| Description |
Nanocomposite coatings based on Ti, O, C and H thickness of 70 – 200 microns with hardness of 1015 250 HV0.05 and porosity 2 – 5% were deposited on aluminium samples by using the cumulativedetonation equipment. The nanocomposite coatings were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM) with diffraction, X-ray phase analysis, hardness measurements. It is shown that the area of the coating that adjoins to the substrate contains a transition layer of intermetallic TiAl and the nanocomposite coatings based on Ti, O, C and H are characterized by the presence of titanium nanocrystalline grains with face-centered close-packed lattice, amorphous phases and nanoamorphous oxide of titanium. It was found that the main phases of the composite coatings are Ti, TiO, rutile, anatase, Ti2O3. In the composite coatings formed from the hydrogenated powder was recorded the presence of -TiH phase and TiH2. |
