“…In the first approach, The wear equations proposed by Archard [19] and Holm [64] cannot differentiate or explain the types of adhesive wear. Rather than deciding based on the probability of the removal of wear debris merely by the wear coefficient [74], the removal of wear particles from the contact surface must necessarily be dependent on the operating conditions, interfacial adhesion/friction conditions, and the physical, chemical, and mechanical properties of the contacting pairs [28,[75][76][77].…”

An extensive survey of open literature reveals the need for a unifying approach for characterizing the degradation of tribo-pairs. This paper focuses on recent efforts made towards developing unified relationships for adhesive-type wear under unlubricated conditions through a thermodynamic framework. It is shown that this framework can properly characterize many complex scenarios, such as degradation problems involving unidirectional, bidirectional (oscillatory and reciprocating motions), transient operating conditions (e.g., during the running-in period), and variable loading/speed sequencing.

“…Refs. [11,12,53] reports that the wear resistance of Cu-Zn alloys increases with zinc concentration from 8 to 25 wt% Zn and improved resistance to galling with decreasing SFE. It needs to be mentioned that the opposite trend was reported for aluminum bronze alloys [54,55], while other authors did not find any correlation [51].…”

“…The tribological performance of copper and copper alloys in a sliding contact has been extensively investigated in the past [9][10][11][12][13][14][15][16][17][18][19]. Korres et al [10] studied the wear behavior of copper during a frictional contact with steel pins.…”

“…Early studies by Taga and Nakajima [9] concerning the non-lubricated tribological behavior of brass indicated that the frictional properties of -brass can be enhanced by increasing the amount of zinc. Experimental contributions from Paretkar et al [11,12] aimed to find a defined amount of zinc in brass alloys to optimize their tribological performance; however, these studies were not successful in finding an optimal solution due to the complex nature of tribological loading.…”

Tribological performance and microstructural evolution of α-brass alloys as a function of zinc concentration

Tailoring a material's properties for low friction and little wear in a strategic fashion is a long-standing goal of materials tribology. Plastic deformation plays a major role when metals are employed in a sliding contact; therefore, the effects of stacking fault energy and mode of dislocation glide need to be elucidated. Here, we investigated how a decrease in the stacking fault energy affects friction, wear, and the ensuing sub-surface microstructure evolution. Brass samples with increasing zinc concentrations of 5, 15, and 36 wt% were tested in non-lubricated sphere-on-plate contacts with a reciprocating linear tribometer against Si 3 N 4 spheres. Increasing the sliding distance from 0.5 (single trace) to 5,000 reciprocating cycles covered different stages in the lifetime of a sliding contact. Comparing the results among the three alloys revealed a profound effect of the zinc concentration on the tribological behavior. CuZn15 and CuZn36 showed similar friction and wear results, whereas CuZn5 had a roughly 60% higher friction coefficient (COF) than the other two alloys. CuZn15 and CuZn36 had a much smaller wear rate than CuZn5. Wavy dislocation motion in CuZn5 and CuZn15 allowed for dislocation self-organization into a horizontal line about 150 nm beneath the contact after a single trace of the sphere. This feature was absent in CuZn36 where owing to planar dislocation slip band-like features under a 45° angle to the surface were identified. These results hold the promise to help guide the future development of alloys tailored for specific tribological applications.

“…Significant research effort has been devoted to study the dependence of adhesive wear on various factors, such as normal load, sliding speed, interfacial adhesion/friction conditions, and material properties (Lisowski and Stolarski, 1981;Finkin, 1972;Paretkar et al, 1996;Yang, 2003). Archard's wear model has been used extensively to quantify the wear rate of sliding surfaces (Qureshi and Sheikh, 1997;Yang, 2004), develop adhesion models of single-asperity junctions (Rabinowicz, 1980), and perform energybased analyses of adhering asperities (Warren and Wert, 1990).…”

a b s t r a c tA generalized adhesive wear analysis that takes into account the effect of interfacial adhesion on the total load was developed for three-dimensional fractal surfaces in normal contact. A wear criterion based on the critical contact area for fully-plastic deformation of the asperity contacts was used to model the removal of material from the contact interface. The fraction of fully-plastic asperity contacts, wear rate, and wear coefficient are expressed in terms of the total normal load (global interference), fractal (topography) parameters, elastic-plastic material properties, surface energy, material compatibility, and interfacial adhesion characteristics controlled by the environment of the interacting surfaces. Numerical results are presented for representative ceramic-ceramic, ceramic-metallic, and metal-metal contact systems to illustrate the dependence of asperity plastic deformation, wear rate, and wear coefficient on global interference, surface roughness, material properties, and work of adhesion (affected by the material compatibility and the environment of the contacting surfaces). The analysis yields insight into the effects of surface material properties and interfacial adhesion on the adhesive wear of rough surfaces in normal contact.
