Ni matrix composite electrocoatings containing SiC particles were produced from an additive-free nickel Watts type bath. Electrodeposition of Ni/SiC composites was carried out under both direct and pulse current conditions, in order to study the effect of the electroplating parameters on the hardness and wear resistance of Ni/SiC composite coatings. The mechanical properties of the composite Ni/SiC electrocoatings were shown to depend on the electrolysis parameters, the type of current, the codeposition percentage of particles and the microstructural modification induced by codepositing SiC particles. The experimental data revealed that in comparison with pure nickel, the incorporation of SiC particles in Ni matrix improves significantly the mechanical behaviour of composite coatings.
