    International Journal of Machining and Machinability of Materials, 2024
    In this work, an attempt has been made to alter the surface of Al-7075 substrate using SiC and Cu powder mixed electrodes in Die sink EDM. Experiments have been carried out using Taguchi L-9 orthogonal array. There are three input parameters in this experiment like compaction load, peak current, and tool composition. Analysis of variance (ANOVA) and main effect analysis have also been performed for the output responses like material deposition rate (MDR), tool wear rate (TWR) and surface roughness (SR) respectively. Material deposition rate of 0.385 (mg/min), tool wear rate of 4.37 (mg/min), average surface roughness of 2.101 (μm) and average layer thickness of 25.01 μm have been successfully achieved. Furthermore, examining the nature of surface geology; scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and X-Ray diffraction (XRD) analysis have also been performed which supports the transfer of tool ingredients over work piece samples with enhanced surface characteristics.
  • Experimental investigations and optimization of process variables of electro discharge coating process for Al-7075 alloy: a hybrid MCDM approach
    Lokesh Kr. Ranjan, Sujoy Chakraborty, Uttam Kumar Mandal
    Journal of Adhesion Science and Technology, 2024
    The present study aimed to improve and assess the electrical discharge coating (EDC) factors with aluminium 7075 alloy as a substrate. The results of input variables like current, composition, and compaction load on EDC responses, including material deposition rate (MDR), tool wear rate (TWR), and surface roughness (Ra) were studied. Taguchi’s L9 experiment design was employed with GRA (grey relational analysis), ARAS (Additive Ratio Assessment), and preference value (Ki) was measured. The experiments determined the best parametric setting for more MDR, less TWR, and less Ra. The level of contribution of the process parameters to the response was evaluated by a statistical test known as ANOVA, wherein current appeared as the most noteworthy parameter, followed by composition and compaction load. The results of GRA and ARAS were compared with a prominent MCDM method known as TOPSIS, which substantiated the outcomes of both methods. Successfully attained rates for material deposition, tool wear, and average surface roughness were 0.385 mg/min for material, 4.37 mg/min for tool wear, and 2.101 µm for surface roughness. Finally, a sensitivity study is used to validate the hybrid model’s constancy with a strong correlation. The topography of the deposited surface was analyzed by SEM, wherein base material, deposition, and interface were distinctly visible with the occurrence of a few micro-cracks. The XRD contour of the coating exhibited peaks of Al, Al2Cu, Cu, and SiC. Additionally, the pin-on-disc wear result yielded a substantial drop in the wear of the coated samples as compared to the substrate material.
  • Surface Modification of Al-7075 Alloy by SiC-Cu Ceramic Electrode in Electrical Discharge Coating
    Lokesh Kumar Ranjan, Sujoy Chakraborty, Uttam Kumar Mandal, Siddhartha Kar, Arabinda Meher
    Journal of Scientific and Industrial Research, 2024
    The present study aims to enhance and evaluate Electrical Discharge Coating (EDC) on Al-7075 alloy using SiC-Cu ceramic electrode. The study analyses the impact of input parameters such as current, composition and compaction load on EDC responses, including Material Deposition Rate (MDR), Tool Wear Rate (TWR) and Surface Roughness (SR). Trial tests were performed using Taguchi's L9 experimental design, and thereafter, Grey Relational Analysis (GRA) and technique for order preference by similarity to an ideal solution (TOPSIS) were implemented to optimize all the responses. The experiments were optimized to achieve a higher MDR, lower TWR and lower SR. Analysis of variance was also employed to statistically investigate the experimental data and determine the contribution of each parameter to achieve better results. Optimum condition was achieved with a compaction load of 5 ton, current 6 A and composition 50:50, using both the GRA and TOPSIS methods. At the optimum condition, there was an improvement in GRA from 0.5603 to 0.7778, while TOPSIS showed an improvement from 0.2418 to 0.7659. Further, the morphology of the coated surface was investigated using scanning electron microscopy images and X-ray diffraction analyses, which confirmed the migration of SiC-Cu from the tool materials.

    Journal of Scientific and Industrial Research, 2022
    Composite Materials plays a vital role in the formation of mankind, ranging from the habitation of early civilisation to enable future modernisation. In this present work titania and zirconia reinforced Al6063-Cu composite has been developed by using a new casting process comprising of clay soil and sand mold. On top of that stirrer mechanism has also been used to mix the hybrid abrasive particles of Single Particle Size (SPS), Double Particle Size (DSP) and Triple Particle Size (TPS) in the Al-Cu alloy which is a completely new approach. Taguchi L18 orthogonal arrays have been used in this study to reduce the number of tests. For this present research work, 5%, 7.5% and 10% of hybrid abrasive have been mixed in the alloy to investigate its different properties like elastic modulus, ductility and density. It has been observed that in addition of the reinforcements in the newly developed composites elastic modulus, ductility and density have been improved to 31.42%, 40% and 19.81% respectively. Due to this improved properties this composite can be used to manufacture bearing, valve, aircraft electronics and many other appliances. The experimental results were analyzed by the SN ratio plot and an RSM model was used to predict these properties and to estimate the affecting factors for each property. Further, the RSM models have been corroborated by performing the experiments on the newly manufactured composites for elastic modulus, ductility and density. The result obtained from RSM model shows good similarity with the experimental results.
