- The SUROS rolling-sliding testing machine at the University of Sheffield has been developed to examine the wear and early rolling contact fatigue performance of materials by laboratory simulation. This paper describes the construction, operation and capabilities of the twin disc testing machine and presents some of the results obtained during a study of the performance of a back-up material when run under conditions of water lubricated rolling-sliding contact with test discs manufactured from high speed steel to represent the work roll. In particular, the work presented was obtained from a test programme carried out to study the effect of work roll test disc surface roughness on the surface wear and early surface crack formation in back-up roll test discs manufactured form a cast back-up roll material. The results showed that under certain conditions, early surface cracks seen in the back-up roll test discs were similar to those seen in the surface of a sample taken from spalled material from a back-up roll. In addition the results showed that the roughness of the work roll test disc has a very significant effect on both the initiation and early propagation of surface cracks and also the surface wear rate of the backup roll test disc track.
