| Abstract Scope |
This study presents a novel approach for the deposition of aluminium coatings onto Inconel 625 particles using a DC pulse electrophoretic deposition (EPD) technique. The method employs a stable aluminium colloidal suspension synthesized via a straightforward, non-aqueous route without the need for surfactants. To enhance coating adhesion and surface activation, the Inconel 625 particles were pre-treated with ammonium hydroxide. The effects of deposition parameters—particularly coating duration and substrate pre-treatment—on the microstructure and uniformity of the coatings were systematically evaluated. Scanning electron microscopy (SEM) revealed that a 30-minute deposition time yielded a uniform and adherent aluminium layer with improved surface coverage compared to a 10-minute deposition. The coated particles demonstrated promising morphological features for potential application in aerospace-grade 3D printing and high-temperature oxidation-resistant coatings. This work establishes a reproducible and scalable EPD process for aluminium coatings on metal alloy particles, offering an effective pathway for advanced materials engineering. |
