Abstract: Modern applications of pneumatic and hydraulic systems in extreme subsea production increased emphasis on long life and minimum maintenance cycles. For this reason, are constantly developed new sealing elements. [..] Read more

Abstract: Manufacturing of the tensile test specimens with minimal surface defects and close tolerances are the key factors to achieve desirable and accurate mechanical properties. In addition, faster and cost-effective manufacturing methods with reliable results are also critical requirements. [..] Read more

Abstract: The paper deals with the evaluation of experimental data on samples of steel wire. The main attention is aimed at the R&R study, which was a part of the experiment for studying effects of three factors on various mechanical properties of drawn wires. [..] Read more

Abstract: This work deals with the proposal for the new evaluation system of calibration data in the VÍTKOVICE STEEL Testing laboratories. The main purpose of this work is the best possible use of the information obtained during regular calibrations of Charpy impact machine performed according to standard ČSN EN ISO 148-2:2010 - Metallic materials – Charpy pendulum impact test – Part 2: Verification of testing machines, and ASTM E23 – 16 Standard test methods for notched bar impact testing of metallic materials.

Abstract: The steel sector is one of the most important sectors of the processing industry in Poland. The article presents the changes in the development of the steel industry in Poland in the years 2010-2014. [..] Read more

Abstract: FMEA method is well known as a tool used especially within the automotive industry. Its purpose is to review risk and increase reliability of product and/or process. [..] Read more

Abstract: Delamination or laminar flaws were sometimes detected during manufacturing and/or plant operations. A laminar flaw is a subsurface flaw parallel to the rolling direction of the plate. [..] Read more

Abstract: In the validation and evaluation of conformity between customer requirements and actually achieved quality of the products is always necessary to take into consideration two contradictory requirements. The first of them is the requirement for the most accurate and highest quality measurements or inspection. [..] Read more

Abstract: Alloys that have lamellar structures, e.g., pearlitic steel, are widely used in practice. Nowadays, perlitic steel wires for tyre cords, springs and ropes are studied extensively at our laboratory of wire drawing. [..] Read more

Abstract: The 1980s was a period of changes in Poland aimed at building a free market economy. This change has greatly influenced the functioning of Polish state-owned enterprises, which had to introduce new management rules. [..] Read more

Abstract: At the beginning of the production of body parts from Al-alloy, there was a requirement to experimentally verify its suitability for their production. This alloy is characterized by a combination of various stress-deformation properties influencing the non-uniform plastic flow of the material, especially during deep drawing of complex shaped drawn parts.

Abstract: The article deals with tribological evaluation of DLC coating. This coating is deposited on a material which, due to its mechanical properties, is suitable for components of weapons and military equipment. [..] Read more

Abstract: In this article, we present the design and preparation of a platform for a gas sensor application based on the ink print of silver nanoparticles on flexible substrates. The Inkjet printing allows localized deposition of ink at low temperatures on a large area and can be used for the deposition of both conductive and dielectric materials. [..] Read more

Abstract: This article deals with the evaluation of the microstructure and tribological and mechanical properties of hardmetal coatings based on WC and CrC, which were applied to the base material S235JR by the HVOF thermal spraying technology. Experiments such as microhardness HV0.3, superficial hardness HR15N, adhesion determination, abrasive wear and reciprocating sliding wear test were performed to compare the properties of the coatings and see how they differ depending on the selected additive material.

Abstract: Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants.

Abstract: We investigate the new alloys of Mg–Ga–Zn–X system, where X = Ca, Y and Nd. These alloys can be used as biodegradable materials due to the low cytotoxicity of Zn and Ga and effectiveness of Ga against bone resorption, osteoporosis and Paget’s disease. [..] Read more

Abstract: Steel reinforcement of concrete structures is normally passivated due to high pH value of concrete interstitial electrolyte (pH 13-14). However, chloride contamination (e.g. [..] Read more

Abstract: The durability of reinforced concrete structures is limited mainly by the reinforcement material, as which a carbon steel is widely used. Carbon steel corrosion rate increases due to carbonation or contamination with chloride anions. [..] Read more

Abstract: The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. [..] Read more

Abstract: The possible differences in the protective performance of Zn and MIO pigmented epoxy coatings for different times of exposure performed during 533 hrs in 0.05 M NaCl were confirmed by new interpretation of ENA data in combination with single frequency (1 kHz) impedance test results. By this approach changes of resistivity and dielectric constant (identified on tested coating system at different times of exposure) can be related to delamination tendency as well as changing possibilities for new defects formation in tested type of coating for different time of exposure..
