Abstract: The hollow metal spheres represent the interesting substance, suitable for the cellular material
production by the powder metallurgical method. Thick-walled and thus stronger hollow particles are
of interest for less extremely light-weight but mechanically stronger components. The basic material
properties improving by metal coating deposition is described. The electrolytical and electroless
coating of iron hollow spheres with Cu and Ni, in fluidized bed arrangement, is demonstrated here.
The influence of the deposition method and the coating conditions on the mechanical properties,
surface morphology, and coating composition of the covered spheres were investigated. The effect
of current intensity on current efficiency was also studied there.
It was found that the cell structure, surface morphology, composition, and mechanical properties
of prepared samples are strongly affected by the coating method.
