Operational tests of coating systems in military technology applications

Abstract

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.

Geometrical Accuracy of Flexspline Prototypes Made by FDM/MEM Methods

“…Such an approach often requires organizational changes [15], the development of new failure mode and effects analysis scenarios [16][17][18], and the implementation of precise measurement and control techniques [19]. 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.…”

Numerical Analysis of a Pneumatic Cushion Operation Safety, including the Airflow Conditions

“…In addition to the primary benefits of increased reliability and safety, it also leads to lower energy consumption [53], thereby increasing the applicability of pneumatic cushion transporters, both as standalone systems and as part of larger devices [54][55][56], posing competition to typical wheeled or conveyor-based transportation [57]. The military has long recognized the advantages of such transportation, especially in the case of air-cushion landing crafts [58][59][60].…”

An Application of the Systematic Diagram in the Failure and Causes Analysis of a Vane Pump

“…These methods allow for the optimization of preventive measures, minimizing them to the necessary minimum in line with lean principles [9,10]. This approach is particularly critical in the production of highly responsible products, such as in the machinery [11,12], railway [13], hydraulic power [14], and military [15][16][17] sectors.…”
