“…Wear rate and coefficient friction values obtained for various compositions of composites are tabulated in Table .1. From the results, it was evident that additions of tungsten carbide reinforcement enhance the wear resistance and the results are in good agreement with few literatures [3] [5]. The plot obtained from the pin-on-disc tribometer's software is depicted in fig.…”

“…Carbide, Molybdenum Sulphide, Muscovite, Waste Porcelain are other reinforcement materials which when reinforced with soft aluminium matrix enhances the wear behaviour of the composites as reported in many literatures. [5][6][7][8][9][10].Vibration damping is one of the important requirements of the material when using it as machine base, frame, mountings and other supports. If the material's resistance to vibration or absorption of vibration energy is predominant, the ill effects in the mechanical systems will be greatly minimized [11][12][13][14].Vibration properties like damping factor and natural frequency of the Aluminium based composites were investigated by many researchers and reported that the reinforcements enhances the natural frequency and damping factor [13][14][15][16][17].…”

In this research, vibration damping property and dry sliding wear resistance of tungsten carbide reinforced aluminium AA6061 composites were investigated. The fabrications of test specimen were carried out using stir casting method. Three samples were taken for study with percentage of reinforcements as 0%, 4% and 8% of tungsten carbide by volume fraction. The samples are cut and machined to cylindrical pin as per ASTM standard for pin-on-disc wear analysis. Another set of samples with rectangular cross section is used as beam for experimental modal analysis using Impact hammer test to study the damping factor and natural frequency. Based on the test results, it was found that there is minimum wear resistance in reinforced alloy when compared to unreinforced alloy and also reinforced alloy had improved coefficient of friction. From the impact hammer test, the result shows that reinforced alloy had high natural frequency and improved damping factor when compared with unreinforced alloy. The hard ceramic tungsten carbide particulate improves the resistance to wear as well as improved the damping behaviour. This research can be helpful in many industrial application, heavy machineries, automotive applications This material can be developed to use as machine base, chassis where wear resistance and vibration damping needs to predominantly monitored.

“…Tribological tests were performed using a pin-on-disc tribometer as described elsewhere. 25–30 All of the experiments were performed under oil lubricating and laboratory conditions (temperature, T = 25 ℃, relative humidity ∼50%). The lubricating oil used in the test was Shell Rimula R3 Multi 10 W-30 oil and the flow rate was about 2.5 mL/min.…”

In this article, the tribological behaviors of CuPb24Sn under different load and oil lubrication conditions were studied. The worn surface, material transfer, and debris of the material were analyzed by the scanning electron microscopy and energy-dispersive X-ray spectrometer. In addition, the wear rate of CuPb24Sn was measured by means of a laser microscopic 3D and profile measurement apparatus. The results show that the soft phase lead wears preferentially from the sample surface under both light and heavy load conditions. Under the light load condition, the wear rate of the soft phase lead is low. Therefore, in this condition the samples are lubricated by oil and surface residual lead, and the wear mechanism is mainly abrasive wear. However, under heavy load conditions, the soft phase lead is quickly consumed. The lubricating oil film is thinner and the asperities contact is increased. And then the surface temperature and oxidation of samples are increased too. In this case, the main wear mechanisms of samples are adhesive wear and oxidation wear. At the same time, with the depletion of lead, cracks begin to form and propagate at the interface between lead and copper, and then peel off from the matrix to form wear debris, which further accelerates the wear of the sample.

“…For example, it is theoretically expected that nanophases with a size smaller than 100 nm into metals/alloys could overcome the tradeoff between strength and ductility [9], whose synergy is beneficial for anti-wear performance. The typical nanophases into metals and alloys for tribological applications include carbides (TiC [10], NbC [11], WC [12,13], ZrC [13], B 4 C [14], and SiC [15,16]), borides (TiB 2 [7] and ZrB 2 [17]), nitrides (AlN [18], TiCN [19], TiN, BN [20], and Si 3 N 4 [21]), oxides (mainly Al 2 O 3 [22]; SiO 2 [23], TiO 2 [24], and other oxides [25,26] are not frequently used), sulfides (mainly MoS 2 [20,27], possibly with other sulfides [28]), and other dimensionally special materials like carbon nanotube (CNT) [29], grapheme [30], diamond [9,31], etc.…”

Metal matrix nanocomposites in tribology: Manufacturing, performance, and mechanisms

Metal matrix nanocomposites (MMNCs) become irreplaceable in tribology industries, due to their supreme mechanical properties and satisfactory tribological behavior. However, due to the dual complexity of MMNC systems and tribological process, the anti-friction and anti-wear mechanisms are unclear, and the subsequent tribological performance prediction and design of MMNCs are not easily possible: A critical up-to-date review is needed for MMNCs in tribology. This review systematically summarized the fabrication, manufacturing, and processing techniques for high-quality MMNC bulk and surface coating materials in tribology. Then, important factors determining the tribological performance (mainly anti-friction evaluation by the coefficient of friction (CoF) and anti-wear assessment with wear rate) in MMNCs have been investigated thoroughly, and the correlations have been analyzed to reveal their potential coupling/synergetic roles of tuning tribological behavior of MMNCs. Most importantly, this review combined the classical metal/alloy friction and wear theories and adapted them to give a (semi-)quantitative description of the detailed mechanisms of improved anti-friction and anti-wear performance in MMNCs. To guarantee the universal applications of these mechanisms, their links with the analyzed influencing factors (e.g., loading forces) and characteristic features like tribo-film have been clarified. This approach forms a solid basis for understanding, predicting, and engineering MMNCs’ tribological behavior, instead of pure phenomenology and experimental observation. Later, the pathway to achieve a broader application for MMNCs in tribo-related fields like smart materials, biomedical devices, energy storage, and electronics has been concisely discussed, with the focus on the potential development of modeling, experimental, and theoretical techniques in MMNCs’ tribological processes. In general, this review tries to elucidate the complex tribo-performances of MMNCs in a fundamentally universal yet straightforward way, and the discussion and summary in this review for the tribological performance in MMNCs could become a useful supplementary to and an insightful guidance for the current MMNC tribology study, research, and engineering innovations.
