Popis: After the passage of 0.16 A · h of electricity per 1 g of the charge investigated, the amount of nickel in the powder was 13–14 wt.%. The surfaces of the powder particles, which had retained their original shape and dendritic structure, were covered with fairly even, 5- to 8-μm-thick nickel layers. During nickel plating the powders coarsened as a result of coalescence of separate particles, which was especially pronounced with charges containing large nickel additions (up to 30–50%). Additional comminution of nickel-plated powders increased their fineness. The milling operation virtually restored the original fine particle size of powders containing 13–14% of nickel.
