the cyclic oxidation resistance at 1000-1200 °C. WEISER et al [11] reported that the replacement of Ni by Co in Ni-9Al-8W-8Cr (at.%) alloy enhanced the oxidation resistance at low temperatures (≤850 °C), but decreased the oxidation rate at 900 °C. ISMAIL et al [12] indicated that an increscent in Co concentration decreased the oxidation performance of Co-Ni base superalloys at 800 ......
; Abstract: The recovery of Ni, Co and Mn from spent battery material is very important to environment protection, utilization of resources and cost reduction of the material. The dissolution rates of Ni, Co and Mn with hydrochloric acid as leachant are all over 95% under the optimal conditions of initial hydrochloric acid of 6 mol/L, particle size......
, Changsha 410083, China) Abstract: The leaching kinetics of cobalt from roasting-dissolving residue (Ni-Co concentrate) of a spent catalyst was investigated. The results indicate that the extraction of cobalt from Ni-Co concentrate with sulfuric acid leaching is determined by particle size, sulfuric acid concentration and reaction temperature, while stirring speed in the range of 400-1200 r/min......
低而受到重视[2-4].单槽法电沉积可以避免双槽法镀液交叉污染的缺点,同时,通过严格控制电源和溶液传质等参数可以精确控制膜层结构,因此,其应用较广泛[2].采用电化学方法制备的金属多层膜样品有:Cu-Ni,Ni-Mo,Co-Ni,Ni-Fe,Cu-Zn,Cu-Co,Fe-Cu,Ni-Zn和Co-NiP等.单槽法是将2种或几种活性不同的金属离子以合适的配比加入同一电解液中,控制沉积电位或电流,使其在..., Mazhe R J, et al.
