Spark plasma sintering of zirconia/nano-nickel composites Carlos F. Gutierrez-Gonzalez, Nestor W. Solis Pinargote, Said Agouram,Pavel Y. Peretyagin, Sonia Lopez-Esteban and Ramon Torrecillas Abstract This work describes a whole processing route for obtaining dense and nanostructured zirconia-nickel composites with low contents of metallic phase (1–3.5 vol%). For the processing route, a combinationof spray-freezing and lyophilization has… Continue reading Spark plasma sintering of zirconia/nano-nickel composites
