Subsequently, the relative movement causes the cold-weld junctions to be broken and eventually led to tear off of materials from both side. 3.1.3 Fatigue wear Figure 4 shows a typical contact fatigue wear debris characterized in irregular shape, intercrossing and enrichment of fatigue micro-cracks, coarse surface appearance, large in thickness, evidence of sliding scars.
In the process of relative movement of two contact bodies, corrosive media may cause chemical or electrochemical reactions that result in materials loss.
