Structure and Properties of Nanocomposite Coatings Based on Titanium, Oxygen, Carbon and Hydrogen Obtained by the Cumulative-Detonation Device

摘要

Nanocomposite coatings based on Ti, O, C and H thickness of 70 – 200 microns with hardness ofud1015 250 HV0.05 and porosity 2 – 5% were deposited on aluminium samples by using the cumulativedetonationudequipment. The nanocomposite coatings were examined by scanning electron microscopyud(SEM), transmission electron microscopy (TEM) with diffraction, X-ray phase analysis, hardness measurements.udIt is shown that the area of the coating that adjoins to the substrate contains a transition layerudof intermetallic TiAl and the nanocomposite coatings based on Ti, O, C and H are characterized by theudpresence of titanium nanocrystalline grains with face-centered close-packed lattice, amorphous phases andudnanoamorphous oxide of titanium. It was found that the main phases of the composite coatings are Ti, TiO,udrutile, anatase, Ti2O3. In the composite coatings formed from the hydrogenated powder was recorded theudpresence of -TiH phase and TiH2.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/34889
