• Description: Plasma activated tungsten carbide and alumina ceramic powders were evaluated for their impact on electrochemical deposition of Cu and Ni metal matrix composite layers on steel substrate. Plasma activation was done by coplanar dielectric barrier discharge, operating in air at atmospheric pressure. In all experiments surface microstructure involving plasma activated powders was altered. More importantly, plasma treatment provided a statistically significant change in hardness of deposited layers. The effect was most pronounced for Cu metal matrix.
