    Ultrasonic Dispersion of Halloysite Nanotubes for Enhanced Mechanical, Thermal, and Morphological Performance of Epoxy Composites

    By Ritesh Dixit, Wg Cdr (Dr) Anil Kumar, Shakun Srivastava, Ashwani Sharma, Kheelraj Pandey

    Abstract: Halloysite nanotube (HNT)-reinforced epoxy nanocomposites were prepared by mixing HNT with bisphenol-A epoxy (LY 556) using ultrasonication, followed by compression molding. HNT contents of 0–5 wt.% were used. The composites were evaluated for tensile strength, flexural strength, Shore D hardness, Izod impact strength, and thermal stability using thermogravimetric analysis (TGA). The fractured tensile surfaces were also examined to understand the failure mechanism and interaction between HNT and the epoxy matrix. …

    Study of Contact Temperature During Polishing of Zinc Plate with Ultrasonic Vibration Using Single Pole Magnetic Abrasive Finishing

    By Gurpreet Singh, Kheelraj Pandey, Ashwani Sharma, Chitra Bajpai, Gaurav Raj Pandey

    Abstract: The present work scrutinizes the impact of ultrasonic vibration on the contact temperature during polishing zinc plates with Single Pole Magnetic Abrasive Finishing (SPMAF). The efficacy and eminence of FMAB finishing are pointedly influenced by heat generation at the interaction point, as raised up temperatures can lead to the deprivation of abrasive elements or the bonding material inside the brush, which leads to the fading its overall effectiveness. The magnetic …

    Experimental Investigation into Surface Roughness of Polished Zinc Plate with Ultrasonic Vibration Using Single Pole Magnetic Abrasive Finishing

    By Puneet Singh, Ashwani Sharma, Kheelraj Pandey, Chitra Bajpai

    Abstract: This research investigates how applying ultrasonic vibrations influences the surface finish quality of zinc plates when using the Single Pole Magnetic Abrasive Finishing (SP-MAF) method. In SP-MAF, magnetic abrasive particles (MAPs)—amalgamation of ferromagnetic and abrasive materials—are guided by a magnetic field to achieve precise surface finishing. Introducing ultrasonic vibration improves the effectiveness of the flexible magnetic abrasive brush (FMAB), which forms as the MAPs align along the magnetic field lines. …

    Thermal Interaction Analysis Between Flexible Magnetic Abrasive Brush and Aluminium Alloy During Single-Pole MAF

    By Chandan Kumar Jha, Kheelraj Pandey, Vineet Srivastava, Ashwani Sharma, Gaurav Raj Pandey

    Abstract: Magnetic Abrasive Finishing (MAF) is a precision surface‐finishing approach that employs magnetic abrasive particles (MAPs) within a managed magnetic field to eliminate micro-level material and enhance surface condition. In the finishing process, the friction created between the workpiece and the flexible magnetic abrasive brush (FMAB) leads to heat accumulation, which may badly affect the surface integrity. This study focuses on investigating the temperature distribution at the FMAB–workpiece interface to decrease …

    Study of pH Behaviour of Slurry on Surface Morphology of Copper Material with Single Pole Magnetic Abrasive Finishing Process

    By Pravin Kumar Singh, Kheelraj Pandey, Anoop Kumar Sood, Ashwani Sharma

    Abstract: The chemical oxidizers—sodium hydroxide, Marshall’s acid salt, and hydrogen peroxide—were effectively employed in the wet polishing of copper using the SPMAF experimental setup. The manuscript explores preparation of slurry used for polishing copper material using single pole magnetic abrasive finishing (SPMAF) framework. The slurry contains distilled water, 1200-grit aluminum oxide abrasives, sodium hydroxide (NaOH), potassium persulfate (K₂S₂O₈), and hydrogen peroxide (H₂O₂), combined in precise amount. Specifically, 100 ml of distilled …
