1. Izithako ezahlukeneyo

I-alloy ye-chromium ye-nickelIntambo yenziwe kakhulu yi-nickel (Ni) kunye ne-chromium (Cr), kwaye isenokuba nezinye izinto ezincinci. Umxholo we-nickel kwi-nickel-chromium alloy ngokubanzi umalunga ne-60%-85%, kwaye umxholo we-chromium umalunga ne-10%-25%. Umzekelo, i-nickel-chromium alloy eqhelekileyo i-Cr20Ni80 inomxholo we-chromium omalunga ne-20% kunye nomxholo we-nickel omalunga ne-80%.

Eyona nto iphambili kwintambo yobhedu yi-copper (Cu), ubumsulwa bayo bunokufikelela ngaphezulu kwe-99.9%, njenge-T1 pure copper, umxholo we-copper ufikelela kwi-99.95%.

2. Iipropati ezahlukeneyo zomzimba

Umbala

- Ucingo lweNichrome ludla ngokuba ngwevu yesilivere. Oku kungenxa yokuba ukukhazimla kwesinyithi kwe-nickel kunye ne-chromium kuxutywe ukunika lo mbala.

- Umbala wentambo yobhedu ubomvu omfusa, umbala oqhelekileyo wobhedu kwaye unokukhanya kwesinyithi.

Uxinano

- Uxinano oluthe ngqo lwe-nickel-chromium alloy lukhulu kakhulu, ngokubanzi lumalunga ne-8.4g/cm³. Umzekelo, i-1 cubic meter yocingo lwe-nichrome inobunzima obumalunga ne-8400 kg.

- Iucingo lobheduuxinano lumalunga ne-8.96g/cm³, kwaye umthamo ofanayo wentambo yobhedu unzima kancinci kunentambo ye-nickel-chromium alloy.

Indawo yokunyibilika

I-alloy ye-Nickel-chromium ineqondo lokunyibilika eliphezulu, malunga ne-1400 ° C, nto leyo eyenza ukuba ikwazi ukusebenza kumaqondo obushushu aphezulu ngaphandle kokunyibilika lula.

-Iqondo lokunyibilika kobhedu limalunga ne-1083.4℃, eliphantsi kunelo le-nickel-chromium alloy.

Ukuqhuba kombane

-Intambo yobhedu iqhuba umbane kakuhle kakhulu, kwimeko eqhelekileyo, ithusi linombane ohambayo omalunga ne-5.96×10 guess S/m. Oku kungenxa yokuba ulwakhiwo lwe-elektroniki lweeathom zobhedu luyivumela ukuba iqhube kakuhle umbane, kwaye sisixhobo esisetyenziswa kakhulu, esisetyenziswa kakhulu kwiindawo ezifana nokudluliselwa kwamandla.

Intambo ye-alloy ye-nickel-chromium ayinakho ukuhanjiswa kombane kakuhle, kwaye ukuhanjiswa kombane kwayo kuphantsi kakhulu kunokobhedu, malunga ne-1.1×10⁶S/m. Oku kungenxa yesakhiwo se-athomu kunye nokusebenzisana kwe-nickel kunye ne-chromium kwi-alloy, kangangokuba ukuhanjiswa kwee-electron kuthintelwa kwinqanaba elithile.

Ukuqhuba kobushushu

-Ubhedu lunolawulo lobushushu oluhle kakhulu, lunolawulo lobushushu olumalunga ne-401W/(m·K), nto leyo eyenza ukuba ubhedu lusetyenziswe kakhulu kwiindawo apho kufuneka khona ulungelelwano lobushushu oluhle, njengezixhobo zokusasaza ubushushu.

Ukuqhuba kobushushu kwe-nickel-chromium alloy kubuthathaka kakhulu, kwaye ukuqhubela kobushushu ngokubanzi kuphakathi kwe-11.3 kunye ne-17.4W/(m·K)

3. Iimpawu ezahlukeneyo zeekhemikhali

Ukumelana nokugqwala

Ii-alloy ze-nickel-chromium zinokumelana okuhle nokugqwala, ingakumbi kwiindawo ezishushu kakhulu. I-nickel kunye ne-chromium zenza ifilimu ye-oxide exineneyo kumphezulu we-alloy, zithintela ukusabela okungaphezulu kwe-oxidation. Umzekelo, emoyeni oshushu kakhulu, olu layer lwefilimu ye-oxide lunokukhusela isinyithi esingaphakathi kwe-alloy ekugqwaleni okungaphezulu.

- I-Copper ifakwa i-oxidized ngokulula emoyeni ukuze yenze i-vercas (i-copper carbonate esisiseko, i-formula Cu₂(OH)₂CO₃). Ingakumbi kwindawo enomswakama, umphezulu we-copper uya kubola kancinci kancinci, kodwa ukumelana kwayo nokubola kwezinye ii-asidi ezingezizo i-oxidizing kulungile.

Uzinzo lweeKhemikhali

- I-Nichrome alloy inamandla aphezulu okumelana neekhemikhali kwaye inokuhlala izinzile xa kukho iikhemikhali ezininzi. Iyakwazi ukunyamezela ii-asidi, iziseko kunye nezinye iikhemikhali, kodwa iyakwazi nokusabela kwii-asidi ezinamandla oxidizing.

- I-Copper kwezinye ii-oxidants ezinamandla (ezifana ne-nitric acid) phantsi kwesenzo se-chemical reaction enamandla ngakumbi, i-reaction equation yi \(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Iindlela ezahlukeneyo zokusetyenziswa

- ucingo lwe-alloy ye-nickel-chromium

- Ngenxa yokumelana kwayo okuphezulu kunye nokumelana nobushushu obuphezulu, isetyenziswa kakhulu ekwenzeni izinto zokufudumeza ngombane, ezifana neengcingo zokufudumeza kwii-oven zombane kunye nezifudumezi zamanzi zombane. Kwezi zixhobo, iingcingo ze-nichrome ziyakwazi ukuguqula amandla ombane abe bubushushu ngokufanelekileyo.

- Ikwasetyenziswa nakwezinye iimeko apho iipropati zoomatshini kufuneka zigcinwe kwiindawo ezinobushushu obuphezulu, njengeendawo ezixhasayo zezithando zobushushu obuphezulu.

- Ucingo lwekopolo

- Ucingo lwekopolo lusetyenziswa kakhulu ekudluliseni umbane, kuba umbane walo ohamba kakuhle unokunciphisa ukulahleka kwamandla ombane ngexesha lokudluliselwa. Kwinkqubo yegridi yombane, inani elikhulu leentambo zekopolo zisetyenziselwa ukwenza iintambo kunye neentambo.

- Ikwasetyenziselwa ukwenza uqhagamshelo lwezinto ze-elektroniki. Kwiimveliso ze-elektroniki ezifana neekhompyutha kunye neefowuni eziphathwayo, iingcingo zobhedu zinokudlulisela isignali kunye nokunikezelwa kombane phakathi kwezinto ezahlukeneyo ze-elektroniki.
