Abstract: The corrosion inhibition of aluminium and steel in the hydrochloric acid solution by 1-octyl-3-methylimidazolium bromide, 1-octyl-3-methylimidazolium hydrogensulphate and 1-dodecyl-3-methylimidazolium bromide was investigated using electrochemical and weight loss methods. The qualitative surface analysis was carried out. [..] Read more

Abstract: The paper presents the results of the study how the sub-zero treatment of Vanadis 6 steel influences the corrosion resistance of the material. The sub-zero treatment was performed at -196 oC in liquid nitrogen for 17 h. [..] Read more

Abstract: The paper offers an analysis of the fluoride conversion coating prepared on ZE10 magnesium alloy with the aim to improve material corrosion properties with respect to the biocompatibility of the alloy. The coating was prepared via unconventional process, by immersion of the alloy in Na[BF4] molten salt at 430 and 450 °C for various treatment times. [..] Read more

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: Phase change materials (PCMs) are now a well-established category of materials for thermal energy storage. Most PCMs need to be hermetically sealed in a container or a storage tank because of the risk of leakage to the surrounding environment when a PCM is in the liquid state. [..] Read more

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: Inhibition of mild steel corrosion in 1 M HCl solution by alkylimidazolium bromides was investigated using electrochemical and weight loss methods. The studied ionic liquids showed appreciable inhibition efficiencies. [..] Read more

Abstract: Plasma nitriding is widely used as a final operation to improve wear, fatigue and corrosion resistance of industrial parts. Nevertheless, corrosion resistance can be further increased by post-oxidizing or by manganese phosphate conversion coating. [..] Read more

Abstract: 1.4301 steel as a basic stainless material used for undemanding applications is studied in this paper. Some of surgical instruments as well as other medical devices are manufactured from this material so its biocompatibility and corrosion resistance must be guaranteed. [..] Read more

Abstract: Plasma nitriding is a great thermochemical treatment, widely used in many technical applications as a final operation to improve the mechanical, tribological and corrosion properties of steel. This article deals with wear and corrosion resistance comparison of plasma nitrided and tenifered 42CrMo4 steel, which is widely used in manufacturing of breech mechanism in the armament production.

Abstract: This report shows first investigation of microstructure development and its effect on mechanical strength and corrosion resistance of non-commercial magnesium alloy WN43 processed extrusion (Ex) and equal-channel angular pressing (ECAP). Bimodal grain size distribution with high volume fraction of ultra-fine grains about 650 nm in diameter was achieved after 4 passes through ECAP. [..] Read more

Abstract: The corrosion resistance of three grades of valve steels (X33CrNiMn23-8, X50CrMnNiNbN21-9, X53CrMnNiN20-8) in combustion gases of propane-butane (LPG) under thermal shock conditions has been studied. It was stated that X33CrNiMn23-8 steel, containing highest concentration of chromium and nickel and also the lowest of manganese concentration, showed the best corrosion resistance in comparison to another tested steels.

Abstract: The subject of the study was to determine the corrosion resistance of the bearing steel 67SiMnCr6-6-4 with a nanocrystalline structure compared to those with the conventional structure of tempered martensite. In order to obtain a nanocrystalline structure one set of steel samples was subjected to heat treatment consisting on quenching and austempering at 240°C. [..] Read more

Abstract: Humic acids are a heterogeneous mixture of organic compounds that are naturally found in water and soil. In recent years, there has been a growing interest in the application of green fertilizers containing humic acids in agricultural activities. [..] Read more

Abstract: One of the recently demanded methods of protecting metal surfaces from aggressive environment is the formation on their surface of continuous films with water-repellent properties and the ability to self-cleaning, which give the material the property of super-hydrophobicity. The possibility of hydrophobization of the surface of the AZ31B magnesium alloy in a solution containing stearic acid, dimethyl sulfoxide and water has been investigated. [..] 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: Household appliances often utilize polymer-metal bonding, typically achieved through adhesive bonding or press-fitting techniques. Corrosion resistance is a major factor in household appliances, as corrosion can compromise the functionality and aesthetics of household appliances. [..] Read more

Abstract: The material in nuclear reactors of the VVER 440 type and their main circulation pipes is exposed to temperatures in the range of 100-300 °C during the operating conditions, but in some nodes can be this range of temperatures exceeded. These temperature conditions are suitable for low-temperature sensitization and the microstructure sensitized in this way may be susceptible to inter-granular corrosion during long-term operation.

Abstract: In this study, the nature of boriding surface treatment mechanism of the steel prestressing strand is evaluated and then the corrosion resistance of the borided steel in hydrochloric acid is assessed (detection of the content of released iron and manganese in the exposure solution). The effect on the bond strength of the treated steel prestressing strand with normal strength concrete is also evaluated (pull-out test). [..] Read more
