Abstract:
The purpose of the work was to assess the influence of the vibro-abrasive treatment on the quality of the zinc coating. The use of vibro-abrasive finishing in the production process of fittings for overhead power line is designed to improve the aesthetics of the coating by eliminating zinc beads and burrs, as well as shorten the time of detecting the details on the production.

Abstract:
The electrochemical anodization of titanium has received a lot of attention in recent years, especially for its application for biomedical purposes, offering a biocompatible titanium oxide with architecture of a large energy surface, and highly controllable nanoscale characteristics.In this work, TiO2 layers were synthesized on a well-polished titanium surface, by the anodizing technique, under a voltage of 20 V, for 15, 30 and 45 minutes respectively, using as specific electrolyte: 1M CH3COOH /1M Na2SO4/0.5 Wt% NaF.Interfacial integrity and variation of elemental composition along the interface were studied by scanning electron microscopy (SEM), equipped with an energy dispersive X-ray analyzer (EDX). Electrochemical behaviour was studied both by measuring the evolution of open circuit potential (OCP), by electrochemical impedance spectroscopy (EIS), and by linear polarization (LP) in Hank's solution as a physiological environment.

Abstract:
The paper offers an analysis of the fluoride conversion coating prepared on ZE10 magnesium alloy with the aim to improve material corrosion properties with respect to the biocompatibility of the alloy. The coating was prepared via unconventional process, by immersion of the alloy in Na[BF4] molten salt at 430 and 450 °C for various treatment times. [..]

Abstract:
The study of the geometric characteristics of the metal sheet surface with textured polymer coatings is justified by their connection with mechanical and optical properties. Studying of the surface of coated samples using optical microscopy revealed that it consists of grooves that are assembled into star-shaped clusters scattered across the entire surface of the sheet.

Abstract:
The technology of preparation and subsequent use of nanoparticles is currently a very actual topic, because these particles may have different properties opposite to the conventional materials from which these particles are produced. This article is focused on the production and application of titanium dioxide nanoparticles produced using different methods and their application to the PTFE matrix to create the functional composite coating.

Abstract:
Metal products with ttextured polymer coatings are distinguished by high strength, durability and esthetic qualities, which give to building structures (roof, etc.) a natural and noble appearance. At modern metallurgical enterprises, the correspondence of the color and texture of the polymer coating with the required parameters (color difference, gloss, etc.) is estimated often visually (“by eye”), without the use of magnifying devices.

Abstract:
Sputter-deposited Zr/Nb nanometric multilayer films with a periodicity (L) in the range from 6 to 167 nm were subjected to carbon, silicon and copper ion irradiation with low and high fluences at room temperature. The ion profiles, mechanical proprieties, and disordering behavior have been investigated by using a variety of experimental techniques (Secondary Ion Mass Spectrometry - SIMS, nanoindentation, X-ray diffraction - XRD, and scanning transmission electron microscopy - STEM).
