Data showing the effects of vibratory disc milling time on the microstructural characteristics of Coconut Shell Nanoparticles (CS-NPs)

Abstract

Coconut Shell (CS) as agricultural lignocellulosic biomaterial and agro-waste is predominantly available in India, Malaysia, Nigeria, Thailand, Sri Lanka, and Indonesia. It has proven to have effective durability characteristic, good abstractive resistance, high toughness, and good adsorption properties, and is most suitable for long standing use in many applications such as reinforcement, source of energy, fillers as well as activated carbon and its performance, efficiency and effectiveness depend wholly on whether is in form of nano-, micro-, and macro- particles. In this data, effects of milling time on morphological characteristics was experimented using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and X-Ray Fluorescence (XRF) analyses. The SEM images were taken at magnifications of 1.00kx, 2.00kx and 5.00kx which gives respective 50 µm, 20 µm and 10 µm in different milling time of 0, 20, 40 and 60 mins. Digital Vibratory Disc Milling Machine (VDMM) rated 380 V/50 Hz at 940 rpm was employed for the grinding and the morphology of the milled nanoparticles were characterised. It was revealed from the data collected that 0 min (i.e. 75 µm sieved) has the highest mean area value of 16.105 µm2 and area standard deviation of 200.738 µm2 with least value of a number of particle size distribution of 809 µm. In contrast, 60 mins milled has the lowest values for mean area and area standard deviation of 8.945 µm2 and 115.851 µm2 respectively with the highest number of particle size distribution of 2032 µm. It was observed that milling time increases the number of particle sizes distributions and reduces the area of particle size.

Corrosion study and quantitative measurement of crystallite size of high strength aluminum hybrid composite developed via friction stir processing

“…The morphological and elemental attributes of the titanium alloy powder used which was purchased in of 45 μm–90 μm average sizes from TLS Technik GmbH & Co was carried out using TESCAN VEGA 3 LMH scanning electron microscopy that is equipped with energy dispersive x‐ray spectrometer (EDXS) operated by Oxford software while the developed coconut shell ash was also characterized after milling into near nano‐particles . The scanning electron microscopy images with an accelerating voltage of 20 kV, a beam intensity of 10 and a working distance of 15.01 mm to 16.22 mm between the specimen and the detector were used.…”

Experimental data on surface roughness and force feedback analysis in friction stir processed AA7075 – T651 aluminium metal composites

“…The Data presented are from the characterization of friction stir processed of Aluminium Alloy 7075-T651 with different reinforcement agro-waste powders such as coal fly ash (CFA), wood fly ash (WFA) [1], cow bone ash (CBA) [2], coconut shell ash (CSA) [3], palm kernel shell ash (PKSA) [4]; and metallic powders such as stainless steel alloy powder (17-4Ph) and titanium alloy powder (Ti-6Al-2Sn-2Zr-2Mo-2Cr-0.25 Si). The agro-waste powders were firstly milled into nanoparticle individually and then pour inside pure graphite crucible and heat treated in a muffle furnace set at 500 °C for 1 hour and then cooled inside the furnace to room temperature before applying it on the substrate for processing.…”

Influence of carbonaceous agrowastes nanoparticles on physical and Mechanical properties of friction stir processed AA7075-T651 metal matrix composites

“…In this data analysis, the base material used for experimental data acquisition was Aluminium Alloy AA7075-T651 of dimensions 300×125×6 mm 3 with a chemical compositions of Al (88.93%), Zn (5.92%), Si (0.05%), Fe (0.15%), Cu (1.93%), Mn (0.01%), Cr (0.193%), Ti (0.02%) and Mg (2.8%) and its mechanical properties as received are shear strength (330 MPa), Brinell Hardness (150), Fatigue strength (160 Mpa), Poisson's Ratio (0.32), Shear Modulus (26 GPa) while Elastic Modulus, Ultimate tensile strength (UTS) and Yield Strength are 70 GPa, 570 MPa, and 500 MPa respectively. The materials used for the reinforcement during the FSP are wood fly ash nanoparticle (WFA-NPs) [41], coal fly ash nanoparticle (CFA-NPs) [29, 42], cow bone ash nanoparticles (CBA-NPs) [43], Coconut shell Ash Nanoparticles (CSA-NPs) [44,45] and palm kernel shell ash nanoparticles (PKSA-NPs) [46]. All the powders undergone carbonization and calcination process before using them as reinforcement during FSP process, this is to induce thermal stability, phase transition, thermal decomposition as well as removal of a volatile fraction from the material before using.…”
