“…Recent years, researchers attempted to prepare Ti 3 SiC 2 based composites by adding an enhanced phase. Benamor et al [7] investigated the effect of adding enhanced phases or solid lubricants on the high temperature tribological behavior of Ti 3 SiC 2 and they improved the tribological property by optimizing the composition and preparation process. The sintering processes and the related sintering mechanisms of the Ti 3 SiC 2 based composites were widely studied [8][9][10][11][12][13][14].…”

The influence of sintering parameters on the microstructure, phase composition and mechanical property of the Ti3SiC2/Cu composites sintered by spark plasma sintering technique was investigated and the related sintering mechanism was clarified in detail. Results indicated that during the heating process, one part of the high energy adsorbed by the composites let Cu melt and fill the gaps inside the composites. Meanwhile, there’s different molten condition about Cu duel to different heating temperature that cause Cu fill in the most space between Ti3SiC2 particles. The other part of the energy caused to the local high temperature, contributing for the chemical reaction and the formation of TiCx and Cu3Si. Therefore, at the same heating rate, the composites showed better mechanical property and higher density with a longer heating time. The heating stage played an important role in the change of the mechanical property, microstructure and volume of the composites. During the holding stage, because the amount of the reactants significantly decreased, the related chemical reaction got slow and the energy needed during this stage was lower than that during the heating stage. And the particle of Ti3SiC2 need more time for moving to the space of Cu. Therefore, the higher the holding temperature, the more significant was the diffusion of the phases. The more uniform the phases, the higher was the density. When heating temperature(higher than hoding tempreture) cause Cu complete melt and holding temperature keep the Cu in semi-melt，there will be a more effective sintering method.

“…As metals, they have good electrical and thermal conductivity, high plasticity, good machinability and excellent thermal shock resistance. As ceramics, they have low density, high stiffness, high melting points, and good resistance to oxidation and corrosion [1][2][3]. Such exceptional properties result from the coexistence of strong covalent ionic MX bonds and weak metallic MA bonds within a layered hexagonal structure (space group P63/mmc) of MAX materials, which are created by repeating a three-layer structure (consisting of two Mn + 1xN layers intercalated by a single atomic layer A) [4].…”

Structural Features and Tribological Properties of Detonation Gun Sprayed Ti–Si–C Coating

et al. 2021

The paper considers the research results of structural-phase state and tribological characteristics of detonation coatings based on Ti–Si–C, obtained at different filling volumes of the explosive gas mixture barrel of a detonation gun. The results analysis indicates that the phase composition and properties of detonation coatings strongly depend on the technological parameters of spraying. With an increase of the explosive mixture in the filling volume of the detonation barrel up to 70% of the coatings consist mainly of the TiC phase, because high temperature leads to a strong decomposition of Ti3SiC2 powders. Thus, the XRD results confirm that at 70% of the explosive gas mixture’s filling volume, partial decomposition and disintegration of the powders occurs after detonation spraying. We established that detonation coatings based on titanium carbosilicide obtained at the explosive gas mixture’s filling volume at 60% are characterized by high wear resistance and adhesive strength. Thermal annealing was performed after spraying in the temperature range of 700–900 °C for 1 h to reduce microstructural defects and improve the Ti–Si–C coating characteristics. As a result of the heat treatment in the Ti–Si–C system at 800 °C, we observed that an increase in the volume fraction of the Ti3SiC2 and TiO2 phases led to a 2-fold increase in microhardness. This means that the after-heat-treatment can provide a sufficient reaction time for the incomplete reaction of the Ti–Si–C (TSC) coating during the detonation gun spraying. Thus, annealing can provide an equal distribution of elements in the coatings.

“…Among them, a phase called the ternary silicocarbide Ti 3 SiC 2 , which later became the prototype of the whole kind and is the most studied to date, is of particular interest [6,7]. However, getting the coatings based on Ti 3 SiC 2 by the detonation method is usually accompanied by the formation of Ti-C and Ti-Si phases [8,9]. The short reaction time of powder mixtures and the decomposition of Ti-Si-C at high temperatures are the main problems for the clearance of phase [10].…”

Effect of Pulsed-Plasma Treatment on the Structural-Phase Composition and Tribological Properties of Detonation Coatings Based on Ti–Si–C

et al. 2021

View full text Add to dashboard Cite

The structural-phase state and tribological characteristics of detonation coatings based on Ti–Si–C before and after pulsed-plasma exposure have been experimentally investigated. The authors of the research used a detonation set-up of CCDS2000 to obtain coatings. The modification of coating surfaces was carried out by a pulsed-plasma flow using the “Impulse-6” installation. The results of the research have shown that the modification of coatings surface by a pulsed-plasma effect causes an increase in the microhardness of the surface layer and in its wear resistance. It was determined that after such type of treatment, there is an increase in the content of the Ti3SiC2 phase. According to the results of XRD analysis, the improvement in the mechano-tribological properties of detonation spraying coatings of the Ti–Si–C system as a result of pulsed-plasma treatment is associated with an increase in the content of Ti3SiC2 phases in the coatings, as well as the formation of carbide and oxide phases on the surface layer.
