, zamkuwa zomwe zili pamwamba mpaka 99.95%.

2.Zinthu Zosiyanasiyana Zathupi

Mtundu

- Waya wa Nichrome nthawi zambiri amakhala imvi yasiliva. Izi zili choncho chifukwa chitsulo chonyezimira cha nickel ndi chromium chimasakanikirana kuti chipereke mtundu uwu.

- Waya wamtundu wa copper ndi purplish red, womwe ndi mtundu wa copper ndipo umakhala ndi chitsulo chonyezimira.

Kuchulukana

- Kachulukidwe kakang'ono ka nickel-chromium alloy ndi wamkulu, nthawi zambiri pafupifupi 8.4g/cm³. Mwachitsanzo, 1 kiyubiki mita wa waya nichrome ali ndi kulemera pafupifupi 8400 makilogalamu.

-Thewaya wamkuwakachulukidwe ndi pafupifupi 8.96g/cm³, ndipo voliyumu yomweyo ya waya wamkuwa ndiyolemera pang'ono kuposa waya wa nickel-chromium alloy.

Melting Point

-Nickel-chromium alloy imakhala ndi malo osungunuka kwambiri, pafupifupi 1400 ° C, zomwe zimapangitsa kuti zizitha kugwira ntchito pa kutentha kwakukulu popanda kusungunuka mosavuta.

-Kusungunuka kwa mkuwa ndi pafupifupi 1083.4 ℃, yomwe ndi yotsika kuposa ya nickel-chromium alloy.

Mayendedwe Amagetsi

-Waya wamkuwa amayendetsa magetsi bwino, mumkhalidwe wokhazikika, mkuwa umakhala ndi mphamvu yamagetsi pafupifupi 5.96 × 10 kulingalira S/m. Izi ndichifukwa choti mawonekedwe amagetsi a maatomu amkuwa amawalola kuti azichita bwino, ndipo ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'magawo monga kutumiza mphamvu.

Waya wa Nickel-chromium alloy alibe mphamvu yamagetsi, ndipo mphamvu yake yamagetsi ndiyotsika kwambiri kuposa yamkuwa, pafupifupi 1.1×10⁶S/m. Izi ndichifukwa cha kapangidwe ka atomiki ndi kuyanjana kwa faifi tambala ndi chromium mu aloyi, kotero kuti ma elekitironi amalepheretsa pamlingo wina.

Thermal conductivity

-Copper imakhala ndi matenthedwe abwino kwambiri, okhala ndi kutentha kwapakati pa 401W / (m·K), zomwe zimapanga mkuwa wogwiritsidwa ntchito kwambiri m'malo omwe matenthedwe abwino amafunikira, monga zipangizo zopangira kutentha.

Thermal conductivity ya nickel-chromium alloy ndi yofooka, ndipo matenthedwe amatenthedwe nthawi zambiri amakhala pakati pa 11.3 ndi 17.4W/(m·K)

3. Zosiyanasiyana Chemical Properties

Kukaniza kwa Corrosion

Ma aloyi a Nickel-chromium ali ndi kukana kwa dzimbiri, makamaka m'malo otentha kwambiri omwe amakutidwa ndi okosijeni. Nickel ndi chromium zimapanga filimu wandiweyani wa okusayidi pamwamba pa aloyi, kulepheretsa kuwonjezereka kwa okosijeni. Mwachitsanzo, mu mpweya wotentha kwambiri, filimu ya oxide iyi imatha kuteteza zitsulo mkati mwa aloyi kuti zisawonongeke.

- Copper imapangidwa ndi okosijeni mosavuta mumlengalenga kuti ipange mawu (copper carbonate, formula Cu₂(OH)₂CO₃). Makamaka m'malo achinyezi, pamwamba pa mkuwa pang'onopang'ono pamakhala dzimbiri, koma kukana kwake kwa dzimbiri muzinthu zina zopanda oxidizing acid ndikwabwino.

Chemical Kukhazikika

- Nichrome alloy ali ndi kukhazikika kwa mankhwala ndipo amatha kukhala okhazikika pamaso pa mankhwala ambiri. Ali ndi kulolerana kwina kwa zidulo, maziko ndi mankhwala ena, koma amathanso kuchitapo kanthu mu ma oxidizing acids amphamvu.

- Copper muzinthu zina zamphamvu za okosijeni (monga nitric acid) pochita zachiwawa kwambiri, momwe zimachitikira ndi \(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Ntchito Zosiyanasiyana

- nickel-chromium alloy waya

- Chifukwa cha kukana kwake komanso kutentha kwambiri, amagwiritsidwa ntchito makamaka popanga zinthu zotenthetsera zamagetsi, monga mawaya otenthetsera mu uvuni wamagetsi ndi magetsi otenthetsera madzi. Pazida izi, mawaya a nichrome amatha kusintha bwino mphamvu zamagetsi kukhala kutentha.

- Amagwiritsidwanso ntchito nthawi zina pomwe zida zamakina zimafunikira kusungidwa m'malo otentha kwambiri, monga mbali zothandizira ng'anjo zotentha kwambiri.

- Waya wamkuwa

- Waya wamkuwa umagwiritsidwa ntchito makamaka potumiza mphamvu, chifukwa madulidwe ake abwino amagetsi amatha kuchepetsa kutayika kwa mphamvu zamagetsi panthawi yopatsira. Mu dongosolo la gridi yamagetsi, mawaya ambiri amkuwa amagwiritsidwa ntchito popanga mawaya ndi zingwe.

- Amagwiritsidwanso ntchito popanga kulumikizana kwa zida zamagetsi. Muzinthu zamagetsi monga makompyuta ndi mafoni a m'manja, mawaya amkuwa amatha kuzindikira kutumiza kwa chizindikiro ndi magetsi pakati pa zipangizo zosiyanasiyana zamagetsi.
