Abstract: Stainless steels are considered to be a perspective candidate as a bipolar plate material for the polymer electrolyte membrane fuel cells. The main reasons for using this material are properties such as low cost, high strength, electrical and heat conductivity and reasonable corrosion resistance. [..] Read more

Abstract: The paper presents research determining the effect of surface preparation on the quality of varnish coatings obtained by electrophorus. The tests were carried out on steel parts used for the construction of trailers and bodies for trucks. [..] Read more

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: 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.

It is established that the developed passivation coatings applied on aluminum alloy parts for corrosion resistance and protective ability are comparable with chromate coatings. [..] Read more

Abstract: The work is devoted to the study of the process of passivation of zinc and its alloys in ecologically safe molybdate-containing solutions in order to replace highly toxic solutions of black chromate passivation.The concentration range of the solution components was determined, in which black coatings are deposited, corresponding to a point of 10 on a ten-point color scale. It was found that the optimal pH values of the solution are in the range from 4.8 to 5.2 units. [..] Read more

Abstract: At present, the research in the field of energy and resource-saving phosphating technologies is being continued, including the processes of applying adhesive and anticorrosive phosphate layers. The phosphating used in the industry is energy-intensive due to the high operating temperatures of the processes, which is necessary to obtain high-quality coatings in a technologically acceptable time.
