Abstract
The effect of silver particle introduction on the rolling friction of AISI 52100 steel pairs has been investigated. Experiments were performed in dry conditions using a thrust bearing-type rolling test rig at a load range of 12 - 960 N and a sliding velocity range of 8 - 785 mm/sec with pure (99.99%) silver particles. Results showed that introduced silver paricles formed trasnfer layers, which protected the virgin bearing surfaces. and resulted in the low rolling friction. By changing the quantity of silver particles, transitoins in the rolling friction were found. Results also showed that the variations in normal load and rolling speed also affected the rolling friction behavior. Analyses of SEM and EPMA showed that the formation of transfer layer was mainly groverned by the silver particle auantity, normal load and rolling speed, and this resluted in the different behavior of rolling firction. In this study, it was found that the low and stable rolling friction was resluted from shakedown phenomena occurred at the silver transfer layer.
