Abstract: The production of iron in blast furnaces involves a number of entirely different processes such as: chemical, mechanical, and physical. The input materials often contain several negative elements, such as heavy metals. [..] Read more

Abstract: The content of the paper is a brief description of the basic characteristics of the reactive diffusion in the dissolution of solid copper in the melt of tin solder. Furthermore, it deals with the theory of growth kinetics of intermetallic phases during heat treatment, and a description of lead-free solders and related problems during soldering. [..] Read more

Abstract: Slags formed during pyrometallurgical extraction of zinc and lead contain numerous metals, and can provide a valuable source of these. Metal recovery from Zn-Pb slags can be accomplished using a pyrometallurgical method consisting in recovering materials at sufficiently high temperatures by transferring them to specific condensed phases (including metallic alloys) or the gas phase with subsequent condensation.

Abstract: Austenitic stainless steel with higher chromium and nickel contain are often used as popular material in the energetics, chemical, food processing and medical applications. That material has a suitable combination of strength and corrosion properties for a given purpose. [..] Read more

Abstract: Early steel bars corrosion in reinforced concrete elements are difficult to detect because of the lack of visible changes on the concrete surface. To assess reinforcement corrosion risk level without structure damage some non-destructive diagnostic methods are applied. [..] Read more

Abstract: For cooling tubes manufactured of aluminized carbon steel with inner surface welded longitudinally the question arises if the anticorrosion quality of Al coating produced on external surface can be influenced by the presence of the weld area on internal surface. In fact this quality is related to Al coating ability to prevent or at least to inhibit the corrosion process occurring during penetration of coating by water environment to the steel-coating interface.

Abstract: This paper tries to determine the possibilities of application of the high temperature oxidation of cast iron as a way of surface preparation before hot-dip zinc galvanizing and presents also results of corrosion resistance tests of zinc coatings created after high temperature oxidation of grey cast iron (with flake graphite). Research was focused on elements of overhead power lines - the jaw-chuck (screw-bow). [..] Read more

Abstract: The National Action Plan for the Development of Nuclear Energy in the Czech Republic envisages the preparation for the construction of two new blocks of the nuclear power plant in the location of Dukovany and the location of Temelín. Although the final supplier of these units is not clear yet, there are good prospects that some components could be produced by the local producers. [..] Read more

Abstract: The generally applied requirements on lowering of emission production in the field of power industry have led, among others, into the application of low-emission combustion process of coal fired power plants. Besides the emissions reduction, this process has led to an increase of boilers parts corrosion degradation due to the reducing atmosphere in low-emission boilers, responsible for sulphide corrosion and molten salt attack.

Abstract: The martensitic stainless steel AISI 410 was subjected to plasma nitriding at an increased temperature of 550 °C, 24 h in 3H2:1N2 (l/h) nitriding gas ratio and compared to untreated one. The microstructure and microhardness of the untreated and nitrided stainless steel were evaluated. [..] Read more

Abstract: Electrochemical chloride extraction from a reinforced concrete structure may be accompanied by an electrochemical injection of healing agents if such agents are positively charged and are able to migrate towards the activated reinforcement. Nanoparticles carrying a positive or cathionic corrosion inhibitors might be the proper choice. [..] Read more

Abstract: In this study, special ceramic coatings were prepared on low carbon steel (1.0060 – EN 10027-2) via the plasma spraying technique using a WSP®-H plasma generator with output of up to 40 kg/h of aluminum oxide. Corundum coatings were deposited directly on the surface of steel plungers equipped with an anti-corrosion interlayer of zinc phosphate. [..] Read more

Abstract: The study presents the results of the corrosion resistance and bacteriological research of DC01 steel protected by ZrN, DLC COMP a-C:H and MULTICOMP TiN/TiAlN coatings applied by PVD method (Physical Vapour Deposition). The experiment was divided into two stages. [..] Read more

Abstract: Corrosion failure of metallic electroplated coatings on various products were analysed and the dominant corrosion stimulators were identified. The thickness and porosity of coatings are very important for their corrosion resistance. [..] Read more

Abstract: Water-based coating systems are becoming more popular with consumers due to their simple application and a wide range of colours. The coating systems, in addition to the requirement of nice finishes, are supposed to provide the sufficient protection of background material from corrosion. [..] Read more

Abstract: The corrosion inhibition of steel in the hydrochloric acid solution by N-butylquinolinium bromide and 1-octyl-3-methylimidazolium chloride was investigated using electrochemical and weight loss methods. Both compounds under investigation act as mixed type inhibitors with predominantly anodic action. [..] Read more

Abstract: Besides customers and environmental requirements such as safety increase, the weight and emission reduction, and the life-time improvement, huge role plays corrosion resistance of the car-body components. This is improved by applying Zn-based coatings on the steel sheets. [..] Read more

Abstract: This paper presents the results of testing the corrosion behaviour of K110 tool steel for cold work in industrial emulsion medium (Lenox Band-Ade semi-synthetic oil + water, in a ratio of 1:10), water and 3.5% NaCl medium. Using the method of electrochemical impedance spectroscopy (EIS) and Tafel extrapolation, electrochemical measurements were performed in order to determine the corrosion parameters. [..] Read more

Abstract: Anti-corrosion protective polymer thin films are used to prevent metal contacting with an aggressive environment. It is known that the density of the polymer film coating can be controlled at the stage of formation its. [..] Read more

Abstract: Magnesium alloys used as sacrificial anodes can interact with humic acids (HAs) in soil and water environments. Therefore, these natural organic molecules can have an impact on the corrosion behaviour of magnesium materials. [..] Read more
