ABSTRACT
The developing of the composite materials produce a new generations Functionally graded material (FGM) where the materials characteristics are changing linearly depending to the composition materials variations. However, this piece of research presents an attemp to design, manufacturing and multi Ti/TiO2 combined characterization into each functionally graded materials. The supposed in this design is to better the general Ti/TiO2 characteristics. These materials were designed in order to contain a compositional differences or a gradually microstructure within the body in one piece or single material.
Keywords: Composite Materials, Functionally Graded Material, Ti/TiO2.

1. INTRODUCTION
One of the virtually advanced ideas in Japan during the early 1980s which is the Functionally Graded Materials (FGMs), the materials are introduced this new concept in order to improve the adhesion and decrease thermal stresses in metal-ceramic composites materials which have been developed for reusing them in rocket engines [1]. At the same time, the concepts of FGMs have been promoting a wide world researches activities which can apply on metals,

organic and ceramics composites to produce an improvement with superior physical characteristics [2].
Nowadays, the production of FGMs are considered the next step in the development of composite materials. Where the FGMs are comparatively new engineering materials type in which the microstructure and/or composition changes in one specified direction. It is made of constant change in structure and does not have a specific interface. Subsequently, it is generally supposed that these composite structures must have a better resistance for the mechanical and thermal differences [3].
In metallurgy of powder, the technique of producing FGM is by placing the desired powder layer layer after layer, followed by pressing powder and then sintering. During the process of sintering, some mineral powders will interplay to produce a various compounds and chemical phases, which may be varying, depending on spatial location within the functionally graded material [4].
Titanium is applied for fixing the fractures of bones in the devices of spinal fusion, pins, screws and bone-plates. Another advantage for applying titanium in medicine is that the non-magnetic characteristics, so it poses no risk on patients with implants during MRI and exposure to electronical equipment, [5].
Titanium dioxide is also named titania (TiO2
