Ama-alloys e-Copper (Cu) kanye ne-copper-nickel (i-nickel yethusi (Cu-Ni) kokubili kuyizinto ezibalulekile, kodwa ukwakheka kwazo okuhlukile nezici zizenza zifanele ukusetshenziswa okuhlukile. Ukuqonda lo mehluko kuyisihluthulelo sokukhetha into efanele yephrojekthi yakho—futhi uma kuziwa ezindaweni ezidinga kakhulu, imikhiqizo yethu ye-Cu-Ni igqama njengokukhetha okuphezulu.
Emgogodleni wayo, ithusi elimsulwa iyinsimbi ethambile, ethambile eyaziwa ngokusebenza kahle kakhulu kagesi kanye ne-thermal. I-ductile kakhulu, okwenza kube lula ukubumba izintambo, amapayipi, namashidi, okuchaza ukusetshenziswa kwayo kabanzi ezintanjeni zikagesi nasezintweni zokushisa. Kodwa-ke, ithusi elimsulwa linemikhawulo ebalulekile: lijwayele ukugqwala ezindaweni ezinokhahlo, ikakhulukazi lapho lichayeke emanzini anosawoti, ama-acids, noma izinto ezingcolisa imboni. Ngokuhamba kwesikhathi, ikhiqiza i-patina eluhlaza okotshani (ungqimba lwe-oxidation), engenza izinto zibe buthaka futhi ifake engozini ukusebenza ezinhlelweni ezifana nokucubungula olwandle noma amakhemikhali.
Ama-alloys e-Cu-Ni, ngokuphambene, hlanganisa ithusi ne-nickel (imvamisa engu-10-30% we-nickel, kanye nenani elincane lensimbi ne-manganese) ukuze ubhekane nalobu buthakathaka. Lokhu kuhlanganisa kuguqula izakhiwo zezinto, kuqalaukumelana nokugqwala okuphezulu. Okuqukethwe kwe-nickel kudala isendlalelo se-oxide esivikelayo esimelana nokugoba, ukubola kwemifantu, nokuguguleka—ngisho namanzi anosawoti, amanzi anosawoti, noma ukungcola kwezimboni. Lokhu kwenza i-Cu-Ni ilungele izinto zasolwandle njengemikhumbi yemikhumbi, izinhlelo ezithatha amanzi olwandle, kanye namapayipi omshini wokuthungatha uwoyela aphesheya kwezilwandle, lapho ithusi elimsulwa lizowohloka ngokushesha.
Amandla emishini enye indawo lapho i-Cu-Ni idlula khona ithusi elihlanzekile. Ngenkathi ithusi elimsulwa liyi-ductile, alinawo amandla aqinile adingekayo ekusetshenzisweni kwengcindezi ephezulu. Ama-alloys e-Cu-Ni, ngenxa yezakhi zawo ze-alloying, anikeza amandla aphakeme nobulukhuni, okuwenza afanelekele izingxenye zomsebenzi osindayo njengamaphampu, amavalvu, namashubhu okushintsha ukushisa. Futhi agcina ukuguquguquka, okuvumela ukwenziwa lula ngaphandle kokudela ukuqina.
Ngokuphathelene ne-thermal conductivity kanye nogesi, ithusi elihlanzekile lisahola, kodwa i-Cu-Ni igcina ukuhanjiswa okwanele kwezidingo eziningi zezimboni-ngenkathi yengeza inzuzo ebalulekile yokumelana nokugqwala. Le bhalansi yenza i-Cu-Ni ibe yinto ekhethwayo ezindaweni lapho kokubili ukusebenza nokuphila isikhathi eside kubalulekile.
Imikhiqizo yethu ye-Cu-Ni yenzelwe ukusebenzisa lezi zinzuzo. Itholakala ngezinhlobo ezahlukene (izintambo, amashidi, amashubhu) kanye nezingoma ze-nickel, zenziwa ngokunemba ukuze zihlangabezane nezindinganiso eziqinile zomkhakha. Noma ngabe okobunjiniyela basolwandle, ukucutshungulwa kwamakhemikhali, noma imishini yezimboni, imikhiqizo yethu ye-Cu-Ni iletha ukuthembeka, ukuphila isikhathi eside, kanye nokusebenza kahle kwezindleko ithusi elimsulwa elingenakufana nalo. Khetha i-Cu-Ni yezinhlelo zokusebenza lapho ukusebenza ngaphansi kwezimo ezinzima kungaxoxiswana khona—futhi uthembe ukuthi imikhiqizo yethu izodlula okulindele.
