Abstract: Magnesium alloy Mg-4Y-3Nd was prepared by spark plasma sintering technique. The gas-atomized powder was sintered at temperatures in the range of 400-500 °C and holding time up to 10 minutes. [..] 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: The zinc coating and/or zinc alloyed coating is one the most frequently used type of corrosion protection. This study was carried out to investigate and evaluate the corrosion behaviour of aluminium zinc alloy coated steel sheet at atmospheric condition. [..] Read more

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: 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: 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: In this work, the processes of applying protective conversion coatings based on rare-earth metal compounds for passivation of the surface of a Zn-Ni alloy were investigated. The mechanism of formation, composition and corrosion characteristics of passivating films were investigated. [..] 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: 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
