Surface Topography and Surface Contaminants,– 10°. Unlubricated metal surfaces encountered in an industrial environment will, in general, be covered by a whole series of surface films, as shown in Fig. 4.1. Working outwards from the metal interior, we first encounter an oxide layer, produced by reaction of oxygen from the air with the metal;

Stress Domains, Relaxation, and Creep,hat the lubrication film at low sliding velocities has a granular structure, with pinned adsorbate domains accompanied by elastic stress domains in the block and substrate. At zero temperature, the stress domains form a “critical” state, with a continuous distribution .(.) of local surface stresses

Lubricated Friction Dynamics,ree end of the spring is moving with the velocity ... Depending on the parameter values (.., ..) the motion of the block may be either steady or of stick-slip nature. In this chapter we discuss the nature of the (.., ..) phase diagram, i.e., the regions in the (.., ..)-plane where the motion is stea

Dry Friction Dynamics, layer of grease, even if no lubrication fluid has been intentionally added to the system. Nevertheless, in some cases the increase of the static friction force with the time of stationary contact, due to the processes discussed in Chap. 12, may be negligible; we will refer to these systems as exhib
