Unlubricated sliding friction and wear of steels: An evaluation of the mechanism responsible for the T1 wear regime transition

Effect of Cu particles as an interfacial media addition on the friction coefficient and interface microstructure during (steel/steel) pin on disc tribotest

“…The friction coefficient values (Fig. 2) for the three systems -Cu50n It has been reported by Viáfara and Sinatora [22] that performing a sliding test with removal of wear debris demonstrates the significant contribution of wear particles on the friction phenomenon. In their work, the cyclical removal of debris from the contact surface resulted in cyclical decreases of the friction coefficient from 0.6 to 0.3.…”

Numerical and experimental analysis of dynamic oblique impact: Effect of impact angle

“…It can occur from mild to severe (called T1) or from severe to mild (called T2). According to Viáfara's works, the T1 and the distance-dependent transitions are closely related [16]. Two main assumptions have prevailed to explain the causes of wear transition T1.…”

Potentiality of triboscopy to monitor friction and wear

“…The effect of the accumulation of wear debris on friction has been reported in the literature [22][23][24][25]. Another interesting point is that when systems such as brushes [23], felts [24] or even gravity [25] were used to remove the debris from the wear track; friction and wear were significantly reduced.…”

“…Another interesting point is that when systems such as brushes [23], felts [24] or even gravity [25] were used to remove the debris from the wear track; friction and wear were significantly reduced. A more detailed investigation of the effect of the accumulation of wear debris within the wear track, including the use of techniques to remove wear debris, is currently under development.…”
