Pioneering studies on the additive manufacturing of a cermet heterogeneous material using SiC ceramic fiber were carried out. Unique studies of the damage staging (cratering) and the transition to the destruction of the formed material during high-speed impact created with the help of an electrodynamic mass accelerator have been carried out. It has been shown that the use of ceramic fiber in a metal matrix reduces the impact crater depth by 22% compared to material with ceramic particles. For the first time, the phase composition of the resulting composite was studied using synchrotron radiation. It was shown that, as a result of laser exposure, silicon carbide SiC is dissolved in the titanium matrix with the formation of secondary compounds of the TiC and Ti5Si3C types. It has been established that the use of SiC ceramic fibers leads to their better dissolution, in contrast to the use of SiC ceramic particles, with the formation of secondary phase compounds, and to an increase in mechanical characteristics.

“…Of particular interest is the laser post-treatment of cold-sprayed cermet coatings, which allows for a significantly enhancement of their mechanical and tribological performance due to the in situ synthesis of new hardening phases [28][29][30][31][32]. Baiamonte et al [28] compared heat treatment in furnace and laser treatment of a Ti-WC cold-sprayed coating.…”

Laser processing is an effective post-treatment method for modifying the structure and improving the properties of cold-sprayed coatings. In the present work, the possibility of fabricating a hard and wear-resistant Ti-based cermet coating by cold spray followed by laser remelting was studied. A mixture of titanium and chromium carbide powders in a ratio of 60/40 wt.% was deposited by cold spray onto a titanium alloy substrate, which ensured the formation of a composite coating with a residual chromium carbide content of about 12–13 wt.%. The optimal values of laser beam power (2 kW) and scanning speed (75 mm/s) leading to the qualitative fusion of the coating with the substrate with minimal porosity and absence of defects were revealed. The microstructure and phase composition of as-sprayed and remelted coatings were examined with SEM, EDS and XRD analysis. It was shown that the phase composition of the as-sprayed coating did not change compared to the feedstock mixture, while the remelted coating was transformed into a β-Ti(Cr) solid solution with uniformly distributed nonstoichiometric TiCx particles. Due to the change in microstructure and phase composition, the remelted coating was characterized by an attractive combination of higher microhardness (437 HV0.1) and lower specific wear rate (0.25 × 10−3 mm3/N × m) under dry sliding wear conditions compared to the as-sprayed coating and substrate. Laser remelting of the coating resulted in a change in the dominant wear mechanism from oxidative–abrasive to oxidative–adhesive with delamination.

In this paper, the mechanical behavior of the metal matrix composite under the action of different thermomechanical loading is investigated. The inhomogeneous structure of composites is explicitly considered in the calculations. Isotropic elastoplastic and elastic-brittle constitutive models are used to describe the mechanical response of the aluminum matrix and ceramic particles, respectively. A representative volume of the composite material containing several boron carbide particles located in the microvolume of aluminum alloy 6061T6 is considered. Two structures are created with different volume fractions of ceramic particles. It is found that the strength of the structure with lower volume fraction of particles is higher than the strength of the structure with larger volume fraction. Two types of problems are solved: 1) tension with considering residual stresses, and 2) tension without considering residual stresses. The Duhamel-Neumann relations are used to take into account residual stresses in the calculations. The influence of residual stresses on the fracture of particles in mesovolumes is investigated. Dynamic boundary value problems are solved by the finite element method in the ABAQUS / Explicit software package.
