Abstract: The issue of anti-frost surface treatment is a current research topic, especially in the transport and energy industries. Ice and its formation, adhesion and accumulation can cause serious problems on the surface of wind turbines, solar panels, power lines, roadways, in aircraft industry as in everyday life.

Abstract: The paper presents investigations of the wettability of Al2O3 layers produced by the direct-current method and the reference to its geometrical structure and tribological properties. The layers were made on the aluminum alloy EN AW-5251 using direct-current anodizing at varying production parameters (electrolyte temperature, current density, process time). [..] Read more

Abstract: Material coating is a technology that is used in a variety of materials, and thanks to this adjustment, we improve the surface properties. It increases corrosion resistance, wears resistance, improves a functional quality and changes or improves aesthetic design. [..] Read more

Abstract: The generally applied requirements on lowering of emission production in the field of power industry have led, among others, into the application of low-emission combustion process of coal fired power plants. Besides the emissions reduction, this process has led to an increase of boilers parts corrosion degradation due to the reducing atmosphere in low-emission boilers, responsible for sulphide corrosion and molten salt attack.

Abstract: This paper deals with welding on high-carbon steel that is used for the production of tram and railway tracks. The high-quality and efficient maintenance of the track superstructure, especially the refurbishing of worn rails, is an integral part of the operation of rail transport. [..] Read more

Abstract: This paper shows influence of Laser Shock Peening (LSP) on Residual stress (RS) and Fatigue life of stainless steels. LSP is an innovative surface treatment technique for strengthening metallic materials. [..] Read more

Abstract: This paper presents the influence of laser texturing on the tribological properties of sintered tool materials not coated and coated in the process of chemical deposition from the gas phase. Sintered carbide substrate, sialon ceramics substrate and the Al2O3+TiN coating deposited on sialon ceramic substrate were subjected to laser treatment. [..] Read more

Abstract: This paper presents the possibility of modifying the microstructure of anodic hard coatings on aluminium alloys by applying a pulsed method in the process of their electrochemical deposition. Anodic hard coatings were formed on an aluminium alloy intended for plastic working. [..] Read more

Abstract: Adhesive bonding is a method often used for bonded joints of aluminum alloys preparation. The surface pre-treatment is strongly influencing bonded joints shear strength. [..] Read more

Abstract: In this paper, the preparation and characterization of as-deposited and heat-treated low phosphorus Ni-P coatings on AZ91 magnesium was performed. Heat-treated Ni-P coatings reached the higher microhardness of 1030 ± 20 HV 0.025 when compared to as-deposited Ni-P coatings (560 ± 20 HV 0.025). [..] Read more

Abstract: The article presents an innovative method of metallization of ceramics based on detonation spraying process. New approach consists on exposition of influence mechanical deliver of energy for joining process. [..] Read more

Abstract: One of the methods of protection of metal surfaces from an aggressive environment is the formation of continuous coating on their surfaces with water-repelling properties and a self-cleaning ability, which give the material superhydrophobic properties and also protect them from contamination.A solution for hydrophobization of aluminum alloy 5556 in a solution containing dimethyl sulfoxide and water in a ration of 7:1 and also stearic acid in the amount of 0.01 mol/L was developed.It was determined that the newly-formed coating in this solution is characterized by a contact angle of θс = 151°. The protective ability of coatings determined by the drop method as the time until the appearance of corrosion product under the drop of Akimov solution amounts to 125 s.Corrosion tests of AA 5556 speciments with hydrophobized surface were conducted (ASTM B117) in a salt fog chamber in the developed solution.

Abstract: In this paper presented the main problem of wear of sapphire wire guides on EDM machines significantly affects the quality and accuracy of the machined surfaces. Even small geometrical deviations lead to errors in the technological process. [..] 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 article presents an analysis of the consumption of low-carbon steel and DLC coating working in a sliding combination with rotational motion and in various operating conditions. The influence of selected operational factors, i.e. [..] Read more

Abstract: The martensitic stainless steel AISI 410 was subjected to plasma nitriding at an increased temperature of 550 °C, 24 h in 3H2:1N2 (l/h) nitriding gas ratio and compared to untreated one. The microstructure and microhardness of the untreated and nitrided stainless steel were evaluated. [..] Read more

Abstract: Diamond-like-carbon coatings (DLC) have exceptional chemical, protective and tribological properties. They are increasingly used in industry. [..] Read more

Abstract: Copper and nickel-based solders with embedded particles of various sizes of tungsten carbide are widely used in industry. These particles are characterized by high hardness and abrasion resistance, erosion resistance, etc. [..] Read more

Abstract: The article deals with porosity of compound layers after gas and plasma nitriding. Experiments are focused on using of gas and plasma nitriding processes for surface treatment. [..] Read more

Abstract: In recent years, black nickel-based functional coatings are increasingly being used as a worthy alternative to chromium coatings on steel, since such coatings provide not only an aesthetic appearance, but also effective corrosion protection.The known technologies of applying black nickel coatings do not allow obtaining coatings with the required corrosion and wearing resistance. In addition, these technologies involve the mandatory pre-deposition of copper or nickel underlayer. [..] Read more
