- Abstract
In this study, the wear behavior of cold worked (Ballised) CuSn5 bushings was investigated. Ballising is a kind of cold working process applied to hole surface which impart negative residual stresses. The ballising process improves wear-fatigue resistance of the hole surface. CuSn5 bushings were fabricated by centrifugal casting in a steel pipe. From 5 mm to 500 mm interferences were used for ballising level. The abrasive wear tests were conducted by using a pin-in-ring type tribometer. The effects of sliding time and ballising interference (cold working ratio) on the abrasive wear properties of the CuSn5 bushings were evaluated. The effect of ballising interference on pushing forces, dimensional deviation of inner-outer diameter, surface roughness, micro hardness and wear resistance were also evaluated. It was observed that the dimensional deviation, micro hardness and wear resistance were increased with ballising interference levels. Moreover, the wear resistance of the ballised bushings were found to be considerably higher than that of the non-ballised bushings and increased with increasing the cold working ratio which depends to ballising interference level. The successful application of the ballising results lower production cost and improves the performance of bushings in real industrial applications.
