Effect of Sintering Profile and Composition of Ni/Al<sub>2</sub>O<sub>3</sub> Functional Gradient Materials Coating Layers via Pulsed DC Electrophoretic Deposition
Abstract:functional gradient material (FGM) coating layers with its thickness of 2025 µm were fabricated by pulsed direct current (DC) electrophoretic deposition (EPD). The coarsening effect of Ni was studied to control sintering profile with an intermediate step of 1000°C for 3 h. Controlling the sintering conditions through an intermediate step and varying the number of layers played important roles in reducing cracks on the coating surface. The samples were characterized using X-ray diffraction (XRD), back scattered… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
