Abstract

Nickel coating has a poor surface mechanical properties. In order to improve the mechanical properties, nickel were covered with ceramic particles. In this study, the Ni/TiN composite coatings were produced by Watts bath containing TiN nanoparticles. The effects of deposition current density, electrolyte agitation speed and the number of particles were investigated. The presence of particles was determined by EDS analysis and the coating morphology was examined by SEM. The corrosion samples were examined by linear polarization tests. It was observed that the maximum amount of particles is formed at the current density of 4 A/dm2 and the agitation speed of 450 rpm.
