“…This may be due to the fact that a graphite-free reference material was missing, or, that the composition of the friction material was already too complex. The same holds for a recent study by Ram Prabhu, who also could not elaborate a clear effect of graphite addition to a MMC friction material in contrast to MoS 2 addition [21]. There are some other studies on copper-based MMCs which show clear effects of graphite additions on triboligical properties [22,23].…”

This review article comprises of three parts. Firstly, reports of brake manufacturers on the beneficial impact of solid lubricants for pad formulations are surveyed. Secondly, since tribofilms were identified to play a crucial role in friction stabilization and wear reduction, the knowledge about tribofilm structures formed during automotive braking was reviewed comprehensively. Finally, a model for simulating the sliding behavior of tribofilms is suggested and a review on modelling efforts with different model structures related to real tribofilms will be presented. Although the variety of friction composites involved in commercial brake systems is very broad, striking similarities were observed in respect to tribofilm nanostructures. Thus, a generalization of the tribofilm nanostructure is suggested and prerequisites for smooth sliding performance and minimal wear rates have been identified. A minimum of 13 vol % of soft inclusions embedded in an iron oxide based tribofilm is crucial for obtaining the desired properties. As long as the solid lubricants or their reaction products are softer than magnetite, the main constituent of the tribofilm, the model predicts smooth sliding and minimum wear.

“…This was owed to the intensification of consistent dispersal of MoSi 2 particulates with the matrix phase. Ram Prabhu et al [17] decided that the composite material that were sintered with 1000°C had superior densification and it resulted in augmented wear resistance and breaking function of the composite materials. Senthil Kumar et al [18] have discovered that the hardness of the composite material is enhanced by amplifying the wt% of MoS 2 particles.…”

This investigation studies the dry sliding wear behavior of Al-4Mg matrix composites reinforced with different wt% of molybdenum disulfide (2, 4 & 6 wt%) produced using powder metallurgy route. The processed powders are initially characterized by Scanning Electron Microscopy (SEM) equipped with Energy Dispersive x-ray Spectroscopy (EDS). To authenticate the decisive distribution of the reinforcement particles with the matrix material, SEM analysis has been employed. The wear test is conducted on a pin-on-disc machine based on L 27 orthogonal array with three control factors (three level) sliding velocity (0.5, 2.0, 3.5 m s −1 ), applied load (5, 15, 25 N) and sliding distance (500, 750, 1000 m) to inspect the responses namely wear loss and coefficient of friction. Moreover, the worn surface and wear debris analysis of the composite pin surface have been examined through SEM to identify the wear mechanism. It has been identified that the development of lubricant layer is diminished by increasing the wt% of MoS 2 particulates and the wear loss is diminished. Likewise, diminutive debris have attained in the worn surface of Al-Mg-6 wt% MoS 2 composite material, since effectual solid lubricant properties have been exposed. Higher plastic deformation is attained at amplified load and it affects the pin surface and thus, Coefficient of Friction (COF) is augmented.

The use of nanofluid in lubrication during machining of advanced engineering ceramics has been found to be highly efficient and eco-friendly. This work involves experimental investigation of grinding Alumina (Al 2 O 3 ) ceramic to determine the effect of the grinding variables. The grinding variables considered include depth of cut, feed rate, type of diamond wheel, and lubrication type. Moreover, the response parameters considered include grinding power, coefficient of friction, and surface quality. The responses obtained during the experiments were used to develop a fuzzy logic prediction model. The findings from this work can be concluded as follows: (a) The depth of cut and feed rate have direct proportional relationship with the grinding power and coefficient of friction. (b) The metallic bonded diamond wheel was found to have higher machining efficiency than the resinoid bonded one. (c) Higher number of diamond grits produces lower frictional coefficient. (d) The carbon nanotube based nanofluid when used in the minimum quantity lubrication (MQL) process proffers better lubrication capability than conventional flood cooling system. (e) The developed fuzzy logic models were found to have high prediction accuracies of 97.22%, 98.60%, and 96.8%, respectively, for grinding power, grinding force ratio, and surface roughness.
