Operational tests of coating systems in military technology applications

The paper presents an analysis of the functional operational properties of multilayer coatings for use in military technology in the field of masking. The developed coating systems are characterized by operational innovation due to their small thickness when compared to those currently used by global defence contractors while maintaining the re-emission coefficient required for camouflage to be effective in the optical range. Their service life and durability were assessed in terms of functional properties based on measurements of attenuation coefficients, surface geometric structure, adhesion, specular gloss and colour parameters. The tests were carried out for coating systems fabricated in five variants: a two-layer paint system (SP1), a three layer paint system (SP2), a laser-modified three-layer paint system (SP3) and a four-layer paint system in two variants (SP4 and SP5), with the former being modified with carbon nanotubes and the later - with spherical iron. Coating systems are characterized by low roughness and good adhesion and have appropriate attenuation coefficients for radar waves. Due to their operational properties, the developed coating systems can be used on armaments and military equipment.
