On the advanced microstructural characterisation of additively manufactured alumina-zirconia based eutectic ceramics:




Additive Manufacturing, Al2O3-based eutectic ceramics


Recently, there have been a number of reports on the fabrication of Alumina-Zirconia (Al2O3- ZrO2 (AZ))-based eutectic ceramics using laser additive manufacturing (AM) techniques owing to the exceptional creep and oxidation resistance coupled with excellent microstructural stability in these materials. Moreover, a number of interesting microstructural features (in these materials) have been reported to be formed by the variation of process parameters (especially, laser scanning speed) associated with the aforementioned AM techniques. The present review provides an overview of the present state of research in the area of laser AM AZ-based eutectic ceramics and highlights the challenges and future outlooks in this avenue of research. In addition, the requirement of employing correlative microstructural characterisation in these materials has been highlighted in the outlooks section.
