Micro-texturing has been studied for many decades as a passive antifouling technology. However, most studies have experimental in nature and lack an informed basis the selection of micro-texture architecture. The herein reported preliminary numerical explored micro-textured superhydrophobic superhydrophilic surfaces mitigating biofouling related effects, such Microbial Induced Corrosion (MIC). Surface wettability manipulation is key mitigation strategy these issues. A computational model was...
In this experimental study the green electrical energy generation performance of fabricated triboelectric nanogenerator (TENG) is investigated using a biomaterial based composite. The composite tin oxide (II) (SnO) nanoparticles as fillers on egg shell membrane (ESM). ESM naturally available waste and used substrate for growth SnO chemical bath deposition method. synthesized have spherical morphology with an approximate particle size 80–100 nm. TENG active dielectric layers are different...
The current article presents an advanced analysis of the properties solid-wire electric contacts produced with ultrasonic welding and soldering. Soldering is generally used to join thin, solid copper wires produce electrical in small-volume production, as does not provide acceptable peel force tensile strength due deformation thinning wires. In this article, using a ring before after thermal shock test discussed compared standard soldering technique. was carried out temperature range from...
Purpose The purpose of this paper is to investigate the effect shock waves and strain hardening laser shot peening on precipitation‐hardened aluminium alloy AA 6082‐T651. Design/methodology/approach hardened layer was evaluated by means surface integrity with optical microscopy, scanning electron microscope (SEM), energy dispersive spectroscopy, analysis microhardness residual stress profiles. Corrosion anodic polarization tests in a 3.5 per cent NaCl water solution were carried out express...
The effect of shock waves and strain hardening laser peening without protective coating (LSPwC) on alloy AA 6082-T651 was investigated. Analysis residual stresses confirmed high compression in the near surface layer due to ultrahigh plastic strains rates induced by multiple waves. Corrosion tests a chloride environment were carried out determine resistance localised attack, which also verified SEM/EDS. OCP transients an improved condition, that is, more positive stable potential after LSPwC...
This article presents the study of shock wave propagation through aluminum alloys (pure and 2024-T3) produced by laser plasma using experimental numerical tests. Water confinement regime interaction, pulse duration (7.2 ns), power density (1–5 GW/cm2) range correspond to peening process configuration parameters. To that scope, we simulate non-linear explicit code LS-DYNA, which validate with results. Thereupon, present a descriptive analysis links separately material model loading conditions...
This study investigates the microstructural, mechanical, high-cycle fatigue, and fracture behaviour of a dissimilar 2017A-T451/7075-T651 Al alloy joint produced by single-pass friction stir welding (FSW) without post-processing. Residual stress analysis revealed low tensile residual stresses in longitudinal direction on crown side compressive transverse root weld, indicating an almost zero-stress state. High-cycle fatigue tests showed superior endurance FSWed sample due to synergistic effect...

Friction riveting represents a promising technology for joining similar and/or dissimilar materials of light-weight components. However, the main drawback is that it primarily used only with special machines friction welding have force control. In this study we accessible CNC position A set experiments was performed to establish relationship between processing parameters, rivet formation and its mechanical strength. During manufacturing process, axial torque were constantly measured. The...
