The nanolayer of titanium carbon groups is partially X-ray amorphous and peaks are not visualized on the X-ray. To prove the presence of carbide groups on the surface of Al, after 10 cycles of chemical assembly, the sample was calcined in a quartz reactor in a protective atmosphere at 700 °C for 3 h, as a result of which a crystalline titanium carbide was obtained on the surface of the substrate, which partially escaped and agglomerated into particles of 10 15 nm in size (Fig.1).

Figure 2 shows a micrograph of Al particles modified by TiC nanostructures, which are the reinforcing phase of the Al@TiC composition. Micrographs and elemental analysis of the reinforcing phase show the presence of titanium, carbon, aluminum, and oxygen in the surface layer.

The presence of a large amount of oxygen may indicate an oxide film that is present on the Al surface. To confirm the presence of TiC in the samples, X-ray photoelectron spectra were taken. Based on the XPS analysis, the formation of titanium carbide TiC on the surface of Al particles was established.
