Özet
In the present work, Ni/SiC metal matrix composite (MMC) coatings were prepared from a modified Watt's type electrolyte containing nano-SiC particles by direct current (DC) plating method to increase wear resistance of Ni. The influence of surfactant content on co-deposition of SiC particles (0.1-1.0 ?m size range) in the matrix, and tribological properties were investigated. The influence of sliding speed on the tribological performances of the coatings was investigated by a reciprocating ball-on disk apparatus. The wear tests were carried out at different sliding speeds by using a constant load. Wear resistances and friction coefficients of Ni/SiC composites were decreased by increasing sliding speed because of temperature-controlled surface oxidation. The change in wear mechanisms by changing surfactant content and sliding speeds were also comprehensively studied and, in general, decreasing surface damage was obtained by increasing sliding speed.
