Ukuxuba ithusi kunye ne-nickel kudala usapho lwee-alloys ezaziwa ngokuba zii-alloys ze-copper-nickel (Cu-Ni), ezidibanisa iipropati ezilungileyo zeentsimbi zombini ukwenza into eneempawu zokusebenza ezibalaseleyo. Olu manyano luguqula iimpawu zazo zibe yiseti yeenzuzo ezisebenzisanayo, ezenzaIialloy zeCu-Niayibalulekanga kwiindlela ezahlukeneyo zokusebenza kwemizi-mveliso—kwaye iimveliso zethu zeCu-Ni zenzelwe ukwandisa ezi nzuzo.
Kwinqanaba leemolekyuli, i-copper kunye ne-nickel zenza isisombululo esiqinileyo xa zidityanisiwe, oko kuthetha ukuba ii-athomu zeentsimbi zombini zisasazeka ngokulinganayo kuyo yonke into. Oku kufana kubalulekile kwiimpawu zazo eziphuculweyo. I-copper ecocekileyo inamandla okuqhuba kwaye iyakwazi ukunyibilika kodwa ayinakho ukumelana nokugqwala, ngelixa i-nickel iqinile kwaye ayixhathisi ukugqwala kodwa ayihambisi kakhulu. Xa zidibene, zenza izinto ezilinganisela ezi mpawu.
Esinye sezona ziphumo zibalulekileyo zalo mxube kukumelana nokugqwala okuphezulu. Umxholo we-nickel kwii-alloys ze-Cu-Ni wenza umaleko we-oxide oqinileyo nokhuselayo phezu komhlaba, okhusela izinto emanzini anetyuwa, ii-asidi, kunye neekhemikhali zoshishino. Oku kwenza ii-alloys ze-Cu-Ni zilungele iimeko zaselwandle, ezinje ngeenqanawa, imibhobho yamanzi olwandle, kunye namaqonga aselunxwemeni, apho ubhedu olucocekileyo luya kugqwala ngokukhawuleza. Iimveliso zethu ze-Cu-Ni, ezenzelwe ezi ndawo zinzima, ziyamelana nokugqwala, ukugqwala kwemiqolo, kunye nokukhukuliseka, okuqinisekisa ukuqina kwexesha elide.
Amandla oomatshini nawo afumana ukomelezwa kumxube we-copper-nickel. Ii-alloys ze-Cu-Ni zinamandla kwaye zinzima kune-copper ecocekileyo, ngelixa zigcina ukuguquguquka okuhle. Oku kuzivumela ukuba zimelane noxinzelelo oluphezulu loomatshini kwizicelo ezifana neepompo, iivalvu, kunye nezitshintshi zobushushu. Ngokungafaniyo ne-copper ecocekileyo, enokonakala phantsi kwemithwalo enzima, iingcingo zethu ze-Cu-Ni kunye namaphepha zigcina ulungelelwaniso lwesakhiwo nokuba ziphantsi kweemeko ezinzima, nto leyo enciphisa iimfuno zolondolozo.
Ukuqhuba kobushushu kunye nombane kuhlala kumangalisa kwii-alloys zeCu-Ni, nangona ziphantsi kancinci kune-copper ecocekileyo. Oku kuzenza zifaneleke kwii-heat exchangers kunye nezixhobo zombane apho ukumelana nokugqwala kubaluleke kakhulu njengokuqhuba. Umzekelo, kwizityalo zokususa ityuwa, iityhubhu zethu zeCu-Ni zidlulisa ubushushu ngokufanelekileyo ngelixa zixhathisa imiphumo yokugqwala yamanzi anetyuwa.
Iimveliso zethu zeCu-Ni ziyafumaneka kwiintlobo ngeentlobo zezinto ezenziwe ngazo, kunye nomxholo we-nickel oqala kwi-10% ukuya kwi-30%,ilungiselelwe iimfuno ezithile zesicelo. Nokuba ufuna iingcingo ezibhityileyo kwiindawo ezintsonkothileyo okanye amaphepha aqinileyo kwizakhiwo ezinzima, ukwenziwa kwethu ngokuchanekileyo kuqinisekisa umgangatho kunye nokusebenza okuzinzileyo. Ngokusebenzisa iingenelo ezikhethekileyo zokuxuba i-copper-nickel, iimveliso zethu zibonelela ngokuthembeka kunye nexesha elide kwiindawo apho iintsimbi ezicocekileyo zingaphumeleli khona.
