Abstract

A ceramic, metal, or cermet according to one embodiment includes a first layer having a gradient in composition, microstructure and/or density in an x-y plane oriented parallel to a plane of deposition of the first layer. A ceramic according to another embodiment includes a plurality of layers comprising particles of a non-cubic material, wherein each layer is characterized by the particles of the non-cubic material being aligned in a common direction. Additional products and methods are also disclosed.

First claim

wherein the product is optically transparent.

2. The product as recited in claim 1 , wherein the gradient of the first layer is structurally defined by a first material being arranged in a first predefined pattern and a second material being arranged in a second predefined pattern.

3. The product as recited in claim 2 , wherein at least the first material has a structural characteristic of being deposited through an electrophoretic deposition (EPD) process according to the first predefined pattern.

4. The product as recited in claim 2 , wherein at least the first material has a characteristic of being deposited through an electrophoretic deposition (EPD) process above a non-planar electrode according to the first predefined pattern.

5.
