Abstract
To improve the tribological properties of sliding surfaces, various surface treatment methods are used. Fine Particle Peening (FPP) is one of the methods which have attracted considerable attention recently.
In this study, a SiC-rich layer was created on the treated surface of carbon steels (S45C) by FPP using SiC shot particles (average diameter: 19,34,88 μm). The tribological properties of the FPP treated carbon steels were examined by sliding experiments. The experiments were performed in the atmosphere and 3% NaCl solution. A ball-on-disk type testing equipment was used in the sliding experiments. These were carried out under a normal load of 20N at a sliding speed of 0.1m/s and a sliding distance of 180m.
The results show that the tribological properties of the FPP treated carbon steel were improved in comparison with FPP untreated ones. Further improvements were obtained by buffing.
