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: This paper deals with an assessment of the corrosion resistance of copper-basalt composite cladded by laser. The filler powder for laser overlaying was a mixture of high-purity copper powder Oerlikon METCO 55 consisting of 45–90 µm particles and a basalt powder comprising particles 50–250 µm in size.

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: Steels in the cooling water circuits are most vulnerable to localized corrosion, crevice corrosion or deposit corrosion, intergranular corrosion. Austenitic steels excel in their resistance to corrosive environments. [..] 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: In this paper, protective properties of polymer films on the metal surface are analyzed. The simulation is performed by means of the Monte-Carlo method on the basis of three-dimensional lattice model of polymer system with orientational interactions [1]. [..] Read more

Abstract: In the work fasteners - screws M8*80 made of carbon steel 23MnB4 were being examined that are conventionally protected against the corrosion by zinc galvanizing. The research aim was to compare the lifetime/effectiveness of different zinc coatings (galvanic, hot-dip and lamellar), as the anticorrosion protection of steel fasteners. [..] 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: Zn and Mg- based alloys are promising materials for medical implants because the mechanical characteristics of their alloys are close to human bone and zinc and magnesium are relatively non-toxic. In addition, magnesium is well-known for providing optimum corrosion rates under specific conditions. [..] 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: High temperature corrosion is a serious problem related to the combustion of heavy oils with high vanadium contents. Protective overlay coatings are used to allow functioning of engineering components under extreme conditions and provide corrosion resistance to extend the component life. [..] Read more

Abstract: The microstructure, hardness, and corrosion behavior of Cu-modified austenitic stainless steels (SS) were investigated in the present work. The materials were prepared by controlled melting of SS (chemical composition Cr 22 wt. [..] 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: Although high-strength structural steels deliver excellent strength-to-weight ratios, their fatigue reliability drops sharply once corrosion pits develop. In this study, S460 specimens were corroded in controlled salt spray cycles. [..] Read more

Abstract: This study investigated how boronizing affects the electrochemical corrosion behaviour of boronized carbon steel 1020 (0.049 wt.% C and 12.700 wt.% B) and stainless steel 304 (0.003 wt.% C and 8.940 wt.% B). Both materials were boronized using Borax powder at 900°C for eight hours, forming boride layers on their surfaces. [..] Read more

Abstract: Fluoride conversion coatings are perspective surface treatments for reducing corrosion rate of magnesium and its alloys. This work focuses on the preparation of fluoride conversion coating on magnesium material prepared by powder metallurgy. [..] Read more
