“…During the rolling wear tests, interfacial delamination, which resulted in the formation of wear debris, might have originated in the pores in the coating. Shear plastic deformation, crack initiation, and crack propagation near the surfaces would lead to lamination of the debris [22]. After the ECS treatment, the Ni-40% WC coating had a higher hardness than the rubbing pair and fewer pores, stronger cohesion and smaller grain size than the coating that was not treated by ECS.…”

“…Therefore, the wear resistance is one of the most important material properties for these types of applications, which consist of many mechanical joints. Furthermore, basic sliding wear mechanisms have been used as an interpretation of the wear rate in fretting wear [6,7]. Therefore, a better understanding of the basic wear mechanisms is required.…”

“…[15] The majority of these experimental investigations have been performed on materials that are not surface treated. In spite of extensive studies in the literature, [4][5][6][7] the origin of fretting fatigue damage is still not clear. Studies of fretting fatigue involving shot-peened surfaces are rare in the literature, although this issue is very important in industrial use.…”

The evolution of fretting fatigue damage was investigated in shot-peened Ti-6Al-4V samples, by measuring the changes in the surface residual stress, using the X-ray diffraction technique. The surface residual stress was found to relax as the number of fretting fatigue cycles increased. The relaxation behavior of the residual stress with the increasing number of fretting fatigue cycles was observed to occur in three stages. In the first 20 pct of the fretting fatigue life, a drastic relaxation was observed. In the second part (between 20 and 70 pct), a gradually increasing behavior was observed. During the last 20 to 30 pct of the fretting fatigue life, a dramatic relaxation of the residual stress was found to occur. A complete relaxation of the residual stress occurred in the fracture region. A scanning electron microscope observation of the microstructure of the damaged region was used to examine the mechanisms leading to the relaxation of the residual stress. The development of delaminations at the early stages of the accumulation of the fretting fatigue damage was observed to be the main cause of the initial relaxation. The generation of microcracks from the voids left behind by the delaminations is responsible for the additional relaxation of the residual stress. The coalescence of the microcracks generated from different delaminated regions produced yet more relaxation of residual stress and, ultimately, the final fracture of the specimen.
