Abstract:Surface coatings are widely used to improve the mechanical and tribological properties of materials. Recently, pulse current electrodeposition technique has attracted significant attention for industrial coatings due to economically superior and higher quality of deposited coatings.
Extensive studies have been reported with significant improvement in mechanical, wear and corrosion properties of electrodeposited nickel based coatings. These studies investigated tribological properties of co-deposited coatings with a variety of incorporated nanoparticles including Al2O3, ZrO2, TiO2, SiC, W, Si3N4, Fe2O3, and CeO2 [1-4]. However the tribological performance of these coatings in rolling contact subject to water-lubricated environment has been left obscure. Earlier investigations have utiliszed pin-on-disc or ball-on-disc sliding tribo test conditions under dry or oil lubricated environments. Therefore in the current study, a modified ball-on-disk assembly with three balls system was deployed to investigate tribological performance of electrodeposited coatings in immersed water lubrication.
