Article Synopsis
- - We investigated the creation of functionally graded ceramics made from AlO-CeO-stabilized-ZrO (CTZ) using spark plasma sintering, resulting in a composition and porosity gradient along the axial direction.
- - The gradient was achieved by layering powders with varying AlO to CTZ ratios and using a specialized tool configuration that created a temperature difference during sintering, leading to distinct porosity characteristics in the samples.
- - Testing revealed that the ASY samples exhibited a significant increase in microhardness (up to 10 GPa difference between sides) and higher flexural strength compared to standard samples, attributed to reduced porosity and the formation of elongated CeAlO particles.
