Tribology science is one of the applied sciences in mechanical engineering which focuses on the investigation of interacting surfaces in relative motion and its consequences. This science is related to the friction, wear and lubrication which control the lifespan of the contacting system. Some of the mechanical components such as: gears, wheels and rails, and roller bearings perform the rolling-sliding contact on their contacting surface. For example in the spur gears contact, the engineer should consider the contact pressure, deformation, and wear fundamentally in order to get the best performance. This paper objective is reviewing some rolling-sliding contact model and to choose the appropriate model to be combined with the developed ellipsoid contact model. The combination between rolling-sliding contact model with developed contact model will be applied in micro-scale contact on the real engineering surface. The stick-slip regions between the two contacted surfaces acts as the factor in determining the rolling-sliding contact situation. The finite element analysis (FEA) is used to compare one of the published rolling-sliding contact model. A good agreement is found one of analytical model, FEA model and the recent FEA results. The transient in rolling-sliding contact occurs at the start of rolling contact and it is followed with the steady state situation.
