This paper describes investigation into the effect of the inorganic fillers on structural and physical-mechanical properties of polyethylene-based composite coatings produced by thermal spraying. A comparative analysis of the thermal spraying methods was carried out using spray polymers as an example. It was found that the powder particles made of aluminum and an Fe-B alloy, which were added to the polymeric materials, act as artificial crosslinking centers. This resulted in a decreasing grain size and an improvement in the physical and mechanical properties of the coatings. At low fill levels of the polymeric materials (up to 10% by volume), the degree of oxidation of the coating material decreased during spraying. Paper includes a German-language abstract.
