Abstract: The alloys based on intermetallic phases involving aluminum belong to group of heat resistant materials. Their physic-chemical and mechanical properties allow to apply them in the operating conditions in corrosive environment and elevated temperature. [..] Read more

Abstract: The results of corrosion resistance of aluminum alloy 5754 used as a construction material in the automotive industry has been presented in the paper. The samples of aluminum alloy were exposed to acetic salt spray, containing copper chloride as a corrosion initiator, according to ISO 9227: 2012 and the following methods: linear polarization, potentiodynamic cyclic voltametry according to PN-EN ISO 10271: 2012 and impedance spectroscopy according to PN-EN ISO 16773: 2009.

Abstract: Zn and Zn-based alloys attract interest due to an ability to protect steel surface against corrosion. Thin surface layer of a protective zinc alloy is usually prepared by hot dip galvanizing and acts as a barrier against corrosive environment or as a sacrificial anode in case the bare steel surface is exposed.

Abstract: This paper presents the results of testing the corrosion behaviour of K110 tool steel for cold work in industrial emulsion medium (Lenox Band-Ade semi-synthetic oil + water, in a ratio of 1:10), water and 3.5% NaCl medium. Using the method of electrochemical impedance spectroscopy (EIS) and Tafel extrapolation, electrochemical measurements were performed in order to determine the corrosion parameters. [..] Read more

Abstract: The paper presents the results of laser processing of diffusion boronized layer on 145Cr6 tool steel. The aim of the study was to investigate the microstructure, phase composition analysis, microhardness as well as corrosion resistance of the newly-formed layer. [..] Read more

Abstract: Titanium stabilized stainless steel 08Ch18N10T is widely used in VVER nuclear power plants. The alloy 800H is a very promising structural material for application in future nuclear power plants working under more severe working conditions. [..] Read more

Abstract: Plasma electrolytic oxidation (PEO) coatings with and without calcium phosphate (CaP) were prepared on AZ31 magnesium alloy including the CaP coating on AZ31 alloy. The microstructure of all coatings was characterized using an electron scanning microscope with energy dispersive spectroscopy (SEM/EDS). [..] Read more

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: High alloyed materials are required by certain industrial sectors as is power, chemical and nuclear industry, etc. These materials have superior mechanical properties and are resistant to chemically aggressive environment in which it must accommodate the long term mechanical stresses at high temperatures. [..] 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
