“…it is found that graphite of uncoated nickel tends to have poor interfacial bonding with the matrix material. But the 15% nickel coated graphite composites produce mechanically mixed layer that tends to have higher specific wear rate, high hardness and higher friction coefficient [18,19]. in addition to the above investigations, a special attempt of copper composites with lubricating phase particles like Mos 2 , Ws 2 , graphite and glassy carbon of 5 to 20% produced by stir casting and powder metallurgy route.…”

Among different bearing materials, copper-based alloys are the most important source for bearing and bushing applications. in this work, the tribological behavior of a leaded tin bronze (Cu-22Pb-4sn) against an en31 steel for various loads (20 n, 70 n, 120 n) and different sliding velocity (1 m/s, 3 m/s, 5 m/s) at 3000 m sliding distance is performed using a pin on disk tribometer. irrespective of all loads and sliding velocity, a higher specific wear rate is observed at 1 m/s and 120 n that fails to facilitate the formation of lubricating film, whereas a lower specific wear rate is evident when the sliding velocity is increased to 5 m/s. This is attributed to the formation of a stable oxide layer that has been confirmed through the energy dispersive X-ray spectroscopy analysis and scanning electron microscopy. The coefficient of friction is observed in reducing trend from 0.69 to 0.48 for the increasing load (70 n, 120 n) and sliding velocity (3 m/s and 5 m/s) due to stable thin oxide film formation. Also, the increase in frictional force and loading the interacting surface temperature is increased to a maximum of 102°C. The grey relational analysis indicates that the optimal parameters for the minimum specific wear rate and coefficient of friction is 120 n and 5 m/s that has been confirmed with experimental analysis.

“…On the other hand, modern criteria could barely be reached with the advent of equipment for high power, large loads, greater temperatures and speeds and wearing capabilities strength for copper and its alloy components under boundary lubrication [39,40]. Copper and its alloys under boundary and mixed lubrications have piqued the interest of several researchers [41,42].…”

The present study reports the tribological performance of a novel hybrid nano-lubricant for bronze/AISI 4340 alloy-steel tribopair. The hybrid nano-additive used in the present study helps to improve the lubricity and can sustain under extreme conditions. Initially, friction and wear properties are recorded by varying concentrations of Al2O3 (0.5, 0.8, 1.0, and 1.5 wt. %) and GNP (0.05, 0.1, 0.2, and 0.5 wt. %). Based on the results, an optimum hybrid concentration (OHC) is prepared by adding 0.8 wt. % of Al2O3 and 0.2 wt. % of GNP which resulted in 83.84% and 79.75% reductions in coefficient of friction (COF) in comparison to optimum Al2O3-based and GNP-based lubricants, respectively. However, the wear volume (WV) for OHC lubricant indicated 98.28% and 75% reduction in comparison to the abovementioned lubricants, correspondingly. Extreme pressure (EP) tests were carried out and OHC lubricant reported improved weld point for hybrid nano additive-based lubricant.

“…Bronze is extensively used in the industrial field, and many studies have been done on bronze (He et al , 2015; Prasad, 2012; Tavakoli et al , 2008; Ünlü and Atik, 2010; Yasar et al , 2009). However, the aluminum bronze still receives less attention in studies.…”

Purpose The purpose of this paper is to study the frictional behaviors of CuAl10Fe3 journal bearings sliding against chromium electroplated 42CrMo shafts and diamond-like carbon-coated 42CrMo shafts, respectively, under two different conditions and to compare the two kinds of friction pairs. Design/methodology/approach All journal bearing samples underwent 24 h running-in and repeatability verification. Then, the journal bearing friction experiments were carried out under two different conditions. After testing, the torques, friction coefficients, power consumptions and other parameters were obtained. Findings The pair of CuAl10Fe3 journal bearing and diamond-like carbon–coated shaft could drive greater load to start up than the pair of CuAl10Fe3 journal bearing and chromium electroplated 42CrMo shaft, but it had greater power consumption during the steady running period under the identical condition. With the changing of specific pressure or rotational speed, the friction coefficients had different variations. The frictional oscillations appeared at 32 rotations per minute under heavy loads for both kinds of pairs, the oscillation frequencies were equal to rotational frequency of the test shaft and the oscillation amplitude for diamond-like carbon coating was much greater. Originality/value These results have guiding significance for practical industrial applications.
