Special Issue Information

Dear Colleagues,

In economic and social terms, corrosion is an extremely important problem for the economy as the losses caused by corrosion in highly developed countries are estimated at the level of 3% -5% of gross domestic product. The physicochemical and electrochemical interaction between metals and their alloys and the surrounding environment leads to the gradual deterioration of the materials until their mechanical and functional properties are completely lost. Economic losses are directly related to the necessity to replace damaged structures, machines, devices, or their components, the use of expensive corrosion-resistant materials, anti-corrosion protection, and also indirectly to production interruptions caused by the need to replace parts or remove damage. The degrading effect of corrosion concerns products made of most materials, but the main group is structures made of steel. The reduction of corrosion losses is influenced not only by the appropriate design of the structure itself, but also by the proper selection, execution, and operation of the anti-corrosion protection. Therefore, corrosion awareness and knowledge of the corrosion mechanism are necessary for the design, selection of materials, and protection systems in order to ensure optimal durability of products under the influence of a corrosive environment.

The scope of this special edition "Corrosion and Anticorrosion of Alloys / Metals" covers research into the latest developments in the wear and corrosive behavior of various materials to understand the corrosion mechanisms of metals and alloys. The topics also include the production of anti-corrosion coatings, their structural characteristics, tests of properties, and physicochemical phenomena occurring during the formation of coatings on various base materials. The main coating technologies include hot-dip galvanizing, thermal spraying, electrogalvanizing, organic coatings, electroless coatings, conversion coatings, as well as PVD and CVD methods, and others. The scope of application of the coatings includes coatings resistant to electrochemical and high-temperature corrosion, as well as coatings for operation in particularly difficult conditions, such as coatings resistant to corrosion in liquid metals.

We invite all researchers interested in corrosion and the design of anti-corrosion systems to present their results related to both experimental and theoretical research.

A significant aspect of corrosion failures and catastrophes originate from trivial mistakes in either the choice or connection of different materials, as well as from inaccurate evaluation of the compatibility between materials and the environment. The example shown in the present paper summarizes several wrong solutions due to a lack of knowledge of the basic rules of corrosion control. By chance, the consequences of these errors already appeared during construction; therefore, they were not able to cause damage during operation. This paper is the third in a series devoted to enhancing the need for professional corrosion control design for infrastructures. Full article

In the hot dip galvanizing process, steel products are immersed in a liquid zinc bath. The contact of steel with liquid zinc causes the corrosion of the steel as a result of Fe dissolution processes in the liquid. If the dissolution process is carried out in a controlled manner, it results in the formation of a coating. Uncontrolled dissolution leads to the degradation of the steel surface. This article presents the results of research into the influence of Bi and Sn additions to zinc baths on the corrosion of steel in liquid zinc. Corrosion tests were carried out under conditions of kinetic dissolution using the rotating disc method. The kinetic dissolution constants of steel with different Si contents in Zn, Zn-0.5Bi and Zn-2Sn baths were determined. It was found that the addition of Bi and Sn lowers the value of the dissolution constant and may act as an inhibitor of Fe dissolution in liquid zinc. Based on the measurements and the determined value of the dissolution constant, the activation energy of kinetic dissolution was determined. It was found that in the temperature range of 440–480 °C, the addition of Bi and Sn increases the value of dissolution activation energy, which reduces the intensity of Fe transfer to the zinc bath.

The present study outlines the first steps in modelling lead corrosion upon contact with an anaerobic HCI solution. These developments, completed with COMSOL Multiphysics, were carried out in dimension 1 of space. This process took place across several stages such that each could be studied and validated. This article presents the governing equations, parameters, and results of these simulations. When lead is immersed in a deaerated HCl solution, its dissolution leads to saturation of the electrolyte with the consequent precipitation of corrosion product. The PbCl2 corrosion product is simulated with a porous domain using either fixed or variable porosity. The results show a PbCl2 development that takes place through growth in space as well as through densification. The simulation highlights the fact that the PbCl2 layer is more compact near the surface of the electrode in accordance with the place of creation of the lead ions. These simulation results are compared with experimental data that validate the first approach. Full article

The article presents the results of the research determining the synergistic effect of Mg and Si additives in the ZnAl23 bath on the microstructure (SEM), growth kinetics, and corrosion resistance of coatings obtained by the batch double hot dip method. On the basis of the research on the chemical composition in micro-regions (EDS) and the research on the phase composition (XRD), the structural components of the coatings with a content of 3 and 6 wt.% Mg and 0.2–0.4 wt.% Si were identified. The corrosion resistance of the coatings was compared with that of the reference coating obtained in the ZnAl23Si0.4 bath in the neutral salt spray test (EN ISO 9227), and the test with sulfur dioxide in a humid atmosphere (EN ISO 6988). The parameters of electrochemical corrosion of the coatings were determined. This allowed for the conclusion that the addition of Mg and Si to the ZnAl23 bath improved the microstructural uniformity of the coating. In the area of the diffusion layer, the presence of the FeAl3 intermetallic phase was found, while in the outer layer the dendrite of the Al-rich solution with interdendritic spaces, where it locates areas of Zn-rich solution, eutectic Zn/MgZn2 or phase separation MgZn2 and Mg2Si are located. Additions of Mg and Si stabilize the kinetics of the coating’s growth, and its course is parabolic. The conducted corrosion tests showed better corrosion resistance of the coatings obtained in the bath with Mg addition compared to the reference coating obtained in the ZnAl23Si bath. The increase in corrosion resistance results from the presence of a more anodic MgZn2 phase, which, however, may be weakened by the presence of Mg2Si phase precipitates. Full article
