“…The use of graded materials as heat barriers in space shutters was considered. Systematic researches over the fabrication of such materials were initiated in 1987 under a research project [22,26], and the Research Society for Functionally Graded Materials publishing the FGM News was set up a year later. An international conference on functionally graded materials, stimulating rapid advancements in materials production, has been regularly held in Sendai, Japan, since 1990 [27].…”

“…With regard to their application, such materials can be divided into, notably, functionally graded materials [22,26], tool gradient materials (TGM) [28][29][30][31][32][33][34][35][36], gradient biomaterials and functionally graded piezoelectric materials (FGPM). Gradient materials, according to the type of combined materials, can be grouped into, particularly [37]: metal material-ceramic material, metal material-metal material, ceramic material-ceramic material, polymer material-ceramic material.…”

This chapter presents essential information concerning sintered tool materials containing carbides, i.e. high-speed steels and metal matrix composites, including sintered carbides and carbide steels. Gradient materials, whose properties change gradually according to their volume, are characterised. The results of investigations are presented in the final part into the structure and properties of newly developed sintered graded tool materials fabricated by the conventional metallurgy method from a mixture of high-speed HS6-5-2 steel powder and WC carbides. Investigations are described for four-layer materials, where the successive transition layers with a smaller and smaller volume fraction of tungsten carbide were constituted from the surface layer side, until a substrate layer containing high-speed HS6-5-2 steel only. The outcomes are described of structural examinations in a scanning and transmission electron microscope, an X-ray microanalysis and the results of density, porosity and hardness examinations of sintered gradient materials and the results of structure and hardness examinations of heat-treated materials.

“…They can be used in many applications ranging from aerospace to chemical industry [5,6]. Several methods have been proposed to obtain gradient distribution of metallic particles in a ceramic matrix, for example slip casting with magnetic field or the powder metallurgical process applied for: Al 2 O 3 /Fe, SiC-AlN/Mo [7,8]. Authors have obtained FGM samples by centrifugal-slip casting which is an innovative, relatively simple and effective shaping method [9].…”

The fabrication and the characterization of Al 2 O 3 /Ni composites with a gradient distribution of the Ni particles are reported. The composites have been obtained by centrifugal-slip casting and subsequent sintering and had the shape of a hollow cylinder. TG/DTA analysis was done for the nickel powder with the addition of the dispersant used in centrifugal-slip casting as well as for the composite green body. The measurements were performed in two atmospheres: argon and the mixture of argon and hydrogen (1:1). Additionally, coupling the thermobalance with the mass spectrometer allowed to determine type of gases released from the samples during thermal treatment. The morphology and chemical composition of the produced composites were analyzed using a scanning electron microscope equipped with an EDS detector. Interface between alumina and nickel was described. Moreover, the X-ray diffraction was made. The stereological analysis confirmed that the nickel particles are distributed in the composite in a gradient way.

“…Thus, the concept of a functional gradient material (FGM) may be suitable for designing and obtaining novel dental implants. A FGM is a composite of two or more phases, where the composition and therefore, the mechanical and physical properties, change gradually over the sample [5].…”
