    Opis:
    Purpose: The aim of the article is to present the thermal, electrical and mechanical properties of the produced polymer composites with a filler in the form of charcoal powder. Design/methodology/approach: The tests were carried out on samples of pure polypropylene (PP) and polymer composites, the matrix of which is polypropylene (PP), and the filler was charcoal powder with a volume fraction of 10%, 20%, 30%, 40% and 50%. The tested polymer composites in the form of granules were produced by extrusion, and then standardised test profiles were made by injection moulding. Findings: The hardness of the tested composites was determined by the Shore D method, the grain size distribution of the filler used was determined using the laser method and its thermal stability was tested using the TGA thermogravimetric analysis. The volume and surface resistivity were also determined and the density was determined. It was found that the charcoal powder used as a filler is characterised by high thermal stability - up to 600°C - and with an increase in its volume share in the polymer matrix, the hardness and density of the produced composites increases. Practical implications: The tested composites can be used as structural composites for complex elements requiring high hardness and strength. Originality/value: The research results indicate the possibility of using charcoal as a filler in polymer matrix, which, due to its low production cost, may be an alternative to expensive carbon fillers.

    Opis:
    W ostatnich kilkunastu lat można zauważyć wzrost zainteresowania materiałami kompozytowymi WPC. W artykule przedstawiono charakterystykę tych materiałów wzmacnianych naturalnymi surowcami. Istotną ich zaletą jest między innymi możliwość otrzymywania kompozytów tradycyjnymi metodami przetwórstwa plastycznego (wytłaczania i wtryskiwania). Ze względu do dobre własności wytrzymałościowe i użytkowe, a także atrybuty wizualne, znalazły zastosowanie na deski tarasowe, place zabaw, balustrady, pokrycia dachowe itp.
    During last years a growing interest could be noticed in WPC composite materials. It is characteristics of these materials reinforced with natural raw materials presented in this article. Definitelly crucial advantage is, among others, the possibility of obtaining composites by traditional methods of plastic processing (extrusion and injection). Due to the good mechanical and functional properties, as well as visual attributes, they were applied to patio boards, playgrounds, balustrades, roof coverings, etc.

    Opis:
    This elaboration shows the effect of combined heat treatment and cold working on the structure and utility properties of alloyed copper. As the test material, alloyed copper CuTi4 was employed. The samples were subjected to treatment according to the following schema: 1st variant - supersaturation and ageing, 2nd variant - supersaturation, cold rolling and ageing. The paper presents the results of inicrostructure, hardness, and abrasion resistance. The analysis of the wipe profile geometry was realized using a Zeiss LSM 5 Exciter confocal microscope. Cold working of the supersaturated solid solution affects significantly its hardness but the cold plastic deformation causes deterioration of the wear resistance of the finally aged CuTi4 alloy.

    Opis:
    This paper presents the influence of casting method and anodic treatment parameters on thickness and structure of an anodic layer formed on aluminium alloys. As test materials was used the aluminium alloy AlSi9Cu3, which was adopted to the casting process and anodic treatment. In this paper are presented the wear test results and metallographic examination, aswell as hardness of non-anodised and anodised alloys subjected to anodising process.The investigations were performed using light and electron microscopy (AFM) for the microstructure determination. The morphology and size of the layer was also possible to determine. The anodising conditions for surface hardening and itsinfluence on properties was analysed. The structure of the surface laser tray changes in a way, that there is a different thicknessof the produced layer. The aluminium samples were examined in terms of metallography using the optical microscope withdifferent image techniques as well as light microscope. Improving the anodization technology with appliance of differentanodising conditions. Some other investigation should be performed in the future, but the knowledge found in this researchconcerning the proper process parameters for each type of alloy shows an interesting investigation direction. The combinationof metallographic investigation for cast aluminium alloys - including electron microscope investigation - and anodisingparameters makes the investigation very attractive for automobile industry, aviation industry, and others, where aluminium alloys plays an important role.

    Opis:
    Purpose This study focuses on determining the best possible structure of the orthosis made with FDM 3D printing technology. To produce the samples, a thermoplastic PLA material was selected that met the conditions of biodegradability, biocompatibility and non-toxicity. The samples produced were subjected to a tensile strength test and corrosion resistance. Design/methodology/approach Studies based on FEM analysis were carried out using the advanced engineering software CAE - Inventor. The samples were designed in the CAD system, while the G-Code path was generated using the PrusaSlicer 2.5.0 program dedicated to the Prusa i3 MK3S+ printer, which was used to create the models. Surface morphology observations of PLA were carried out with a Zeiss SUPRA 35 scanning electron microscope (SEM). The static tensile test was performed on the Zwick/Roell z100 device based on the PN-EN ISO 527:1 standard. Electrochemical corrosion tests were carried out using the Autolab PGSTAT302N Multi BA potentiostat in Ringer solution at a temperature of 37ºC. Findings The research allowed the appropriate structure of the orthosis made of PLA polymer material using 3D FDM printing technology. The static tensile test, SEM and corrosion tests confirmed the correct application of this material for the selected purpose. It was possible to determine that samples with holes of 10 mm had the highest strength properties. Due to the tensile tests, the average tensile strength of those samples was around 61 MPa. The corrosion parameters of PLA were determined using Tafel analysis. Research limitations/implications The research methodology proposed in work can be used to study other biomedical materials. The results presented can be the basis for further tests in order to search for the best orthopaedic stabiliser. Originality/value The innovative part of the article are three different versions of structures intended for making orthoses used in medicine.
