The development of environmentally friendly materials has been the focus many research groups in recent years due to increased harmful effects plastics on environment. Bio-based are considered a key solution from sustainable manufacturing perspective. nano-coating biopolymer blends with silver nanoparticles is subject challenging projects line EU Directive environment protection and manufacturi...

Plasma generation over large areas using a hollow cathode discharge is described in this study. Radio frequency linear hollow cathodes in several arrangements, for operation at reduced gas pressure and suitable for scale-up, are presented. Examples of surface processing and coating by PVD, both by hollow cathode discharge (HCD) and hollow cathode arc (HCA), are given. A non-equilibrium atmosphe...

Self-organization during friction in complex surface engineered tribosystems is investigated. The probability of self-organization in these complex tribosystems is studied on the basis of the theoretical concepts of irreversible thermodynamics. It is shown that a higher number of interrelated processes within the system result in an increased probability of self-organization. The results of thi...

The increasing demand on high quality optical systems with complex geometries, low tolerances and a low installation space necessitates new replicative production systems for complex optical glass elements. The technology precision blank moulding shows promising properties to comply with these demands on an industrial bulk production. Due to the required high surface quality and low surface rou...

This article analyzes PVD coatings (physical vapor deposition—the coating material is vaporized and deposited by sputtering or arc evaporation, are applied at lower substrate temperatures thus can be to a wider range of substrates) samples which located in fixture. fixture enables additional rotation the sample via process. The allows an increase coated tools one batch, therefore current capaci...

This article discusses the possibilities of two methods for monitoring Physical Vapor Deposition (PVD) process parameters: multi-grid probe, which makes it possible, in particular, to determine energy distribution ions one- or two-component plasma and spectrum analyzer glow discharge electromagnetic radiation signal based on Prony–Fourier multichannel inductive spectral analysis sensor. The cur...

The study evaluated antioxidant status in patients with peripheral vascular disease (PVD), with and without concomitant diabetes mellitus (DM). 211 participants were divided into standardized 4 groups: patients with PVD and DM (PVD+DM+), patients with PVD without DM (PVD+DM-), patients without PVD with DM (PVD-DM+) and patients without PVD and DM (PVD-DM-). The diagnosis of PVD was established ...

This article introduces a continuous, gas-phase method for depositing thin metallic coatings onto (nano)particles using a type of physical vapor deposition (PVD) at ambient pressure and temperature. An aerosol of core particles is mixed with a metal vapor cloud formed by spark ablation by passing the aerosol through the spark zone using a hollow electrode configuration. The mixing process rapid...

Industrial upscaling frequently results in a different coating microstructure than the laboratory prototypes presented literature. Here, we investigate wear behavior of physical vapor deposited (PVD) MoS2 coatings: A dense, nanocrystalline coating, and porous, prismatic-textured coating. Transmission electron microscopy (TEM) investigations before after testing evidence crystallographic reorien...
