Abstract
The present study describes the
tribological properties of penetrated-graphite bronze containing
micro-sized sulfide under dry conditions. The graphite penetration
was carried out by means of roller burnishing. Micro shot peening
was also applied in order to fabricate micro dimples in the
penetrated graphite. The graphite area fraction was approximately
50%. The tribological properties were evaluated using a face-to-face
type testing apparatus under dry conditions. The results showed that
the friction coefficient of the sulfide-containing bronze decreased
and the seizure resistance properties significantly increased. The
friction distance until seizure occurrence was improved to more than
2.5 times. Furthermore, the friction coefficient was low and stable
until the end of the experiment. It was inferred that the friction
resistance was decreased and stabilized when the transfer layer was
without Fe content.
