Abstract: The experimental estimation of the fatigue curve is quite expensive and complex. It is very difficult to create an actual reactor's working environment, such as extreme temperatures, etc. [..] Read more

Abstract: Currently, technological development is focused, among other things, on hydrogen and its technologies. Hydrogen storage must be very well secured and material resistance against hydrogen embrittlement is tested using different approaches. [..] Read more

Abstract: This paper investigates the properties of epoxy based coatings modified with antimicrobial metal nano- and microparticles. Surface modifications have been applied to geopolymer materials in order to improve their properties. [..] Read more

Abstract: High Pressure Cold spray (CS) belongs to the family of thermal spraying technologies. The technology consists in accelerating microscopic particles to supersonic speed and depositing them on a substrate, where kinetic energy is converted into deformation and thermal energy at the moment of impact. [..] Read more

Abstract: The weight reduction of vehicle body and parts become much more crucial to decrease CO2 emissions. The use of high-strength steels has increased within the scope of vehicle weight reduction studies. [..] Read more

Abstract: In this study, the effect of citric acid as a chelating agent on the microstructure, chemical, and phase composition of hydrothermally prepared CaP coatings on AZ31 magnesium alloy was observed. The coatings were deposited in a reaction mixture at pH 5, 7, and 9, where the concentration of the chelating agent was set at 5, 50, and 500 mM, respectively. [..] Read more

Abstract: Magnesium alloys are characterized by high corrosion rates. This undesirable phenomenon can be slowed down by corrosion inhibitors. [..] Read more

Abstract: The aim of the present study was to investigate the effect of the concentration of precursors in the reaction mixture on the microstructure and electrochemical corrosion properties of MgAl-LDH coatings deposited on magnesium alloy AZ31. The concentrations of precursors Mg(NO3)2 and Al(NO3)3 were set to 0.10, 0.05, and 0.02 M and 0.10, 0.05, and 0.02 M, respectively. [..] Read more

Abstract: Magnesium and its alloys are very promising candidates for the development of degradable implants, but their application is limited by high corrosion rates. The corrosion resistance of magnesium materials can be increased by suitable surface treatment. [..] Read more

Abstract: In this paper, the main advantages of GDOES profiling analysis in evaluating the thickness of zinc coating applied using hot-dip and electroplating technology on steel sheets are assessed, including the evaluation of electroplating zinc coating with a chromate and chromite passivation layer.Zinc coating is one of the surface treatments of steel products and structures in order to protect them against corrosion attack by the surrounding aggressive environment and contributes to increasing their service life. The thickness, phase structure, and chemical composition of the Zn coating influence its protective properties. [..] Read more

Abstract: The use of anti-corrosion paint coatings on steel pipes is a common practice for their protection against corrosion. However, such coatings may have an impact on the results of the thermographic inspection, which can be used, for example, for their corrosion damage identification. [..] Read more

Abstract: Manufacturers like Airbus have strict specifications concerning the process sequence of fuselage shell forming. Coating may only take place after forming, because conventional processes induce large deformation which could cause coating failure. [..] Read more

Abstract: Because of a limited source of germanium and its high demand caused by growing technology industry, secondary sources become attractive and suited alternatives. In the present paper copper slag containing germanium was used as source and aluminothermic reduction was adopted as mode of reduction. [..] Read more

Abstract: The metallurgical industry is characterized by significant consumption of material and energy resources. The natural resources used are primarily non-renewable. [..] Read more

Abstract: This work deals with the development of the preparation route for the composites with nickel aluminide reinforced by FeSi particles. The optimization of mechanical alloying of individual phases, mixing and consolidation by spark plasma sintering is presented. [..] Read more

Abstract: The historical organ pipes used to be manufactured from tin and tin-lead alloys. The tin-rich organ pipes usually contained copper as alloying elements, which make them similar to modern lead free soldering materials. [..] Read more

Abstract: The high carbon ferromanganese process produces an alloy saturated with carbon. The alloy contains Mn metal, Fe and C. [..] Read more

Abstract: Thermoelectric generators represent a unique way for recovering waste heat. Modules are made from specialized materials with thermoelectric properties. [..] Read more

Abstract: Currently, an avalanche of technology development can be observed, which results in an increase in the production and sale of electrical and electronic devices. The lifetime of electronic components, which at the end of the 20th century was 4 to 6 years, was shortened to 2 years in the first decade of the 21st century, and even to 9 months in the case of mobile phones.

Abstract: Complex concentrated alloy (CCA) with a nominal composition Al0.4CoCr1.3FeNi1.3(Si, Ti, C, B)0.4 was prepared at two different solidification conditions. Centrifugal casting (CC) of the CCA was applied due to the turbulent filling of a graphite mould at non-steady solidification conditions and directional solidification (DS) was performed at steady-state solidification conditions.
