The results of the coloristic properties research art items with copper coatings applied by cold gas-dynamic spraying (CGDS), as well color determination technique, allowing to improve approach decoration and restoration items, are presented. This allows us study quantitative decorative surfaces, which largely determines quality aesthetic their subsequent treatment.

We discuss the development of a comprehensive mathematical and numerical model for thin-layer flow of complex liquids on solid surfaces. The model includes physical and surface chemistry effects and allows direct prediction of the flow as it evolves in time, until the liquid has solidified. We pay particular attention to the substrate shape and wetting properties as well as viscosity dependence...

Polyurethanes are the only class of polymers that display thermoplastic, elastomeric, and thermoset behavior depending on their chemical and morphological makeup. In addition to compact polyurethanes, foamed variations in particular are very widespread, and they achieve their targeted properties at very low weights. The simple production of sandwich structures and material composites in a singl...

Metallic and alloyed coatings are used widely in several decorative technology-based applications. In this work, we selected Sn plated on Cu substrates for joining We employed two different plating baths the fabrication of Ni coatings: acidic stannous sulfate Watts bath layer. The current densities were varied from 100–500 mA/cm2. Further, wear friction behavior studied using a ball-on-disc app...

The article presents the results of research on obtaining a modified metal coating surface dielectric materials. study production coatings using chemical method materials is one most important areas research. Currently, there are lot plastic parts in cars, both inside and outside. To meet aesthetic protective requirements, these receive coatings. Metallization used to change characteristics pro...
