Ubuchwepheshe Bokukhiqiza be-Nickel Foam Metal
Igwebu le-nickel, eyaziwa nangokuthi insimbi yesiponji, iyinto yenethiwekhi enezimbobo ezintathu eyakhiwe yi-nickel yensimbi. Ibonakala ngokuhambisa kukagesi okuphezulu, izakhiwo ezilula, isakhiwo esifanayo, ukumelana nokugqwala okuhle kakhulu, kanye nezimbobo eziphezulu, i-nickel Igwebu ithola izinhlelo zokusebenza eziningi kuma-catalyst, amaseli kaphethiloli, izinto zokuvikela i-electrode, izinto ze-electrode, ezokuthutha, kanye nobunjiniyela bokwakha.
Izindlela zokulungiselela isiponji I-Nickel kufaka phakathi i-immersion plating, i-electroless nickel plating, kanye ne-vacuum nickel plating. I-electroless nickel plating iyindlela eyinhloko yokukhiqiza i-sponge nickel, ngokugeleza kwayo okuyinhloko okuhlanganisa ukulungiswa kwezinto zokusetshenziswa, ukwelashwa okuqhubayo, i-electroplating, i-calcination, ukunciphisa, kanye ne-annealing. I-electroless nickel plating inikeza izinzuzo ezifana nokuvuthwa okuphezulu kobuchwepheshe, ukulula kokusebenza, kanye nezidingo zemishini ezilula.Igwebu le-nickel okukhiqizwa ngale ndlela kubonisa izici ezifana nokufana okuhle kakhulu kwembobo kanye nokumelana nokugqwala okuphezulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, imboni ye-nickel foam ikulungele ukukhula okusheshayo.
I-nickel ye-foam ngokuvamile iqukethe i-nickel yensimbi kanye nama-dopants, kanti i-nickel yensimbi ibiza cishe u-70% wezindleko zokukhiqiza. I-nickel yensimbi inikeza izinzuzo ezifana nokumelana nokushisa okuphezulu, ukuguquguquka okuhle kakhulu, kanye namandla aphezulu okusebenza, okwenza isetshenziswe kabanzi emikhakheni yezimboni.
I-Nickel foam inamandla okusebenzisa kabanzi emikhakheni eminingi. Kumaseli kaphethiloli, isebenza njengezinto zokuguqula ipuleti le-bipolar kanye ne-electrocatalyst yamaseli kaphethiloli e-solid oxide (SOFCs), amaseli kaphethiloli e-proton exchange membrane (PEMFCs), kanye namaseli kaphethiloli e-carbonate ancibilikisiwe (MCFCs). Ngaphakathi kwezinto ze-electrode, i-nickel foam isebenza njengezinto ze-electrode zamabhethri kumadivayisi kagesi, njengezingcingo eziphathwayo namathebulethi. Izuza ekudingweni kwemakethe okuqinile, igwebu le-nickel imboni iyaqhubeka nokwandisa amandla ayo entuthuko.
