“…Composite materials can be divided depending on the production method, intended use, technological properties, and depending on the matrix as well. Metal matrix composites are currently produced with a variety of methods, which include but are not limited to [ 2 , 3 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ]: Liquid matrix technologies (only these will be the subject of this paper because it concerns defects of castings); Deformation technologies, i.e., those that use plastic processing methods; Sinter technologies. …”

This paper presented a new approach to decision making support of defects assessment in metal matrix composites (MMC). It is a continuation of the authors’ papers in terms of a uniform method of casting defects assessment. The idea of this paper was to design an open-access application (follow-up system called Open Atlas of Casting Defects (OACD)) in the area of industry and science. This a new solution makes it possible to quickly identify defect types considering the new classification of casting defects. This classification complements a classical approach by adding a casting defect group called structure defects, which is especially important for metal matrix composites. In the paper, an application structure, and the possibility of its use in casting defects assessment were introduced.

“…При изготовлении каркасного композита TiC (70-80 мас.%) / Ni 3 Al (30-20 мас.%) сначала синтезировали каркас TiC методом СВС, а затем по обычной технологии провели инфильтрацию каркаса расплавом Ni 3 Al при t = 1450÷1550 °С за 40-240 мин без приложения давления [14]. Пористый каркас с однородной структурой и взаимосвязанной пористостью из интерметаллических соединений системы Al-Cr был синтезирован методом СВС с нагревом в микроволновой печи, а затем пропитывался расплавами алюминия и меди по технологии литья под давлением [15]. В приведенных примерах процесс СВС пористых керамических каркасов выполнялся на простом оборудовании за короткое время и с низким энергопотреблением, но это была только первая стадия двухстадийной технологии получения каркасных металлокерамических композитов.…”

The paper reviews the results of using the process of self-propagating high-temperature synthesis (SHS) to obtain high-temperature nickel alloys and composites based on titanium carbide (TiC) and nickel. In order to reduce the brittleness of these composites, it was proposed to replace the TiC ceramic phase by the MAX phase of titanium silicon carbide (Ti3SiC2) and use the SHS process to obtain a Ti3SiC2–Ni skeleton composite. Nickel for Ti3SiC2skeleton infiltration was introduced in three variants: by introducing to the reaction mixture; in the form of a briquette located between two SHS charge briquettes; and similar to the second variant, but with the barrier layers of paper between the Ni and SHS charge briquettes. It was shown that Ni melt in all three variants prevents the formation of the titanium silicon carbide MAX phase thus leading to its degradation. Ni introduction into the reaction mixture according to the first variant made it possible to obtain a homogeneous composite, which became almost non-porous with an increase in Ni concentration up to 50 %. When the Ni briquette was placed between two compacted briquettes of SHS charge, it was possible to melt a relatively small amount of Ni (23–29 % of the mass of synthesized composite samples), which was not enough to completely fill the porous layered skeletons of Ti3SiC2. 20 % of Si added to the Ni briquette increased infiltration depth, lowered the degree of MAX phase degradation at the infiltration point, and formed a more homogeneous composite consisting of a porous skeleton of TiC, TiSi2and Ti3SiC2phases partially filled with metallic nickel during Ni(Si) melt infiltration.

“…This requirement could be met by composites with foam materials, e.g., porous reinforcing particles [9][10][11] and porous particles with Cr [13]. Higher porosity reduces the density of composites and makes it possible to shape tribological properties of contacts where such composites have been used.…”

The paper presents some basic information on manufacturing, structure and selected properties of a new hybrid composite with an aluminium alloy matrix elaborated for automotive applications. A porous oxide ceramics constitute the reinforcing phase of the composite and glassy carbon plays the role of a solid lubricant. The properties of a composite, which contains exclusively a ceramic reinforcing phase and a hybrid composite with porous ceramics and glassy carbon, have been compared. The composite with glassy carbon, obtained by the application of new method, features uniform carbon distribution upon ceramics walls which significantly influences its tribological properties. The friction in air coefficient of a hybrid composite sliding against grey cast iron is 0.12, whereas in the case of a composite containing exclusively ceramics sliding against cast iron it amounts to 0.3.
