Abstract: A new composite coating, nickel-quasicrysial, was recently produced by pulse current electrodeposition. However, the surface finish was not sufficiently smooth. In this paper, pulse reverse current, as an alternative to the use of levelling additives, was employed in the electrochemical deposition of nickel-quasicrystal composite coating. The effect of anodic time on volume percentage of embedded quasicrystal particles, surface finish, and microhardness of the composite coating was examined. With a rise in anodic time, an improved surface finish was obtained, the volume percentage reduced, and microhardness decreased.
