A lightweight, highly corrosive resistant, and high-strength wrought alloy in the aluminum family is the Aluminium 8006 alloy. The AA8006 alloy can be formed, welded, and adhesively bonded. However, the recommended welding methods such as laser, TIG (Tungsten Inert Gas welding), and ultrasonic are more costly. This investigation aims to reduce the cost of welding without compromising joint quality by means of friction stir welding. The aluminum alloy-friendly reinforcement agent zirconia is utilized as particles during the weld to improve the performance of the newly identified material AA8006 alloy in friction stir welding (FSW). The objectives of this research are to identify the level of process parameters for the friction stir welding of AA8006 to reduce the variability by the trial-and-error experimental method, thereby reducing the number of samples needing to be characterized to optimize the process parameters. To enhance the quality of the weld, the friction stir processing concept will be adapted with zirconia reinforcement during welding. The friction stir-processed samples were investigated regarding their mechanical properties such as tensile strength and Vickers microhardness. The welded samples were included in the corrosion testing to ensure that no foreign corrosive elements were included during the welding. The quality of the weld was investigated in terms of its surface morphology, including aspects such as the dispersion of reinforced particles on the welded area, the incorporation of foreign elements during the weld, micro defects or damage, and other notable changes through scanning electron microscopy analysis. The process of 3D profilometry was employed to perform optical microscopy investigation on the specimens inspected to ensure their surface quality and finish. Based on the outcomes, the optimal process parameters are suggested. Future directions for further investigation are highlighted.

This study examined the effects of a minimum quantity lubrication (MQL) and a Cupric oxide- (CuO-) based nanofluid on Inconel 718 machinability. Additionally, by using an MQL CuO-based nanofluid during the turning process, Inconel 718’s tribological characteristics are optimised. The experimentation was done using the minimum quantity lubrication (MQL) method. With the aid of magnetic stirring and an ultrasonic bath process, CuO nanoparticles were dispersed in distilled water, sunflower oil, and soyabean oil to create nanofluid. Soyabean oil contains uniformly distributed CuO nanoparticles. All the experimental trials are designed based on the L18 Taguchi-based orthogonal arrays and performed on CNC turning under MQL and nanofluid environment. There are four input parameters that were selected at mixed level, namely, cutting speed, feed rate, weight % of CuO in the nanofluid, and flow rate to analyze surface roughness and tool wear. In addition to that, the response surface method was used to identify the optimum condition for better surface roughness and tool wear. Surface roughness and tool wear were measured using the surface roughness tester and toolmaker’s microscope, respectively. Experimental results observed that cutting speed and weight % highly affect surface roughness whereas cutting speed and flow rate affect tool wear. The predicted optimal values for lower surface roughness are 160 ml/hr flow rate, 92.99 m/min cutting speed, 3 weight % of CuO, and 0.1 mm/min feed rate and for low tool wear 80 ml/hr flow rate, 92.99 m/min cutting speed, 3 weight % of CuO, and 0.1 mm/min feed rate.

Now a day’s many companies manufacturing the most advanced submersible pumps with Acrylonitrile Butadiene Styrene (ABS) based polymer, which is available in the market for use in domestic, commercial and even research activities. ABS based pumps are widely used in mining, construction and chemical industries. Acrylonitrile Butadiene Styrenehasmuch application in the temperature range from -20 to 80°C. The ABS based polymer composites are used in submergible pumps due their important properties such as corrosion resistance, light weight, erosion resistance, etc. In the current work, the technique used for the fabrication of GFRP- ABS laminateis compression molding, as per the ASTM standard. The various tests are conducted as per Design of Experiments. Analysis of experimental data was performed using Minitab software and tests were conducted for Flexural strength, Inter Laminar Shear Stress, Tensile strength. Three factors areconsidered for the Design of Experiments namely, fibre-to-resin ratio, fibre orientation and period of immersion in artificial sea water. The outcomepoints towards Flexural strength; ILSS and Tensile Strength areat highest along 40:60 fibre-to-resin ratio with 0°/90°fiber orientation, longer the contact to sea water more is the fall in the strength of the composite material and also due to sea water diffusing into the composite material specimen, there is an increase in its weight.

The microstructure, mechanical characteristics, and tensile fractography of Al2014 alloy reinforced composites with 5 and 10% wt. % of 150 to 160 micron-sized SiC particles were investigated in this study. The melt stir process was used to make composites comprising 5 and 10% SiC particles in the Al2014 alloy. To increase the wettability between Al matrix SiC particles, SiC particles were warmed to 300 degrees Celsius before being disseminated into the Al2014 alloy matrix in two phases. SEM, EDS, and XRD were used to examine the specimens micro-structurally. ASTM standards were used to evaluate the mechanical characteristics of micro SiC particles reinforced Al alloy composites with a content of 5 to 10%. SEM and EDS microstructural tests revealed the existence and dissemination of micro SiC particles in the Al2014 matrix. The addition of 5 and 10% weight % of micro SiC particles to Al2014 alloy improved its hardness, ultimate, yield, and compression strength. With the addition of 10 wt. % of SiC, the hardness, ultimate strength, yield strength, and compression strength of Al2014 alloy improved to 15.96%, 35.2%, 43.8%, and 38.7%, respectively. Furthermore, the presence of SiC particles reduced the ductility of Al2014 alloy. SEM microphotographs were used to examine the manufactured Al2014 with SiC composites for tensile fracture analysis, revealing the various mechanisms intricate in tensile fracture.
