“…This is due to the interesting properties of this group of materials, such as high hardness, dissipation of most thermal stresses, and modification of thermal and electric properties [1,2]. Furthermore, the presence of the reinforcing phase can prohibit the crack propagation and improve the fracture toughness of ceramics [3].…”

This paper focuses on a research on the influence of nickel content in zirconia matrix and its impact on the mechanical properties of obtained composites. ZrO 2 /Ni mixed powders were uniaxially pressed and sintered in a nitrogen atmosphere to obtain ZrO 2 /Ni composites that were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and energy-dispersive Xray spectroscopy (EDS). The stereological analysis allows obtaining information about the size distribution of zirconia grains in the sintered composites. Relative density, hardness, fracture toughness, and bending strength were also analyzed. The results revealed that the presence of Ni particles in the composites affects the mechanical properties of the materials. An increased Ni concentration caused a decrease in Vickers hardness and increased the fracture toughness of the ZrO 2 /Ni composites compared to the ZrO 2 samples. This kind of composite is of interest for temperature and flow sensors, thermal barrier coatings for gas turbines and supersonic propulsion systems of spacecrafts, as well as as a material for anode in solid oxide fuel cell.

“…The used materials in powder form were: α-Al 2 O 3 -TM-DAR (Tamei Chemical Corporation Co. Ltd., Japan) with purity of 99.99% and density of 3.96 g/cm 3 and tungsten powder monocrystalline (Sigma Aldrich Co.) with purity of 99.9% and theoretical density of 19.3 g/cm 3 . As organic additives there were used di-ammonium hydrogen citrate (DAC) delivered by POCH SA, with density of 1.48 g/cm 3 and poly(ethyleneimine) (PEI) from Sigma Aldrich Co. with average molecular weight 2000 and density of 1.08 g/cm. Ultra-pure Mili-Q water with conductivity below 9 mS was used a solvent.…”

“…Improved effect depends on used materials, size of ceramic and metal grains, homogeneity of the composite as well as bonding between metal and ceramic grains. Very important are also properties of interphases on interface between metal and ceramic grains [2,3]. There are numerous methods used for fabrication of this kind of materials.…”

Ceramic – metal composites are widely used materials in a whole world. There were invented many fabrication methods for those kind of materials, but still exists some problems which need to be fixed. Stability of high density metal particles (e.g. W, Mo, Nb) in ceramic-metal composite suspensions is one of crucial issues to be solved in order to obtain homogenous composite material with desired properties such as high fracture toughness, mechanical strength, hardness, wear resistance.In this paper, results of two different methods of stabilizing W particles in Al2O3– W – H2O system were compared. The zeta potential by laser doppler electrophoresis, stability by static multiple light scattering and rheological behavior of prepared suspensions were analyzed. As a result application of hetero-flocculation effect was consider as a good way to obtain homogeneous dispersion of metal particles with a high density.

Composites are used for many different products in numerous industries applications. They satisfy the demand for new materials which combine dissimilar materials and represent properties which are not achievable by separate material. Among of them are ceramic matrix composites, especially with metal phase. Different systems have been developing. During the last years the composites with Al 2 O 3 , ZrO 2 ceramic matrix and metals as Ni, Mo, Cu, W, Co have been intensively studied. Metallic particles embedded into ceramic matrix improved mechanical properties such as the toughness, the hardness and the wear resistance. Moreover, other properties as magnetic or electrical of ceramic-metal composites can be significantly changed. Because of that, ceramic-metal composites are considered as structural and functional materials. The final properties of ceramic-metal composites depend on their microstructure, which should be optimize by the design of metal size and distribution into ceramic matrix and selection of the fabrication method. This paper attempts to review the microstructures of ceramic-metal composites based on own experimental results. The following issues will be discussed: design the metal particles distribution into ceramic matrix, opportunities of processing in creating microstructures and fabrication of composites with complex shape and high dimensions, interactions in ceramic/metal interfaces, toughening mechanisms and properties of composites. Keywords: ceramic-metal composite, ceramic matrix composite, microstucture, fabrication of composites, functional materials, metal particles distribution, properties of composites Streszczenie: Z kompozytów wykonywane są elementy wykorzystywane do różnych zastosowań przemysłowych. Wynika to z możliwości uzyskania w nich właściwości nie spełnianych przez pojedynczy materiał. Wśród kompozytów o osnowie ceramicznej intensywne prace prowadzone są nad kompozytami z wprowadzoną faza metaliczną. Do częściej badanych układów zalicza się ceramikę Al 2 O 3 oraz ZrO 2 w połączeniu z metalami
