Abstract: The electropolymerization of EDOT/PyBA/BRIJ by cyclic voltammetry on stainless steel and glassy carbon was studied in aqueous solution. The protective properties of the resulting coatings on stainless steel were investigated in the aggressive medium of 0.25 mol dm-3 K2SO4 + 0.5 mol dm-3 KCl with pH = 2. [..] Read more

Abstract: One of the methods of protection of metal surfaces from an aggressive environment is the formation of continuous coating on their surfaces with water-repelling properties and a self-cleaning ability, which give the material superhydrophobic properties and also protect them from contamination.A solution for hydrophobization of aluminum alloy 5556 in a solution containing dimethyl sulfoxide and water in a ration of 7:1 and also stearic acid in the amount of 0.01 mol/L was developed.It was determined that the newly-formed coating in this solution is characterized by a contact angle of θс = 151°. The protective ability of coatings determined by the drop method as the time until the appearance of corrosion product under the drop of Akimov solution amounts to 125 s.Corrosion tests of AA 5556 speciments with hydrophobized surface were conducted (ASTM B117) in a salt fog chamber in the developed solution.

Abstract: The influence of the nature of organic additives on the rate of low-temperature chemical deposition of nickel is studied. The class of organic compounds allowing to obtain adhesion coating of chemical nickel was revealed. [..] Read more

Abstract: Geo-components are manufactured from steel, galvanized steel and polymers commonly take the form of reinforcing meshes, straps or strips for high quality erosion and sediment control systems. Prediction of durability of zinc/zinc alloyed coatings can be done on the basis of knowledge of their thickness and zinc/zinc alloyed corrosion rate in soil. [..] Read more

Abstract: Magnesium and its alloys are considered for specific applications in medicine such as fixation devices, screws and stents. However, release of hydrogen gas, pH increase and premature failure of the mechanical integrity of implant material are considered as the main limitations. [..] Read more

Abstract: The thermal spraying of metallic coating (zinc, Zn-Al15, etc.) from wire is suitable technique for surface treatment corrosion protection of large structures. This study was carried out to investigate and evaluate the properties of zinc coatings affected by spraying techniques - heated by electrical arc or flame. [..] Read more

Abstract: Electrochemical noise analysis (ENA) was used for the evaluation of corrosion protective properties of patina rust layer formed on weathering steel S355J23W after 8 years of exposure test in Berlin atmosphere. Electrochemical parameters derived from shot noise theory were obtained and related with changes or degradation in tested rust film during 456 h exposure in SO42- and Cl- containing aqueous solution.

Abstract: In recent years, nano-sized cerium and silicon-containing coatings have been increasingly used as alternatives to chromate layers on galvanized steel. The present work is devoted to the development of the technology for obtaining these coatings. [..] Read more

Abstract: Bioactive coatings can be divided into two main groups - organic and inorganic coatings. Hydroxyapatite (HA) is well known as one of inorganic part of mammal’s bone structure and is highly recommended for use in implantology. [..] Read more

Abstract: In this study, the impact of corrosion in S400 grade of reinforcing steel bar as for the mechanical performance on seismic loads (low-cycle fatigue LCF) was investigated. The mechanical performance and life expectancy of S400 grade of reinforcing steel bar on seismic loads was evaluated based on the strength degradation (reduction of maximum strength) during its loading time period, under corrosion or not circumstances.
