Ekukhetheni izinto zezimboni, umbuzo othi “Yikuphi okungcono, i-nickel noma ithusi?” uvame ukubuzwa ngamakhasimende. Kodwa-ke, empeleni, akukho “okungcono” ngokuphelele, “okufaneleke kakhulu” kuphela—i-nickel ihamba phambili ekumelaneni nokugqwala kanye nokumelana nokushisa okuphezulu, kuyilapho ithusi linikeza ugesi osezingeni eliphezulu kanye nokusebenza kahle kwezindleko. Ngayinye idlala ngamandla ayo ezimweni ezahlukene. Kusukela ezimpahleni eziyinhloko, amasimu okusetshenziswa, kanye nokusetshenziswa okusebenzayo, lesi sihloko sizokusiza ukucacisa umqondo wokukhetha phakathi kwe-nickel nethusi, okukuvumela ukuthi uthole ikhambi lezinto ezifanele kakhulu izidingo zakho.
Okokuqala, ithebula elingezansi linikeza ukuqhathanisa okucacile kwezakhiwo ezibalulekile kanye neziqondiso zokuzivumelanisa nezimo phakathii-nickel(ngokusekelwe emikhiqizweni yethu ye-nickel emsulwa, enokuhlanzeka okungu-≥99.95%) kanyeithusi(ithusi elihlanzekile lezimboni, elinokuhlanzeka okungu-≥99.9%):
| Ubukhulu bokuqhathanisa | I-Nickel (Izinto Ezihlanzekile Ze-Nickel) | Ithusi (Ithusi Elihlanzekile Lezimboni) | I-Core Adaptation Logic |
| Ukuqhuba Kagesi | Ukuqhuba: 22.1×10⁶ S/m | Ukuqhuba: 58.5×10⁶ S/m (cishe izikhathi ezingu-2.6 kune-nickel) | Khetha ithusi ezimweni ezijwayelekile zokuhambisa umoya; khetha i-nickel ezimweni zokuhambisa umoya ezidinga kokubili ukumelana nokugqwala/ukumelana nokushisa okuphezulu |
| Ukumelana Nokugqwala | Imelana nama-asidi, ama-alkali, kanye nokugqwala koketshezi lomzimba (ihambisana ne-ISO 10993 standard), ayinakugqwala ngemva kwamahora ayi-1000 okucwiliswa emanzini olwandle | Ithambekele ekungcolisweni nasekubunjweni kwe-patina, ukumelana ne-asidi/i-alkali ebuthakathaka, ifanelekela kuphela izindawo ezomile/ezingcolisayo kancane | Khetha i-nickel ezindaweni ezigqwalisayo (imboni yamakhemikhali, ukunakekelwa kwezokwelapha, ezolwandle); khetha ithusi ezindaweni ezomile nezijwayelekile |
| Ukumelana Nokushisa Okuphezulu | Indawo yokuncibilika: 1455℃, izinga lokushisa lesikhathi eside kufika ku-1200℃ | Indawo yokuncibilika: 1083℃, izinga lokushisa lesikhathi eside ≤300℃ | Khetha i-nickel yezimo zokushisa okuphezulu (imishini yokushisa, i-aerospace); khetha ithusi lezimo zokushisa okuphansi/ukushisa kwegumbi |
| Ubuchwepheshe kanye Nokucutshungulwa | Ukuqina okuhle kokushisa okuphansi (kungagotshwa ku--200℃), kungadonswa ezintanjeni ezincane kakhulu ezingu-0.05mm | Ukuguquguquka okuhle kakhulu, kulula ukukunyathela nokukugoba, izindleko zokucubungula eziphansi | Khetha i-nickel ukuze uthole imininingwane yokushisa okuphansi kakhulu/encane kakhulu; khetha ithusi ukuze uthole izidingo zokwakha eziyinkimbinkimbi/ezingabizi kakhulu |
| Amafomu Omkhiqizo Ojwayelekile | Ucingo lwe-nickel oluhlanzekile, umugqa we-nickel alloy, i-foil ye-nickel | Ucingo lwethusi, ibha yebhasi yethusi, ifoyili yethusi | Qondanisa ifomu lomkhiqizo nezidingo zesimo; sinikeza ngokwezifiso ama-alloy e-nickel/copper-nickel |
Ngokombono wezimo zokusetshenziswa ezingokoqobo, umehluko ekukhetheni phakathi kwalezi ezimbili ucacile nakakhulu:
Emkhakheni wokuqhuba ngogesi, ithusi lithandwa kakhulu ezintanjeni zemishini yasekhaya ezivamile kanye nasezintanjeni ezine-voltage ephansi—lihlangabezana nezidingo eziyisisekelo zokuqhuba ngogesi ngenxa yokuqhuba kwalo okuphezulu kanye nezindleko eziphansi. Kodwa-ke, i-nickel iyimfuneko ezintanjeni zangaphakathi zamadivayisi ezokwelapha (isb., izintambo ze-glucose pen probe) kanye nezintambo zesignali yensimbi yendiza: eyokuqala idinga ukumelana nokugqwala koketshezi lomzimba, kanti eyesibili idinga ukumelana nokushisa okuphansi (ngaphansi kuka--50℃ ezindaweni eziphakeme). Izintambo zethu ze-nickel ezihlanzekile ezenziwe ngokwezifiso ezinokubekezelela okungu-0.002mm ziye zaguqulwa amabhizinisi amaningi ezokwelapha/ezindiza.
Ezimweni ezingamelani nokugqwala, i-nickel (hhayi ithusi) ikhethwa njengezendlalelo zamathangi okugcina amakhemikhali kanye nezixhumi zemishini yasolwandle: ithusi liyagqwala phakathi nenyanga eyodwa emanzini anosawoti noma ezindaweni ezine-asidi, kuyilapho izendlalelo zamathangi okugcina ezenziwe ngamapuleti ethu e-nickel ahlanzekile zingavuzi ngemva kweminyaka emi-3 yokusetshenziswa emabhizinisini amakhemikhali. Kodwa-ke, ithusi linenzuzo esobala kakhulu yokusebenza kahle kwezindleko zokuhlobisa izakhiwo kanye nezixhumi ezijwayelekile ezindaweni ezomile.
Ezisetshenzisweni zokushisa okuphezulu, i-nickel kuphela engasetshenziswa ekufudumaleni kwezinto zomshini wokushisa kanye nezintambo zezinzwa zokukhipha ugesi zezimoto: ithusi liyathamba futhi liguquguquke emazingeni okushisa angaphezu kuka-500℃, kuyilapho izinto zokushisa ezenziwe ngezintambo zethu ze-nickel ezihlanzekile zingasebenza kahle ku-1200℃ kuma-oven ezimboni isikhathi esingaphezu kwamahora angu-5000. Ukuze kufudumale izinga lokushisa legumbi (isb., izifudumezi zamandla aphansi ezintweni zasekhaya), ithusi lingakhethwa ukuze kuncishiswe izindleko.
Okuphawulekayo ukuthi lapho isimo sidinga “ukumelana nokushisa kwethusi + ukumelana nokugqwala kwe-nickel,” imikhiqizo yethu ye-copper-nickel alloy (isb., i-CuNi40) iyisisombululo esihle kakhulu—igcina inzuzo yokushisa kwethusi (ukumelana nokushisa: 15×10⁶ S/m) ngenkathi inokumelana nokugqwala kwe-nickel (ukumelana nokugqwala kwamanzi olwandle okufana nokwe-nickel emsulwa), futhi isetshenziswe kabanzi ezintanjeni zasolwandle kanye nemishini yokususa usawoti emanzini olwandle.
Ngamafuphi, isihluthulelo sokukhetha phakathi kwe-nickel nethusi sisekutheni "kungakhathaliseki ukuthi kuyadingeka ukumelana nokugqwala, ukumelana nokushisa okuphezulu, noma ukumelana nokushisa okuphansi kakhulu": uma lezi zakhiwo zidingeka, i-nickel iyisinqumo esithembeke kakhulu; uma kudingeka kuphela ukuguquguquka okuyisisekelo, izindleko eziphansi, kanye nokucutshungulwa okulula, ithusi lifaneleka kakhulu. Uma usangaqiniseki ngokukhethwa kwezinto, sicela ukhululeke ukuxhumana nathi—singakunikeza amasampula enziwe ngokwezifiso e-nickel, ithusi, kanye ne-copper-nickel alloys zingakapheli amahora angu-72 ngokusekelwe kumapharamitha akho esimo (isb., izinga lokushisa, okuphakathi, izidingo zokuguquguquka),ukukusiza ukuthi uqondanise kahle ikhambi lezinto ezibonakalayo.
