ABSTRACT This study is focused on the performance evaluation of three cutting lubricants, which are neem, palm kernel and mineral oil in the turning of AISI 1045 with MQL. Optimization of machining parameters with multi-response signals using Taguchi-based grey relational analysis was done. For experimental design, tests were developed using Taguchi's L9 orthogonal array and the signal-to-noise ratio was obtained using the smaller-the-better approach to achieve the optimal combination. Performance indicators including surface roughness and cutting temperature were measured throughout the machining process. Neem oil performed best among the oils for surface roughness while mineral oil outperformed them all for cutting temperature, according to the experimental results. The optimum spindle speed, feed rate and depth of cut for neem, palm kernel and mineral oils are 870 rev/min, 0.25 mm/rev and 1.25 mm; 870 rev/min, 0.10 mm/rev and 0.75 mm; and 415 rev/min, 0.10 mm/rev and 1.00 mm, respectively.

ABSTRACT 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 above-mentioned lubricants, correspondingly. Extreme pressure (EP) tests were carried out and OHC lubricant reported improved weld point for hybrid nano additive-based lubricant. GRAPHICAL ABSTRACT

ABSTRACT Environmental concerns and depleting mineral oil resources have forced us to develop environmentally acceptable lubricants. In this study, tribological properties of rice bran oil containing imidazolium-based ionic liquid 1- ethyl 3methylimidazolium dicyanamide ([EMIM][DCN]) (ILa), phosphonium based ionic liquid Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl) phosphinate ([P66614][BTMPP]) (ILb) and titanium oxide (TiO2) nanoparticles (NPs) as hybrid additives have been investigated using four ball tester. Rice bran oil based ionanolubricants (INLs) were formulated with different concentrations of ILa, ILb and TiO2 NPs. Among all investigated ionanolubricant samples, rice bran oil containing 0.03 of TiO2 NPs and 0.5 vol.% of ILa showed the lowest AWSD. The improved characteristics of rice bran oil based INLs can be attributed to the ball bearing effect and tribofilm formation. GRAPHICAL ABSTRACT

ABSTRACT This research investigates the tribological characteristics and sustainability of WS2 deposited Al 6061-T6 surface under dry sliding conditions and optimizes the wear parameters to enhance the tribological behaviour and discuss its sustainability. The experiment used the Box–Behnken design, which examines the effective interaction between dry sliding parameters and specific wear rate (SWR) and friction coefficient (COF). By varying the load (L), sliding velocity (V) and distance (D), the wear behaviour of WS2 deposition against EN 31 steel was examined through the pin-on-disc experiment. Grooving, debris formation, polishing, tribolayer, ploughing, transfer material, smearing, delamination and pitting are observed through scanning electron microscope (SEM) analysis. For optimum conditions, SEM with energy dispersive spectroscopy was utilized to characterize the worn surface, and X-Ray diffraction (XRD) patterns confirmed the phases of W, WO3, WS2, Al, AlO, Al2S3 and Al4C3.

ABSTRACT The work-hardening and low thermal conductivity characteristics of SS304 had always been a challenge to machine it easily with better tool life and surface finish. The type of coolant, its temperature and surface coated inserts plays a pivotal role in machining the hard materials. A number of experiments were performed with a TiCN and tungsten carbide inserts in combination with soluble/synthetic coolant at ambient temperature and at 0oC TiCN-coated cemented carbide insert with synthetic coolant at 0°C is recommended for machining as per the results obtained through this research work. It was found that TiCN-coated inserts used for machining SS304 with synthetic coolant at 0°C provide better tool life, less tool wear, improved surface finish and low heat generation. The tool life was enhanced approximately by 75%, 20% reduction in maximum temperature generation and 50% improvement in surface finish of workpiece. GRAPHICAL ABSTRACT

ABSTRACT The composite materials are fabricated by combining various ingredients to make higher material properties as required by various industries. The primary classification of composites is based on their build ingredients, such as binder, fibre, reinforcement and fillers. The characteristics of individual ingredients influenced the properties of composites. Further, friction materials are those composite materials efficiently used in vehicles’ braking. Researchers have tried the various formulations of friction materials because it is very significant to study the mechanism and material characteristics due to the safety measures of vehicles. The current study examines the various brake composite materials’ characteristics and their mechanical and tribological performance in this article. The tribological study includes the various terminologies used in friction and wear using pin-on-disc, dynamometer, field studies, etc. The effects of numerous elements impacting the wear of frictional materials are given, and the tribological performances of used friction materials are given the utmost attention.

ABSTRACT The brake friction materials are composite materials with multi-ingredient systems which induce a complex formulation. This complexity is also the result of the manufacturing parameters effects, such as mixture sequence and duration, moulding pressure, time, temperature and heat treatment time. Therefore, heterogeneity is induced as well in the characteristics (microstructure, density, etc.) as in the behaviour (mechanical, tribological, dynamic, etc.). Despite the study of the effect of manufacturing parameters on the friction material behaviour, the synergistic effect between the heterogeneity and the braking performance is still not well reported. This paper strives to eliminate the cloud of uncertainty of the role of manufacturing parameters on the friction material performances by providing most used process of elaboration, and most required properties for contemporary brake system. Innovation in brake discs and pad manufacturing by optimized algorithms, prediction approaches, and 3D printing process is presented as innovative methods to improve braking materials performance.

ABSTRACT In this study, dry sliding wear behaviour of a copper alloyed austempered ductile iron (ADI) consisting of very fine ausferrite, small high carbon austenite blocks, was investigated against 100Cr6 ball using ball-on-disc tribometer. Tribotests were conducted at different loads of 10, 30, 50, and 100 N and speeds between 0.39 to 0.79 m/s. Worn-out surfaces and wear debris revealed tribe-oxidation and abrasive wear as the primary mechanism for material removal at lower loads and low speed (0.39 m/s). With an increase in load and speed, fragmented graphite nodules acted as solid lubricants. Additionally, partial transfer of tribo-oxide onto the counter-body ball, and plastic deformation and strain hardening of ADI matrix lowered the friction coefficient and wear rate at higher loads and speed, to nearly 1/3 and 1/10 as compared with those at lower loads and speed. The superior wear resistance of present ADI is worthy of consideration for transmission parts. GRAPHICAL ABSTRACT

ABSTRACT The tribological characteristics of stir cast Al-15%Si-10%Zn matrix with 15%ZrO2 reinforced composite were investigated. The microstructure of the Al-15Si alloy consisted of coarse primary Si and acicular eutectic Si phases randomly distributed in the Al dendrites. The Al-15%Si-10%Zn/ZrO2 composite showed spherical Si with a size between 25 and 75 µm; fragmented eutectic Si phase and uniform dispersion of ZrO2 particles in the matrix. The wear test was conducted using in a pin-on-disc method at different loads and sliding velocities. It was found reduced coefficient of friction, significant increase in the hardness and wear resistance of the composite compared to the matrix alloy. High wear resistance in the composite due to the effect of solid lubrication provided by Zn, and good fracture toughness and wear resistance by the reinforced ZrO2 particles. The predominant oxidative and abrasive wear were identified as the mechanisms leading to material failure through plastic deformation and delamination. GRAPHICAL ABSTRACT
