DOI: 10.1016/s1003-6326(20)65276-1
Abstract: Abstract Nickel-cobalt (Ni-Co) alloy powders were produced galvanostatically by using sulphate electrolytes with various ratios of Ni2+/Co2+ (mole ratios). The morphology, phase structure, chemical composition and magnetic properties were examined by scanning electron microscope (SEM),… read more here.
