Ama-alloy ethusi (Cu) kanye nethusi-nickel (ithusi-nickel (Cu-Ni) womabili ayizinto eziwusizo, kodwa ukwakheka kwawo okuhlukile kanye nezakhiwo zawo kuwenza afanelekele izinhlelo zokusebenza ezahlukene. Ukuqonda lokhu kungafani kubalulekile ekukhetheni izinto ezifanele iphrojekthi yakho—futhi uma kukhulunywa ngezimo ezidinga kakhulu, imikhiqizo yethu ye-Cu-Ni ivelele njengokukhetha okuhle kakhulu.
Embindini wayo, ithusi elimsulwa liyinsimbi ethambile, eguquguqukayo eyaziwa ngokuqhuba kahle kukagesi nokushisa. Lithambile kakhulu, okwenza kube lula ukulibumba libe izintambo, amapayipi, namashidi, okuchaza ukusetshenziswa kwalo kabanzi ezintanjeni zikagesi kanye nemishini yokushintshanisa ukushisa. Kodwa-ke, ithusi elimsulwa linemikhawulo ebalulekile: livame ukugqwala ezindaweni ezinzima, ikakhulukazi uma livezwa emanzini anosawoti, ama-acid, noma ukungcola kwezimboni. Ngokuhamba kwesikhathi, liba ne-patina eluhlaza okotshani (ungqimba lwe-oxidation), olungenza buthaka izinto futhi lube sengozini ekusebenzeni okufana nokucubungula olwandle noma amakhemikhali.
Ama-alloy e-Cu-Ni, ngokuphambene nalokho, hlanganisa ithusi ne-nickel (ngokuvamile i-nickel engu-10-30%, kanye nenani elincane lensimbi ne-manganese) ukuze kulungiswe lobu buthakathaka. Le nhlanganisela iguqula izakhiwo zezinto, kuqala ngokuthiukumelana nokugqwala okuphezulu. Okuqukethwe yi-nickel kudala ungqimba lwe-oxide oluvikelayo olumelana nokugoba, ukugqwala kwemifantu, kanye nokuguguleka—ngisho nasemanzini anosawoti, emanzini anosawoti, noma ukungcola kwezimboni. Lokhu kwenza i-Cu-Ni ifaneleke kakhulu ezingxenyeni zasolwandle njengemikhumbi yemikhumbi, izinhlelo zokungenisa amanzi olwandle, kanye namapayipi okugaya uwoyela olwandle, lapho ithusi elimsulwa lingawohloka khona ngokushesha.
Amandla omshini angenye indawo lapho i-Cu-Ni isebenza kahle kakhulu kunethusi elimsulwa. Nakuba ithusi elimsulwa liyi-ductile, alinawo amandla okudonsa adingekayo ekusetshenzisweni okunengcindezi ephezulu. Ama-alloy e-Cu-Ni, ngenxa yezinto zawo zokuhlanganisa, anikeza amandla aphezulu nokuqina, okwenza afaneleke ezingxenyeni ezisindayo njengamaphampu, ama-valve, namashubhu okushintshanisa ukushisa. Aphinde agcine ukuguquguquka, okuvumela ukwenziwa kalula ngaphandle kokulahlekelwa ukuqina.
Ngokuphathelene nokushisa kanye nokushisa kukagesi, ithusi elimsulwa lisahola, kodwa i-Cu-Ni igcina ukuqina okwanele kwezidingo eziningi zezimboni—ngenkathi inezela inzuzo ebalulekile yokumelana nokugqwala. Lokhu kulinganisela kwenza i-Cu-Ni ibe yinto ekhethwayo ezindaweni lapho kokubili ukusebenza kanye nokuphila isikhathi eside kubalulekile.
Imikhiqizo yethu ye-Cu-Ni yenzelwe ukusizakala ngalezi zinzuzo. Itholakala ngezindlela ezahlukene (izintambo, amashidi, amapayipi) kanye ne-nickel, zikhiqizwa ngokunemba ukuze zihlangabezane nezindinganiso eziqinile zemboni. Kungakhathaliseki ukuthi zezobunjiniyela basolwandle, ukucubungula amakhemikhali, noma imishini yezimboni, imikhiqizo yethu ye-Cu-Ni inikeza ukuthembeka, ukuhlala isikhathi eside, kanye nokusebenza kahle kwezindleko okungenakufaniswa nethusi elihlanzekile. Khetha i-Cu-Ni yezinhlelo zokusebenza lapho ukusebenza ezimweni ezinzima kungaxoxiswana ngakho—futhi wethembe imikhiqizo yethu ukuthi izodlula okulindelwe.
