Paper Title:
Microstructure and Property of Nickel Electroformed Using Rotating Cathode in Hard Particles
  Abstract

Nickel deposits were electroformed by a novel technique, in which the mandrel rotated in hard particles (such as ceramic beads) filling between the electrodes. The microstructure and microhardness of the deposit were studied by means of SEM, XRD analysis in contrast with the traditional method. The effects of current densities on the surface morphology and microhardness of the deposit were also studied. The results showed that the polishing, impacting and disturbing of hard particles during electrodepositing could affect the microstructure and performance of the deposits. The grains were substantially refined, the preferred orientation of (200) face weakened and the microhardness significantly increased. Moreover, the presented technique could use higher current density and produce bright and smooth deposits.
