1.Kusakaniza

Nickel chromiamu aloyWaya makamaka ndi wopangidwa ndi nickel (ni) ndi chromium (cr), ndipo amathanso kukhala ndi zinthu zina zochepa. Zomwe zili mu nickel-chromial-cromioy nthawi zambiri zimakhala pafupifupi 60% -85%, ndipo zomwe zili chromium zili pafupifupi 10% -25%. Mwachitsanzo, sickel wamba-cromium almoy CR20ni80 ali ndi chromium yomwe ilipo pafupifupi 20% ndi nickel yomwe ili pafupi 80%.

Gawo lalikulu la waya wamkuwa ndi mkuwa (cu), lomwe kuyera kwake kumatha kupitilira 99,9%, monga T1 zoyera, zamkuwa zokhala ngati 99.95%.

2.Kupewa

Mtundu

- waya wa Nichrome nthawi zambiri umakhala wa siliva. Izi ndichifukwa choti zolaula za nickel ndi chromium zimasakanikirana kuti zipereke mtunduwu.

- Mtundu wa waya wamkuwa umakhala wofiyira, womwe ndi mtundu wamkuwa ndipo umakhala ndi chotupa chachitsulo.

Kukula

- Kuchulukitsa kwa mzere wa nickel-chromial-clomiyal ndi yayikulu, nthawi zambiri kuzungulira 8.4g / cm³. Mwachitsanzo, 1 cubic mita ya nichrome waya amakhala ndi pafupifupi 8400 kg.

- Thewaya wamkuwaKuchulukitsa ndi pafupifupi 8.96g / masentimita, ndipo mtundu womwewo wa waya wamkuwa umakhala wolemera kwambiri kuposa ma nickel-chromium alloy waya.

Malo osungunuka

-Cickel-chromial-cromioy alloy amakhala ndi malo okwanira 1400 ° C, zomwe zimapangitsa kuti zizitha kugwira ntchito mosavuta popanda kusungunuka mosavuta.

-Mutu wosuta ndi pafupifupi 1083.4 ℃, yemwe ndi wotsika kuposa wa nickel-chromium iloy.

Zochita zamagetsi

-Kobweya waya umakhala bwino, muyezo, mkuwa uli ndi mawonekedwe a magetsi a ma 5.96 × 10 akuganiza s / m. Izi ndichifukwa choti ma atomu apamkuwa amkuwa amalola kuti azichita bwino, ndipo ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito kwambiri m'minda monga kufalikira kwamphamvu.

Nickel-chromial Almoy Waw Issociation Issociation, ndipo zamagetsi ake ndi otsika kwambiri kuposa momwe mkuwa, pafupifupi 1.1 × 10⁶s / m. Izi zimachitika chifukwa cha kapangidwe ka atomiki ndi kulumikizana kwa nickel ndi chromium mu chiloro, kotero kuti kuphatikizira ma elekitoni kumalepheretseka pamlingo wina.

Mafuta Omwe Amachita

-Cipiper imakhala ndi mawonekedwe abwino kwambiri owombera, okhala ndi mphamvu za pafupifupi 401W / (M ·), zomwe zimapangitsa zamkuwa zambiri zomwe zimagwiritsidwa ntchito kwambiri m'malo omwe mafuta abwino amagwiritsidwa ntchito, monga zida zotentha kutentha.

Thermal khalidwe la nickel-cromial liloy limafooka, ndipo mawonekedwe a mafuta nthawi zambiri amakhala pakati pa 11.3 ndi 17.4w / (M ·)

3.. Mankhwala osiyanasiyana

Kutsutsa

Ma Chromium-cromial olosi ali ndi kukana kokongola, makamaka mu kutentha kwa oxidar. Nickel ndi Cromiamu amapanga filimu yowala kwa oxide padziko lapansi, kupewa oxidation ena amakumana. Mwachitsanzo, mpweya wotentha kwambiri, wosanjikiza uyu wa kanema wa oxide amatha kuteteza zitsulo mkati mwa chipongwe kuchokera ku chilengedwe china.

- mkuwa umakhala oxidized mu mpweya kuti apange vercas (choyambirira Carbonate, formula cru, (o) ₂co₃). Makamaka pamalo otsetsereka pang'ono, pamtengowo pang'onopang'ono udzaphulika, koma kukana kwake ma acid ena osakhalapo.

Kukhazikika kwa mankhwala

- Nichrome Alloy ali ndi bata kwambiri komanso imatha kukhala yokhazikika pamaso pa mankhwala ambiri. Ili ndi kulolerana kwina kwa asidi, zokumba ndi mankhwala ena, komanso amathanso kuchita zinthu mwamphamvu zotsatsa makilogalamu.

- mkuwa mu oxidants (monga Nitric acid) pansi pazachiwawa kwambiri, equations equation ndi \ (3cu + 8hno + 2no + 2h + 2

4.. Ntchito zosiyanasiyana

- Nickel-Cromium Anoy waya

- Chifukwa cha kusamvana kwake kwakukulu komanso kutentha kwambiri kukana, kumagwiritsidwa ntchito makamaka kupanga magetsi ku mavidiyo, monga kumatenthetsa m'mawere oyenda ma unters magetsi komanso magetsi amadzi. Muzolinga izi, nichrome mawaya amatha kutembenuza mphamvu zamagetsi kukhala kutentha.

- Zimagwiritsidwanso ntchito nthawi zina pomwe katundu wa makina ayenera kusungidwa kutentha kwambiri malo, monga othandizira kutentha kwambiri.

- waya wamkuwa

- Waya wamkuwa amagwiritsidwa ntchito potumiza mphamvu, chifukwa mawonekedwe ake amagetsi amatha kuchepetsa kuchepa kwa mphamvu zamagetsi mukamafalitsa. Mu kachitidwe ka Grad Grid, kuchuluka kwa zingwe zambiri zamkuwa kumagwiritsidwa ntchito kupanga mawaya ndi zingwe.

- Amagwiritsidwanso ntchito popanga maulalo a zinthu zamagetsi. Pazogulitsa zamagetsi monga makompyuta ndi mafoni am'manja, mawaya amkuwa amatha kuzindikira kufalitsa siginelo ndi magetsi pakati pa magawo osiyanasiyana amagetsi.
