Dab tsi yog Nickel Hlau siv rau?

Kev tsim cov hlau tsis muaj hlau: Nickel yog ib qho tseem ceeb hauv cov hlau tsis muaj steel, nrog rau cov concentration ntawm 8 mus rau 12% npib tsib xee. Qhov kev sib ntxiv no txhim kho cov hlau tsis muaj zog thiab txhim kho nws lub zog thiab ductility, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv.
Alloys: Nickel yog siv nyob rau hauv ntau yam ntawm alloys, nrog rau cov tooj liab (rau cov npib nyiaj npib thiab marine daim ntaub ntawv) thiab nrog chromium (rau kev ua haujlwm siab). Superalloys, uas feem ntau muaj cov nyiaj npib tsib xee, yog siv hauv kev lag luam aerospace thiab kub kub.
Cov roj teeb: Nickel yog ib qho tseem ceeb hauv cov roj teeb uas siv tau, tshwj xeeb hauv cov roj teeb nickel-hlau hydride (NiMH) thiab cov roj teeb nickel-cadmium (NiCd). Nws yog ib qho tseem ceeb rau kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov roj teeb no.
Electroplating: Nickel plating yog txheej txheem siv los tiv thaiv cov hlau tiv thaiv corrosion thiab hnav, ntxiv rau txhim kho lawv qhov zoo nkauj. Nws muab ib qho nyuaj, polished tiav uas txhim khu lub durability ntawm lub hauv paus hlau.
Catalysts: Nickel yog ua hauj lwm raws li ib tug catalyst nyob rau hauv ib tug xov tooj ntawm cov tshuaj tiv thaiv, nrog rau cov koom nyob rau hauv lub hydrogenation txheej txheem siv nyob rau hauv zus tau tej cov margarine thiab lwm yam khoom noj khoom haus.
Kev lag luam tshuaj siv cov khoom siv nickel, xws li nickel sulfate, hauv kev tsim cov catalysts thiab hauv cov txheej txheem electroplating.
Nyob rau hauv marine daim ntaub ntawv, nickel alloys yog heev resistant rau seawater corrosion, ua rau lawv zoo tagnrho rau marine daim ntaub ntawv, xws li shipbuilding thiab offshore lug.
