“…As shown in Figure a, the total WV of tribopairs presented a good linear correlation with the dissipated E f as where the unit of E f is mJ and that of WV is μm 3 . The fitted form of eq is consistent with the results obtained in previous studies. ,,,, E f maintains a linear relationship with μ multiplied by F n and S . Meanwhile, according to the Holm–Archard equation, WV presents a linear relationship with the product of F n and S .…”

“…The energy concept has been used as an effective tool for analyzing the running-in process. From the energy perspective, the input friction force multiplied by the sliding distance ( S ) corresponds to the frictional energy ( E f ), which is often dissipated in several ways: (1) frictional heat with increases in temperature and mechanical vibrations, (2) wear generation (worn surfaces and abrasive particles), and (3) changes in the physical properties of solid surfaces, such as plastic deformation. − Among them, wear is a progressive loss of solid surface materials depending on various parameters, including the normal load ( F n ), sliding velocity ( v ), S , and the hardness of tribopairs ( H ). , Several classic models have been proposed to characterize material wear. ,− The wear volume ( WV ) is proportional to F n × S based on the Coulomb friction model. The Holm–Archard equation presented a proportional relation between WV and F n × S / H .…”

Recently, many studies have reported the ultralow friction coefficient of sliding friction between rigid solid surfaces in aqueous lubrication. A running-in process that goes through high-friction and friction-decreasing regions to a stable ultralow friction region is often required. However, the role of the friction-decreasing region is often ascribed to tribofilm formation in which complexity hindered the quantitative description of the running-in process and the prediction of its subsequent lubrication state. In this work, the frictional energy (E f) dissipated in the running-in process of a poly(oligo(ethylene glycol) methyl ether acrylate) aqueous lubrication was related to the wear of solid surfaces under different conditions and lubrication states. Experimental results indicated that the high-friction region was in a boundary lubrication state, contributed to most of the wear, and significantly reduced the contact pressure, whereas the friction-decreasing region was in a mixed lubrication state, contributed only to the slight and slow removal of materials, and slightly reduced the contact pressure. Therefore, by establishing relationships among the wear scar diameter, E f, and the Stribeck curve of the tribological system, the subsequent lubrication state after a running-in process under various working loads and sliding speeds could be quantitatively predicted. The running-in experiments with different aqueous lubrication systems showed good agreement with the prediction of this method. This investigation provides an effective method for the wear and lubrication state prediction after a running-in process, further proving the importance of the Stribeck curve for a lubrication system. This study may also have important implications for the strategy design of the running-in process in various industrial applications.

“…Unfortunately, also wear specific energy is not univocally determined, therefore, representation of frictional energy vs mass loss is herein considered as a good way for comparing tribological characteristics also according to [29,30] considerations. Other representation could be used, Jahangiri et al [20] for example, defined the wear specific volume (wear volume/dissipated energy (mm 3 /J)). Both representations can be used as a substitute of the traditional wear rate because of the simultaneous involvement of several wear parameters and of its strong dependence on the wear mode.…”

“…For example, the wear performance of a metal have been presented in wear rate, 17 weight loss, 18,19 volume loss [20][21][22][23] specific wear rate and/or wear resistance. 24,25 Each form introduces different understanding and trends to the results which in turn makes the results to become misleading and the data incomparable. Therefore, the authors highly recommend presenting the wear performance of materials in terms of specific wear rate, which represents the volume loss per applied load and sliding distance.…”

Understanding the wear mechanism significantly contributes to the knowledge of tribology of common metals and assists in predicting, overcoming and preventing the failure of designed components. In the current study, wear and frictional performances of brass, aluminium and mild steel metals are investigated at different operating parameters, i.e. sliding durations (0–10 km) and applied loads (0–50 N) against stainless steel counterface under dry contact conditions. The experiments were performed using block on ring machine. To categorise the wear mechanism and the damage features on the worn surfaces and the collected debris, scanning electron microscopy was used. Thermal imager was used to understand the heat distribution in the contacted bodies and the interface regions. The results revealed that the operating parameters influence the wear and frictional behaviour of all the metals. Brass metal exhibited better wear and frictional behaviour compared to others. Three different wear mechanisms were observed, i.e. two-body abrasion (brass), three-body abrasion (aluminium) and adhesive (mild steel).
