Abstract: To control the spread of pathogens in hospital environments, good hygienic routines based on cleaning and disinfection of surfaces contaminated with biological materials, are obligatory requirements. Ambulance transporting patients with infectious diseases may often be contaminated because of the special construction and the narrow space inside, ventilation system, and all the devices present.

Abstract: Laser marking is the modern industrial application for non-contact surface modification. An incidence of a laser beam on the marked surface causes material and structural changes, which lead to optical changes of the surface. [..] Read more

Abstract: In this work, the microstructural changes of nickel coated aluminium and hydronalium substrates were investigated after the heat treatment above the melting point of pure aluminium. The 99.0Ni powder was used to produce the coating using high velocity oxyfuel spraying on 5 mm thick 99.5Al and AlMg3 sheets surface. As-sprayed samples were annealed in the temperature range of 660 - 800°C in ambient atmosphere. [..] Read more

Abstract: From the large number of available metals with the memory of shape only a few of them found clinical application. Biocompatible orthodontic wires, applied in case of false occlusion reconstruction, are made of intelligent materials and components. [..] Read more

Abstract: The paper is focused on the fatigue strength in material research. The aim was evaluation of influence of plasma nitriding technology to fatigue strength. [..] Read more

Abstract: This paper tries to determine the possibilities of application of the high temperature oxidation of cast iron as a way of surface preparation before hot-dip zinc galvanizing and presents also results of corrosion resistance tests of zinc coatings created after high temperature oxidation of grey cast iron (with flake graphite). Research was focused on elements of overhead power lines - the jaw-chuck (screw-bow). [..] Read more

Abstract: Eutectic ceramic Al2O3-ZrO2-SiO2 also termed Eucor (as a top coat) and CoNiCrAlY (as a bond coat) coatings were sprayed onto the surface of recently developed fine-grained cast polycrystalline nickel-based superalloy Inconel 713 LC by means of water stabilized plasma (WSP) and atmospheric plasma spraying (APS) techniques, respectively. Specimens were subjected to isothermal oxidation at 1050 °C for 10, 50, 100, 200 and 500 hours in ambient atmosphere, prior to which a half of the as-sprayed specimens was annealed at the temperature of 950 °C for 10 hours.

Abstract: The paper summarizes the results of first series of laser cladding experiments. New system combining the solid state disc laser with power up to 5.3 kW and cladding head with coaxial powder feeding was used. [..] Read more

Abstract: The paper contains the second part of the research which compares corrosion and mechanical properties of different zinc coatings. The following methods of zinc coating were applied: galvanic (PN-EN ISO 4042), hot-dip (PN-EN ISO 10684) and lamellar (PN-EN ISO 10683). [..] Read more

Abstract: Active thermography is an advanced experimental procedure, which uses a thermography measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact infra-red non-destructive testing (IR-NDT) of materials. [..] Read more

Abstract: The laser scanning method uses a small laser spot in combination with a laser scanning head. The method is based on a very fast laser beam sweeping executed by the scanning head perpendicularly to the main laser treatment trajectory. [..] Read more

Abstract: This paper deals with the evaluation of sheets utility properties with zinc coatings and their utilization at car-body stampings production. Analysis of utility properties is carry out both for commonly used zinc coatings for car-body stampings production (Z100) and for newly developed zinc coatings – new type (ZM). [..] Read more

Abstract: The 37MnSi5 steel samples were coated by TiB2 ceramic using electro spark deposition. Then the thermal shock behavior of coated and uncoated steel samples was observed using 5kW vertical solar furnace at Plataforma Solar de Almeria, Spain. [..] Read more

Abstract: The actual theme is study of immunity corrosion - proof steels used in food industry against corrosive environment of washing agents. The experimental work samples were used with two types of surface of the blade. [..] Read more

Abstract: Technical standards are developed by a panel of experts, within a technical committee in frame of various standardisation organisations. The most important are ISO and ESS - the European standardization system (ESS) comprises the three recognised European Standards Organisations (ESOs) - CEN, CENELEC and ETSI. [..] Read more

Abstract: The paper deals with evaluation of PVD functionally graded coatings based on Cr-Al-N, TiN and Ti-Al-N. Coatings were deposited in the following combinations: CrAl/CrAlN, Cr/CrN/CrAlN, nitriding/Cr/CrN/CrAlN, nitriding/TiN/AlTiN and nitriding/AlTi/AlTiN. As main criteria for coatings properties and quality comparison methods of scratch test and nanohardness measurement were selected. [..] Read more

Abstract: Coating of the thin layers is a direct way to increase productivity and tool life. To enhance these benefits, there are a number of finishing operations. [..] Read more

Abstract: The content of this article is comparing the results of measurement of residual stresses using the X-ray diffraction and Barkhausen noise. These two processes are often used in academic research. Currently, they are no longer in use except for when the output control of real heavy-duty machine parts is required to be measured.

Abstract: DHP Copper tubes are frequently used in industrial applications with their unique characteristics such as high corrosion or excellent erosion resistance. Due to the requirement of good quality production, an excellent global factor is needed for the purpose of obtaining high mechanical properties. [..] Read more

Abstract: Biodegradable materials are developed for designing temporary medical implants, like fixation devices for fractured bones or stents. At present, polymeric biomaterials such as poly-lactic acid (PLA) are currently used in these applications. [..] Read more
