Abstract

Article history: Ni–Mo–ZrO composite coatings were produced by electrodeposition technique from citrate electrolytes Received 29 October 2015 containing dispersed ZrO nanopowder. The influence of deposition parameters i.e. concentration of Received in revised form 26 January 2016 molybdate and ZrO nanoparticles in the electrolyte, bath pH and deposition current density on the Accepted 6 February 2016 composition and surface morphology of the coating has been investigated. The structure, microhardness Available online 9 February 2016 and corrosion properties of Ni–Mo–ZrO composites with different molybdenum and ZrO content have 2 2 been also examined. It was found that ZrO content in the deposit is increased by rising the nanopar- Keywords: −3 ticles concentration in the plating solution up to 20 g dm . An increase in molybdate concentration in Electrodeposition the electrolyte affects negatively the amount of codeposited ZrO nanoparticles. The correlation between Ni–Mo alloy the deposition current efficiency and ZrO content in the composite coating has been also observed. A Composite coating decrease in deposition current efficiency leads to deposition of Ni–Mo–ZrO composite with low nanopar- X-ray diffraction 2 Microhardness ticles content.
