Abstract: Porous metallic materials have generally an extensive potential for various applications. It is therefore necessary to know the basic properties of these unconventional materials. [..] Read more

Abstract: To develop mutually beneficial relationships in the value network leading to the final success of the network, businesses need to carry out supplier evaluation. This evaluation can be performed by both entities, i.e. [..] Read more

Abstract: Corrosion behavior of ferritic-martensitic steel Eurofer in stagnant liquid PbLi was studied. Eurofer is under consideration to be the structural steel for fusion reactors. [..] Read more

Abstract: The paper contains the second part of the research which compares corrosion and mechanical properties of different zinc coatings. The following methods of zinc coating were applied: galvanic (PN-EN ISO 4042), hot-dip (PN-EN ISO 10684) and lamellar (PN-EN ISO 10683). [..] Read more

Abstract: Determination of corrosion rate by means of electrochemical methods such as polarization resistance is limited to open-circuit conditions. In the case of cathodic protection, a protected object is polarized to protection potential by means of negative total current, the value of which is thus useless for quantifying corrosion rate.

Abstract: The corrosion resistance of the aluminum-based coating deposited on Inconel Alloy 625 by CVD method was investigated. Specimens of 625 Alloy in as-received state and coated were exposed to static liquid lead at 520 °C. [..] Read more

Abstract: Beer is a widely consumed alcoholic beverage throughout the world and global production figures have shown an increase in trend during the last decade. Many failures and corrosion problems encountered in brewery and fermentation process due to corrosivity of fluids which are rather acidic and also contain live microfauna. [..] Read more

Abstract: The construction material during corrosion processes loses its properties, it causes deterioration of functions, loses its usefulness, applicability. One of the important aggressive environments in the building as well as agricultural, chemical and energetic industry is nitrogen, from which nitric acid may be formed. [..] Read more

Abstract: Corrosion of reinforcing steel is one of the main reasons of reinforced concrete structures deterioration, which is caused primarily by chlorides. Electrochemical chloride extraction (ECE) and electrochemical injection of corrosion inhibitor (EICI) are promising techniques eliminating this adverse effect. [..] Read more

Abstract: Steel S235JR is one of the most popular structural material using on welding constructions. The microstructure of this steel consists of two phases: ferrite and perlite. [..] Read more

Abstract: The results of the corrosion resistance of hot-dip galvanized coatings obtained on bolts made of steel grade 23MnB4 have been presented in the paper. The bolts were subjected to various treatments (heat, mechanical and chemical) before application of the zinc coating. [..] Read more

Abstract: Simulation of iron alloy corrosion is widespread used to predict corrosion resistance. The simulation using corrosion chambers or climatic chambers provides reasonable information on corrosion resistance, the corrosion rate however must be compared to real exposition as the corrosion in simulated environment is accelerated compared to real situation. [..] Read more

Abstract: The demand for coatings that can protect the base material from the influence of high temperature corrosion is nowadays increasing. For this reason, new coatings with potential to succeed in aggressive environments of energy, marine, food, etc. [..] Read more

Abstract: Corrosion resistance of coatings deposited using the HP/HVOF (High Pressure/High Velocity Oxygen Fuel) thermal spraying technology requires high coatings density and a good adhesion to the substrate. The majority of thermally sprayed materials meet the requirements for high corrosion resistance in terms of their composition. [..] Read more

Abstract: Cr3C2-NiCr, Cr3C2-CoNiCrAlY, TiMoCN-Ni (experimental coating), Stellite 6, NiCrBSi and Hastelloy C-276 coatings were deposited on substrate material Wr.Nr. 1.4923 (X22) which is in nitrided state used as an effective constructional material for components in power equipment. [..] Read more

Abstract: Corrosion resistant coatings must exhibit high density (low porosity), good adhesion to the substrate and of course low penetration of oxides. This paper deals with corrosion resistance comparison of six corrosion resistant coatings, which are frequently used in power plants. [..] Read more

Abstract: The effect of lignitic humic acid in 0.1 M NaCl at pH 7 on low carbon steel was investigated using potentiodynamic polarization and immersion test. The morphology and elemental composition of the corrosion products were characterized using scanning electron microscopy with energy dispersive spectroscopy. [..] Read more

Abstract: Phase identification of corroded metal objects might be problematic because corrosion products are usually a complex mixture of different phases. Furthermore, some of present phases may be either semi-crystalline or amorphous. [..] Read more

Abstract: It is already known, that porphyrin–bases are offering better protection against steel corrosion than metalloporphyrins due to their ability to form very stable metallic complexes by linking in their inner core the iron contained in different steels. In this respect, 5-(4-carboxy-phenyl)-10,15,20-tris-(4-phenoxy-phenyl)-porphyrin was synthesized by multicomponent Adler-Longo synthesis, using two different aldehydes and pyrrole, characterized to certify the structure and further used for formulating double thin layers in all possible combinations with MnTa2O6.
