Abstract
The paper focuses on the development of a cermet coating production technology using the method of self-propagating high-temperature synthesis (SHS). The relevance of this study is associated with the widespread use of flat electric heaters and protective coatings for various purposes. A method for producing electrically conductive coatings using SHS in Ni + Al and Ti + + Al + C powder mixtures was proposed. The features of the autowave SHS process in Ni + Al and Ti + Al + C powder mixtures were investigated. The mixture was applied to a ceramic substrate in the form of a layer (0.2÷2.0)·10–3 m in thickness through a stencil in the form of a suspension in isopropyl alcohol. The effect of the mixture powder layer thickness on the front propagation velocity and maximum temperature was studied. It was shown that these parameters naturally increase with an increase in the thickness. It was found that the coating based on the Ni + Al mixture consists of NiAl, Ni3Al intermetallic compounds, and the coating based on Ti + Al + C consists of TiC and MAX phases of Ti2AlC, Ti3AlC2. The coating based on intermetallic compounds consists of rounded particles fused together and containing NiAl, Ni3Al phases. Coatings obtained from the Ti + Al + C mixture contain needle crystals of MAX phases and interspersed rounded particles of titanium carbide. The content of the NiAl and Ti2AlC target phases increases with the increasing layer thickness. Coatings based on NiAl, Ni3Al and Ti2AlC, Ti3AlC2 heat-resistant phases (0.2÷1.2)·10–3 m in thickness with a specific electrical resistance of 0.1–0.6 μΩ·m were obtained.
