“…Paint coatings are fundamentals of camouflagethey camouflage vehicles/objects in the optical range, both in visible light (VIS) and in the near-infrared (NIR) range [31]. The main task of effective camouflage is to eliminate those features, which may cause the object to be differentiated from its surroundings [30], i.e. those that make it possible to distinguish one's own assets from the background, and these may include, for example, colour, shape, size, gloss and texture [37,42].…”

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 threelayer 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.

The paper presents an assessment of the effect of artificial aging conditions on the properties of varnish coating systems used for effective masking of military equipment and the service life of this type of coating protections was determined. As part of the research, operational exposures were simulated in the form of: accelerated corrosion tests in an artificial atmosphere in accordance with PN-EN ISO 12944-6, a continuous condensation environment at elevated temperature in accordance with the PN-EN ISO 6270-2 standard and short-term temperature impact up to 250 °C. The evaluation of the properties was carried out on the basis of measurements of the surface geometric structure and adhesion by the peel-off method. On the other hand, measurements of specular gloss, color in the range of 400-700 nm and reflectance in the range of 350-1200 nm were made in relation to the requirements of the Polish Defence Standard NO-80-A200. The operational durability of the paint coatings was assessed in terms of damage in accordance with PN-EN-ISO 4628.

“…Rapid prototyping has a wide range of applications and often involves the application of special coatings [20,21], including DLC [22][23][24] or electrospark deposition [25,26], modification of the morphology of the surface layer [27], or welding joints [28]. The presented article introduces a prototype of a flexible cup for a harmonic drive, which due to its significant possible gear ratios and high precision, can find applications in hydraulic control [29][30][31] and the military sector [32][33][34]. Due to the multidimensional dependencies, the implementation of formal statistical techniques [35][36][37], including expert systems support [38] and nonparametric approaches [39][40][41], is necessary.…”

Abstract. This article presents an analysis of the geometrical accuracy of flexspline prototypes that were a component of harmonic drive. To produce the test models, a MEM (Melting and Extrusion Modeling) method was used. This additive method allows the production of elements with very complicated shapes from various polymeric materials. As the test model, a flexspline made of ABS (acrylonitrile-butadiene-styrene) was assumed. Such a special gear with a complicated construction was chosen, because its unique design allows one to obtain clear conclusions from the analysis. To expand the scope of research, models of flexspline with four different construction solutions were made and tested. As a step of the analysis, contact measurements were performed for several flexspline models on the coordinate measuring machine to check their dimensions. The verification of the geometrical accuracy of flexspline models will allow to assess the usefulness of additive methods for the production of prototypes and finished products.
