Ukuxuba ubhedu kunye ne-nickel kudala usapho lwe-alloys eyaziwa ngokuba yi-copper-nickel (Cu-Ni) alloys, edibanisa iipropati ezingcono kakhulu zombini iintsimbi ukwenza izinto ezineempawu zokusebenza ezikhethekileyo. Oku kudityaniswa kuguqula iimpawu zabo zomntu ngamnye zibe yiseti ye-synergistic yeenzuzo, ukwenzaCu-Ni ingxubevangeKubalulekile kwizicelo ezahlukeneyo zemizi-mveliso-kwaye iimveliso zethu ze-Cu-Ni zenzelwe ukukhulisa ezi zibonelelo.
Kwinqanaba lemolekyuli, ubhedu kunye ne-nickel zenza isisombululo esiqinileyo xa sixutywe, oku kuthetha ukuba iiathom zazo zombini isinyithi zisasazwa ngokufanayo kuyo yonke into. Oku kufana ngundoqo kwiimpawu zabo eziphuculweyo. Ubhedu olusulungekileyo lusebenza kakhulu kwaye luyathambile kodwa alukwazi ukumelana nomhlwa, ngelixa i-nickel yomelele kwaye iyamelana nokukhula kodwa ayiqhubeki kangako. Ngokudibeneyo, benza izinto ezilungelelanisa ezi mpawu.
Esinye sezona ziphumo zibalulekileyo zalo mxube kukunganyangeki kwe-corrosion ephezulu. Isiqulatho se-nickel kwi-Cu-Ni alloys senza umaleko oshinyeneyo, okhuselayo weoksidi kumphezulu, ukhusela imathiriyeli kumanzi anetyuwa, iiasidi, kunye neekhemikhali zemizi-mveliso. Oku kwenza i-Cu-Ni alloys ilungele imeko-bume yaselwandle, enje ngeenqanawa, imibhobho yamanzi olwandle, kunye namaqonga angaphandle konxweme, apho ubhedu olusulungekileyo lunokonakala ngokukhawuleza. Iimveliso zethu ze-Cu-Ni, ezilungiselelwe ezi setingi zingqwabalala, zixhathise imingxuma, ukubola kwemingxuma, kunye nokhukuliseko, ziqinisekisa ukuqina kwexesha elide.
Amandla omatshini nawo afumana ukongezwa kumxube wobhedu-nickel. I-Cu-Ni alloys yomelele kwaye inzima kunobhedu olusulungekileyo, ngelixa igcina i-ductility elungileyo. Oku kubavumela ukuba bamelane noxinzelelo oluphezulu lomatshini kwizicelo ezinjengeempompo, iivalvu, kunye nokutshintsha ubushushu. Ngokungafaniyo nobhedu olusulungekileyo, olunokukhubazeka phantsi kwemithwalo enzima, iingcingo zethu ze-Cu-Ni kunye namaphepha zigcina ingqibelelo yesakhiwo nakwiimeko ezinzima, ukunciphisa iimfuno zokugcina.
I-Thermal kunye ne-conductivity yombane ihlala ichukumisa kwi-Cu-Ni alloys, nangona ingaphantsi kancinci kunobhedu olusulungekileyo. Oku kubenza bafanelekele ukutshintshiselana kobushushu kunye namacandelo ombane apho ukuxhathisa kwe-corrosion kubaluleke kakhulu njenge-conductivity. Ngokomzekelo, kwizityalo zokukhupha ityuwa, iityhubhu zethu ze-Cu-Ni zigqithisa ngokufanelekileyo ubushushu ngelixa zixhathisa imiphumo ephazamisayo yamanzi etyuwa.
Iimveliso zethu ze-Cu-Ni zifumaneka kwiingoma ezahlukeneyo, kunye nomxholo we-nickel ukusuka kwi-10% ukuya kwi-30%,ilungiselelwe iimfuno ezithile zesicelo. Nokuba ufuna iingcingo ezicekethekileyo zamalungu antsonkothileyo okanye amashiti ashinyeneyo omsebenzi onzima, ukwenziwa kwethu okuchanekileyo kuqinisekisa umgangatho kunye nokusebenza okungaguqukiyo. Ngokusebenzisa iinzuzo ezizodwa zokuxuba i-copper-nickel, iimveliso zethu zihambisa ukuthembeka kunye nokuphila ixesha elide kwiindawo apho iintsimbi ezicocekileyo zisilela.
