One of the promising ways to increase the mechanical, thermophysical properties of thin coatings is to reinforce them with nanosized 2D elements, in particular, carbon nanostructures. At the same time, the implementation of such a technological technique, as a rule, involves complex, sequentially conducted operations, and the development of methods for vacuum synthesis of such heterogeneous structures carried out in a single technological cycle with the possibility of controlling the degree of reinforcement, morphology, and phase composition is relevant.

The purpose of the development is to establish the features of the formation from the gas phase generated by laser dispersion of a composite target, iron-containing oxide coatings reinforced with carbon nanostructures during their deposition, to determine the influence of process conditions and modes, heat treatment on the morphology and phase composition of nanostructured layers. It has been established that when a mixture of polyethylene with iron oxalate is used as a target as a result of its laser dispersion, finely dispersed layers containing carbon nanostructures are formed on the substrate. At the same time, with an increase in the content of iron oxalate in the target and heat treatment of the coating, the grain size increases. It is shown that the carbon structures formed in the oxide matrix are contained mainly in the form of planar-spaced nanotubes, the smallest of which is manifested in layers deposited by dispersing a mixture of polyethylene and iron oxalate with a mass ratio of 1:2.

The research results determine the high promise of using the proposed approach in the formation of thin coatings reinforced with carbon nanostructures in order to increase their mechanical properties. The main technological methods for changing their structure and phase composition are determined.
