Itekhnoloji yokuvelisa iNickel Foam Metal
Igwebu leNickel, eyaziwa ngokuba yi-sponge metal, sisixhobo senethiwekhi esineembobo ezintathu esenziwe yi-nickel yesinyithi. Iphawulwa kukuqhuba kombane okuphezulu, iipropati ezikhaphukhaphu, ulwakhiwo olufanayo, ukumelana nokugqwala okugqwesileyo, kunye neembobo eziphezulu, i-nickel Igwebu ifumana izicelo ezininzi kwi-catalysts, ii-fuel cells, izinto zokukhusela i-electromagnetic, izinto ze-electrode, ezothutho, kunye nobunjineli bokwakha.
Iindlela zokulungiselela isiponji I-Nickel kuquka i-immersion plating, i-electroless nickel plating, kunye ne-vacuum nickel plating. I-electroless nickel plating yeyona ndlela iphambili yokwenza i-sponge nickel, kunye nokuhamba kwayo okuphambili okuquka ukulungiswa kwezinto eziluhlaza, unyango oluqhubayo, i-electroplating, i-calcination, ukunciphisa, kunye ne-annealing. I-electroless nickel plating inikezela ngeenzuzo ezifana nokuvuthwa okuphezulu kobugcisa, ukusebenziseka lula, kunye neemfuno zezixhobo ezilula.Igwebu leNickel iveliswe ngale ndlela ibonisa iimpawu ezifana nokufana kweembobo kunye nokumelana nokugqwala okuphezulu. Ngokuqhubeka nobuchwepheshe, ishishini le-nickel foam likulungele ukukhula ngokukhawuleza.
I-nickel yefoam idla ngokuba ne-nickel yesinyithi kunye nee-dopants, apho i-nickel yesinyithi ithatha phantse i-70% yeendleko zemveliso. I-nickel yesinyithi inika iingenelo ezinje ngokumelana nobushushu obuphezulu, ukuguguleka okugqwesileyo, kunye namandla aphezulu oomatshini, okwenza ukuba isetyenziswe kakhulu kumacandelo emizi-mveliso.
I-Nickel foam inamandla okusetyenziswa ngokubanzi kumacandelo amaninzi. Kwii-fuel cells, isebenza njengesixhobo sokuguqula i-bipolar plate kunye ne-electrocatalyst kwii-solid oxide fuel cells (SOFCs), ii-proton exchange membrane fuel cells (PEMFCs), kunye nee-metalized carbonate fuel cells (MCFCs). Ngaphakathi kwezinto ze-electrode, i-nickel foam isebenza njengesixhobo se-electrode kwiibhetri kwizixhobo ze-elektroniki, ezifana neefowuni eziphathwayo kunye neetablet. Ixhamla kwimfuno yemarike eqinileyo, igwebu le-nickel imboni iyaqhubeka nokwandisa amandla ayo ophuhliso.
