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: 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: 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: 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: 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: 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: 3D printing is a modern and widely used technology that has reached virtually all sectors of human activity, from the automotive industry to medical fields. Silver nanoparticles (AgNPs) have considerable industrial potential and are intensively studied regarding their antibacterial capability. [..] Read more

Abstract: This work summarizes results and progress in new method development for identification of material properties of steel. This work deals with application of the small punch test for evaluation of material degradation of power station in the Czech Republic within the project TE01020068 “Centre of research and experimental development of reliable energy production, work package 8: Research and development of new testing methods for evaluation of material properties”. [..] Read more

Abstract: Residual stresses exist in material independently of the presence of any external loads. Their presence may not be readily apparent and so they may be overlooked or ignored during a process of engineering design. [..] Read more

Abstract: This paper deals with using the design of experiments (DOE) during the evaluation of mechanical properties of the wire for steel ropes. It was provided with a full factorial experiment with three factors at two levels. [..] Read more

Abstract: This study presents the evaluation, based on the principles of Toyota management (BOST method) of functioning of the manufacturing process in production of components for combine harvesters such as: straw chopper knives and knife sections. These parts perform specific motion during work and require maintaining the dimensions and weight within specific tolerances. [..] Read more

Abstract: Many power plant operators are currently struggling with the problem of expiring the design life of components. The question often arises whether to continue the operation of the equipment or if it is already necessary to shut down/overhaul it. [..] Read more

Abstract: One of the many interesting properties of silver nanoparticles is their antimicrobial activity. Since these properties are related to the morphology of the particles, it is interesting to pay attention to the antimicrobial effects of various metal nanostructures, which differ in the method of synthesis, size, or shape. [..] Read more

Abstract: To ensure proper maintenance and remaining lifespan of railway axles it is important to correctly estimate its mechanical properties. In past many methods were introduced and standardized. [..] Read more

Abstract: Mining industry is still the only supplier of mineral resources. Loading and transportation represents an integral part of the logistics system in each mining company. [..] Read more

Abstract: The durability of materials working in aggressive environments is mostly important in the design of structures and devices. Corrosion destruction is one of the main causes of material losses, reduced efficiency and safety of their use. [..] Read more

Abstract: The paper presents the results of studies aimed at determination of corrosion resistance intermetallic phase matrix of FeAl alloy in a steam environment at 850 °C. The comparison of heat resistance of Fe40Al5Cr0,2TiB intermetallic alloy with heat-resistant steel with austenitic structure X25CrMnNiN25-9-7 was also presented at the article. [..] Read more

Abstract: Report deals with the occurrence of copper and copper oxides in the Heating Plant heat-transfer circuit, particularly in the steam-water system of high pressure steam boilers. Boilers produce high-pressure superheated steam, which is used for cogeneration of heat and electricity. [..] Read more

Abstract: Carbon steels as a construction materials are still very popular, but exposed to corrosion. Low-carbon steel is often used as a construction material for agricultural equipment. [..] Read more
