“…When ductile material (i.e., C93200 alloy) slid over the counterface (EN-31 hardened steel disc) at a high load and sliding velocity, its ductility increased due to high frictional heat, and the unfilled composites’ pin surface was ploughed by the hard and sharp asperities of the counterface. Jin et al [33] performed the sliding wear test on Mg 2 B 2 O 5 whisker reinforced 6061 Al matrix composite, and reported a similar observation in their investigation. Similarly, when composites reinforced with 4.5 wt.% (A-4) marble content were run at a sliding velocity of 2.61 m/s, less wear loss was observed, but when the same composite was run at a higher sliding velocity (4.69 m/s) a slightly higher wear loss was observed.…”

Copper-based alloy (C93200) composites reinforced with a different weight percentage of marble dust particles (1.5, 3, 4.5, and 6 wt.%) were developed by stir casting method under vacuum environment. By using this type of reinforcement, it was possible to detect a suitable material for bearing applications. The manufactured material was characterized for its mechanical properties using a micro-hardness tester. A universal INSTRON-5967 machine was used to detect the yield and tensile strength. Further the hardness features were measured using a Walter Uhl model machine, whereby the wear characteristics were simulated under the pin-on-disc tribometer under different working conditions in ambient temperature (23 °C). Next, the preference selection index (PSI) technique that considers multi-criteria decision-making was proposed to validate which material was the best candidate. For the selection of material criteria, some specific material intrinsic properties—such as, density, void fraction, hardness resistance along with tensile, compressive, and flexural strength—were proposed and the surface characteristics linked to friction coefficients along wear properties. It was found that the novel composite material containing 4.5 wt.% of marble dust provided the best combination of properties and is a suitable candidate material for bearing applications.

“…After softening, the shear strength of nylon decreases, and the material continuously falls off from the surface, which makes the abrasion amount increase . The modified Mg 2 B 2 O 5 w had a better interface with the OMC nylon matrix, better dispersion in the matrix and this modified Mg 2 B 2 O 5 w located on the friction surface played the role of bearing wear and shear due to their high wear resistance and high strength properties . Having self‐lubricating property of oil helped to reduce the friction coefficient of the composites.…”

The Mg 2 B 2 O 5 w modified by toluene-2, 4-diisocyanate (TDI) and fatty amine (n-dodecylamine(D) or n-octadecylamine (O)) was used in oil-containing monomer casting (OMC) nylon, and the effect of modified Mg 2 B 2 O 5 w on mechanical and friction properties of OMC nylon composites was investigated. The significant improvement of the mechanical and friction properties of composites was observed. The addition of 0.15 wt% TDI-D-Mg 2 B 2 O 5 w or TDI-O-Mg 2 B 2 O 5 w resulted in 21 and 20% growth in the tensile strength, 53 and 52% increase in the flexural strength, respectively. Additionally, nearly 60 and 58% reduction in the friction coefficient, about 84 and 80% decrease in the abrasion quantity. Furthermore, the worn surface of composites exhibited smooth, which confirmed the antiwear effect of Mg 2 B 2 O 5 w. The improvement was attributed to the interfacial adhesion between whiskers and matrix by hydrogen bonds. This work provided a facile approach to the design of wear-resistant polymer composites that hold significant potential in construction machinery industry.
