Ceramic Transactions Functionally Gradient Materials

Various approaches based on the bulk particulate processing preform processing layer processing and melt.

Ceramic transactions functionally gradient materials.

Enables obtaining materials with composition and structure gradients having unprecedented properties. Koizumi the concept of fgm ceramic transactions functionally gradient materials vol. 1 introduction functionally gradient material fgm is a novel concept for the realization of innovative properties and or functions that can not be achieved by con ventional homogeneous materials 2 in its simplest structure it consists of one material on one side a second material on the. Has been cited by the following article.

It can be formed by varying chemical composition microstructure or design attributes. The bending strength of the fgm al 2 o 3 tic composites was not much less than that of the. In materials science functionally graded materials fgms may be characterized by the variation in composition and structure gradually over volume resulting in corresponding changes in the properties of the material the materials can be designed for specific function and applications. In this paper selected results of works carried out by the authors and relating to the application of the developed metal ceramic composites were presented in order to manufacture functionally graded materials for target purposes.

Functionally graded material fgm is a material with engineered gradients of composition structure and or specific properties aiming to become superior over homogeneous material composed of same. It is the recent development in traditional composite materials which retains their strengths and eliminates their weaknesses.

Components of various ceramic materials with predetermined material gradients have been reported in recent studies 16 17. A tape casting process was used to prepare various al 2 o 3 tic green tapes from which laminated and functionally gradient al 2 o 3 tic materials fgm al 2 o 3 tic were produced by cutting stacking and laminating the material removing the binder and hot pressing the green bodies. Developed an extrusion method to control the fabricate caco 3 composite with a graded color. The optimum material gradient of a rectangular plate made of functionally graded material fgm is determined in this study.

A green part with graded composition of alumina al 2 o 3 and zirconia zro 2 was also fabricated.
