Structure, Phase Composition, and Properties of Ti3AlC2—Nano-Cu Powder Composites Composites based on the MAX-phases are promising materials for various applications. Composites MAX-phase–copper can be used in electrical engineering as wear-resistant and durable sliding contact material. Such composites can be used as coatings on sliding contacts to improve local strength and wear resistance without significantly increasing production costs. In this work, Ti3AlC2—nano-Cu composites with the ratio Ti3AlC2:Cu = 1:1 by weight or approximately 4:1 by volume were studied. The main task of the study is to obtain a dense structure and check the effect of the sintering temperature of the samples on their design, phase composition, mechanical properties, and electrical conductivity. In addition, the sintered specimens were subjected to a hot isostatic pressing to increase the density further. It was found that the best combination of strength, density, and electrical conductivity is achieved after sintering at 1050 °C. A further increase in the sintering temperature leads to an intensification of the MAX phase decomposition process, and at a lower sintering temperature, the copper matrix remains incompletely formed. The Ti3AlC2 MAX-phase has a low density, high modulus of elasticity, high strength at high temperatures, good workability, good oxidation resistance, excellent thermal and electrical conductivity, etc. MAX-phases can also be transformed into MXenes using an etching process. The first explored application of MXenes was in energy storage, which remains a large proportion of MXene activities. MXenes are also promising materials for electromagnetic applications. Thus, MAX-phases can improve mechanical properties by acting on the mechanism of a secondary hardening phase and also affect the electrical properties of the material when using MXenes It is challenging to obtain bulk products from the MAX-phase powders by powder metallurgy methods, in particular, due to the decomposition of the MAX-phase at elevated temperatures. Because the MAX phase has a layered structure, and its high-temperature molding is impossible due to decomposition processes, products from the MAX phase are predominantly porous. One of the promising methods for obtaining dense products based on the MAX phase is the production of metal matrix composites (MMCs). In such composites, the metal acts as a MAX phase binder and fills the pores.
