The production of a Functional Gradient Material by Ordinary P/M Technique

In the technique of producing functional gradient materials, made with different specific layers, a lot of intense investigations were done until now, especially in layers contactiong a surface and the control of interfaces.In our work, we tried to make FGM with a conventional method.The procedure is as follows:(1) fabrication of a porous bulk with a density gradient.(2) filling this bulk with a specific material. In the first step, we try to figure out the possibility of producing such a density gradient porous bulk.
