abstract = {The mechanism of direct galvanic metallization of
insulating polymer surfaces activated by CoS(beta) particles
is investigated by means of conventional electrochemical
techniques-and surface analysis. The results show that a
necessary step to induce metal electrodeposition is the
electrochemical reduction of CoS(beta) occurring at
potentials E < - 0.25 V It is demonstrated that a direct
galvanic metallization can be carried out only by
electrodeposition of metals and alloys with a plating zone
overlapping the reduction zone of CoS. The electrochemical
reduction of CoS is limited by the solid state transport of
sulphide ions from the bulk to the surface of CoS(beta)
particles. The resulting thin Co film on the particle
surface catalyzes the reduction of the depositing metal
leading to the formation of a primary metal film of 10-40 nm
thickness. This primary film, in turn, acts as a seed layer,
onto which further deposition of a secondary metal layer of
higher conductivity takes place. The formation of the
primary metal film makes it possible to contact neighbouring
CoS particles and hence, further lateral propagation of the
metal layer. Experimental results suggest that the
propagation rate of the metal layer is controlled by the
kinetics of sulphide reduction. (c) 2005 Elsevier B.V. All
