Effect of reinforcement in the fabrication of ZA-27 composites with hexagonal boron nitride (HBN) and graphite (Gr) nanoparticles through stir casting
Anuj Kumar, Gurinder Singh Brar
Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2026
Zinc aluminium alloy is widely used for bearing and load-bearing applications owing to its good castability, high strength and cost effectiveness; however, its wear resistance and frictional stability under higher loads remain a concern. While, individual reinforcement has not achieved an overall improvement in tribological performance of composites. The present study investigates the fabrication of ZA-27-based composites reinforced with hexagonal boron nitride (hBN) and graphite (Gr) nanoparticles using stir casting followed by ultrasonic treatment. The composites were reinforced with a fixed content of 2 wt.% hBN and varying proportions of Gr particles at 2, 4 and 6 wt.%. The dry sliding wear behaviour was examined using a pin-on-disc tribometer under applied loads ranging from 10 to 30 N. The outcomes demonstrated that the wear rate decreases with increasing reinforcement content. Compared to unreinforced alloy, volumetric wear loss of composites decreased by 13.80%, 22.23% and 46.26% for 2, 4 and 6 wt.% Gr reinforcement, respectively, at a load of 30 N. Energy-dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analyses confirmed the composition and phase stability of composites, while scanning electron microscopy (SEM) shown a uniform distribution of reinforcement particles. Worn surface analysis showed deep grooves and delamination in the matrix alloy, whereas the composites exhibited finer scratches due to the formation of a lubricating tribo-film. This investigation may serve as a reference for the development of ZA-27/hBN/Gr composites for advanced industrial tribological applications (such as automotive and marine components).

Proceedings of the Institution of Mechanical Engineers Part B Journal of Engineering Manufacture, 2026
In the current research, a novel ceramic matrix composite with a high proportion of mullite matrix and SiC reinforcement was fabricated by the powder metallurgy process. The effects of material composition, hydraulic press load, and sintering temperature were investigated by characterizing fabricated composites by evaluating porosity, surface roughness, and tribological behaviour by dry sliding wear testing at room temperature using pin-on-disc apparatus. The multicriteria decision analysis optimization technique using grey relational analysis (GRA) was carried out, and the optimized fabrication parameters were determined. The results obtained from GRA suggested that 20 wt.% SiC reinforcement in 80 wt.% mullite in composite at 430 MPa hydraulic press load and 1400°C sintering temperature resulted in enhanced mechanical properties with porosity, wear, and surface roughness values of 44.80%, 666 µm, and 6.344 µm, respectively. Surface morphology using SEM and XRD/EDS mapping confirmed the presence of wear debris along with the formation of aluminium oxides, cristobalite, and intermetallic dense strengthening phases Al2SiO5, Al4SiO9, and Al6Si2O13, which improve abrasion and thermal resistance. The fabricated composite, with its high porosity, low surface roughness, minimal wear, and high-temperature intermetallic strengthening phases, can be used in journal bearings and thermal protection layers in automobiles and aircrafts.

Scientific Reports, 2025
India's construction sector has made significant contributions to national growth. Heavy machinery is vital to construction. A concrete pump is an essential piece of equipment used for producing, mixing, and pouring concrete. From an execution and maintenance perspective, this equipment is vital. In order to prevent malfunctions when pouring concrete, a better maintenance plan is required for the concrete pump. The example company currently struggles with determining which maintenance tasks should come first, which drives up maintenance costs, reduces machine availability and profitability, and reduces production. The current effort aims to enhance maintenance strategies by utilising several multi-criteria decision-making (MCDM) techniques, such as modified TOPSIS, VIKOR, and PROMETHEE, to identify the most critical reason for failure and enhance concrete pump maintenance decision-making. Three MCDM strategies are then employed to construct the maintenance criticality ranking after the weight of each criterion is calculated using the fuzzy SAW method. Using three MCDM approaches, the best maintenance strategy is determined out of nine likely causes of failure. According to modified TOPSIS, VIKOR, and PROMETHEE rankings, material wear out is the most critical cause of failure, followed by rubber quality, and high pumping strokes are the least critical factor.
Experimental study and numerical simulation of tribological and mechanical properties of mullite and SiC ceramic matrix composite for journal bearing
Prasoon Choudhary, Gurinder Singh Brar, Varun Sharma
Proceedings of the Institution of Mechanical Engineers Part J Journal of Engineering Tribology, 2025
This study presents a detailed analysis of mullite and SiC based ceramic matrix composites in comparison to traditional materials used in journal bearings. The research integrates experimental investigations and numerical simulations to analyze the tribological behavior and mechanical properties of these composites. The experimental analysis evaluates the frictional characteristics, wear resistance, microhardness, and thermal stability of mullite and SiC-based composites under conditions relevant to journal bearing applications, comparing them with traditional materials such as Bronze and Babbitt. Results show that the mullite-SiC composites demonstrate a lower friction coefficient of 0.15 and a wear rate of 0.002 g, significantly outperforming the traditional materials. To further understand the material behavior, computational models using finite element analysis simulated the stress distribution, deformation, and frictional characteristics at the bearing interface under varying operational parameters. It predicted no deformation in mullite-SiC composites after two hours of operation, with minimal deformation of 4.6191 mm observed after three hours. Stress analysis revealed uniform stress distribution across the composite, with a maximum stress of 2.93 MPa. Additionally, microstructural analysis using Scanning Electron Microscopy (SEM) identifies minimal abrasive wear and the absence of severe adhesive wear on the composite's surface. The average surface roughness along the wear surface was measured at 2.35 µm. Ultimately, the research outcomes aim to contribute significantly to the advancement of journal bearing technology, facilitating their application in diverse industrial settings where high performance and reliability are crucial requirements.
On successive recycling of acrylonitrile butadiene styrene- melamine formaldehyde composite for sensing applications
Gulraj Singh, Gurinder S Brar, Rupinder Singh
Journal of Thermoplastic Composite Materials, 2025
In the past three decades, significant studies have been reported on successive recycling (SR) of acrylonitrile butadiene styrene (ABS) thermoplastic-based composites. However, SR of thermosetting polymers such as melamine formaldehyde (MF), bakelite, etc., is still a challenge in commercial terms, mainly due to high energy requirements. This study highlights the effect of SR for selected composition/ proportion of ABS (87.5% by wt.) and MF (12.5% by wt.) as a composite based on the mechanical, rheological, thermal and Fourier transmission infrared spectroscopy (FTIR) analysis. The study revealed that the tensile properties of ABS-MF composite deteriorate with each SR. The peak strength (PS) and modulus of toughness (MoT) (without recycling) were observed as 42.45 MPa and 1.60 MPa, which was reduced to 18.47 MPa and 0.1459 MPa after 03 SR. A continuous rise in melt flow index (MFI) was observed from 10.46 (without recycling) to 11.924 g/(10min) after 03 SR. Differential scanning calorimetry (DSC) analysis of samples supports the thermal stability of ABS-MF recycled composite after 03 SR. The printability of ABS-MF composite was also ensured after SR using the material extrusion (MEX) based 3D printing. FTIR analysis of ABS-MF composite shows a significant rise in transmittance of infrared radiation after SR, making the composite suitable for sensor applications. Further, the results of the impedance analyzer show an enhanced dielectric constant of ABS-MF composite after SR, which is ideal for sensor miniaturization.

Proceedings of the Institution of Mechanical Engineers Part L Journal of Materials Design and Applications, 2025
Several present-day applications require the joining of dissimilar materials by solid-state processes. Aluminum-stainless steel sheet metal joining finds its application in the Automotive industry. In present work, two dissimilar sheet metal workpieces of Aluminium and Stainless Steel were joined with a newly developed Friction Crush Welding (FCW) process. Macro-structure images along with an X-ray diffraction (XRD) pattern were used to investigate the prepared samples, and a hook-like structure was found along with a U-shaped interface and intermetallic phases such as FeAl2, Fe2Al5, FeAl3, Al, and ϒ-Fe. The work aims to develop a novel Finite Element (FE) model based on ABAQUS for FCW of Aluminium-Stainless Steel. The FE model was developed as a three-dimensional, explicit nonlinear model utilizing the Lagrange technique. The developed FE model was validated by comparing the FE model results with experimental temperature data obtained by infrared thermography. The predicted temperature values from the FE model are in excellent agreement with the experimentally measured values. The influence of welding variables, i.e., tool rotational speed (2000, 3000, and 4000 rpm) and welding speed (15, 30, and 45 mm/min), on temperature, was also investigated. It was found that increasing tool rotational speed increases temperature but decreases stress distribution, whereas the correlation between feed rate and temperature was inversely proportional. Results show that the best weld structure was obtained when welding was performed at a welding speed of 30 mm/min and tool rotational speed of 3000 rpm. The developed FE model may be used to predict the temperature and weld structure.

In recent years, the process of joining different materials has received much attention. This article investigates friction crush welding (FCW) of aluminum and magnesium sheet metals through numerical modeling and experimentation. A three-dimensional, explicit nonlinear finite element (FE) model was developed in ABAQUS utilizing the Lagrange technique. The influence of welding parameter impact like rotational speed (2700, 3500, and 5400 r/min) and welding speed (40, 50, and 60 mm/min) is also examined. The FE model was validated using experimental data from infrared thermography. The observed and predicted values of the weld's temperature are in excellent agreement. Field emission scanning electron microscopy was utilized to evaluate the microstructure of welded joints. Intermetallic compounds were identified using X-ray diffraction, and intermetallic phases such as Mg 2 Al 3 and Mg 17 Al 12 were found . Chemical composition is determined by the use of energy dispersive spectroscopy. The optimal welding parameters for the aluminum–magnesium FCW joint and the impact of IC distribution on the mixing of materials in the weld zone were also determined. Results show that the optimal welding condition was obtained when welding was performed at 50 mm/min and a tool rotational speed of 5400 r/min.
