Introduction Functionally graded materials are inhomogeneous composites within which materials properties vary continuously.
This is achieved by gradually changing the composition of the constituent materials, usually in one direction, to obtain smooth variation in material properties [1].
Materials properties are graded in the thickness direction according to a power-law distribution.
The zirconia and titanium alloy are selected for the two constituent materials of the plate in the present examples, referred to as ZrO2/Ti-6Al-4V.

Materials and Methods 2.1.
The functional groups were incorporated to increase the adsorption capacity, to change the pH range for heavy metal adsorption, and to change the adsorption selectivity for the target metal[7] Based on wastes recycling and circular economy, A.niger and other industrial fermentation waste mycelium can be used as a new economic and eco-friendly environmental materials of metal adsorption.
