• The authors investigated the effect of surface roughness of 0.45 % carbon steel on scoring in rolling/sliding contact under starved lubricating condition using a two-disc machine. The scoring resistance of carbon steel was significantly affected by the extent of work-hardening of disc surfaces and formation of the surface films during running-in. The disc with small surface roughness which was little increased in scoring resistance during running-in had a tendency to suffer scoring even under mild condition. Therefore, the intensity of the scoring resistance of the disc with small surface roughness showed duality, that is, scoring occurred under extremely mild condition, or under extremely severe condition depending on the formation of surface films and the work-hardening. On the other hand, the disc with rough surface was work-hardened and the surface films were formed on its surface. Therefore, its scoring resistance was high.
