Özet
In this study, Ni/Al2O3 metal matrix composite (MMC) coatings were prepared from a modified Watt's type electrolyte by direct and pulse current (DC and PC) plating methods, and the effect of current density is investigated. The tribological tests were performed by a reciprocating ball-on disk apparatus sliding against M50 steel ball (Ø 10 mm). The wear tests were carried out at different sliding velocities of 50 mm/s, 100 mm/s and 150 mm/s by using a constant load. Increasing sliding velocity resulted in increasing wear rate in DC produced coatings but decreasing in PC co deposited materials.
