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.eninfo:eu-repo/semantics/closedAccessElectro co-deposition; Nano-composite; Tribology; Wear mechanismsConference Object
