Kev Tsim Khoom Siv Nickel Ua Npuas Ncauj Hlau

Ua npuas ncauj nickel, tseem hu ua daim txhuam cev hlau, yog cov khoom siv peb-seem porous network uas muaj cov hlau nickel. Yam ntxwv los ntawm kev ua hluav taws xob siab, cov khoom sib dua, cov qauv sib xws, kev tiv thaiv corrosion zoo heev, thiab porosity siab, nickel Ua npuas ncauj pom ntau daim ntawv thov hauv cov catalysts, cov roj cell, cov ntaub ntawv tiv thaiv electromagnetic, cov ntaub ntawv electrode, kev thauj mus los, thiab kev tsim kho vaj tse.
Cov txheej txheem npaj rau cov paj rwb Nickel suav nrog kev plating immersion, electroless nickel plating, thiab vacuum nickel plating. Electroless nickel plating yog txoj kev tseem ceeb rau kev tsim cov sponge nickel, nrog nws cov txheej txheem tseem ceeb suav nrog kev npaj cov khoom siv raw, kev kho mob conductive, electroplating, calcination, txo qis, thiab annealing. Electroless nickel plating muaj cov txiaj ntsig xws li kev paub txog kev siv tshuab siab, kev yooj yim ua haujlwm, thiab cov khoom siv yooj yim.Ua npuas ncauj nickel Cov khoom tsim los ntawm txoj kev no qhia txog cov yam ntxwv xws li qhov sib npaug zoo heev thiab kev tiv taus xeb zoo dua. Nrog kev nce qib ntawm thev naus laus zis tas mus li, kev lag luam ua npuas ncauj nickel tau npaj rau kev loj hlob sai.
Feem ntau cov nickel ua npuas ncauj muaj cov nickel hlau thiab cov dopants, nrog rau cov nickel hlau suav txog ze li ntawm 70% ntawm cov nqi tsim khoom. Cov nickel hlau muaj cov txiaj ntsig xws li kev tiv taus kub siab, kev ua kom zoo heev, thiab lub zog kho tshuab zoo dua, ua rau nws siv tau dav hauv kev lag luam.
Cov ua npuas ncauj nickel muaj cov kev siv dav dav thoob plaws ntau qhov chaw. Hauv cov roj cell, nws ua haujlwm ua cov khoom siv hloov kho bipolar plate thiab electrocatalyst rau cov roj cell solid oxide (SOFCs), cov roj cell proton exchange membrane (PEMFCs), thiab cov roj cell molten carbonate (MCFCs). Hauv cov ntaub ntawv electrode, cov ua npuas ncauj nickel ua haujlwm ua cov khoom siv electrode rau cov roj teeb hauv cov khoom siv hluav taws xob, xws li xov tooj ntawm tes thiab ntsiav tshuaj. Tau txais txiaj ntsig los ntawm kev thov ua lag luam muaj zog ntxiv, cov ua npuas ncauj nickel kev lag luam txuas ntxiv nthuav nws lub peev xwm tsim kho.
