BROŽEK MILAN. 2015. Selected Plastics Wear Resistance to Bonded Abrasive Particles Compared to Some Ferrous Materials. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 63(2): 387– 393. Plastics are macromolecular materials without we cannot imagine any branch of human activity with. Plastics have unique properties, o en very diff erent from metals. At the choice of the concrete plastic for the concrete application it is necessary to evaluate its mechanical, physical, chemical and technological properties. In last years producers off er also plastics for production of parts exposed to diff erent types of wear. In the contribution the results of wear resistance studying of 10 types of plastics (PTFE, PVC, POM-C, PC, PETP, PEEK, PA66, PP, PA6E and PE-UHMW) of one producer are published and compared with test results of four diff erent Fe alloys (grey iron, structural steel, cast steel wear resistant and high-speed steel). The laboratory tests were carried out using the pin-on-disk machine with abrasive cloth (according to CSN 01 5084), when the abrasive clothes of three diff erent grits (240, 120 and 60) were used. It corresponds to the average abrasive grain sizes of 44.5 μm, 115.5 μm and 275 μm. During the test the test sample was pressed to the abrasive cloth by the pressure of 0.1 MPa. The wear intensity was assessed by the volume, weight and length losses of tested samples. The technical-economical evaluation was the part of the carried out tests. It was univocally proved that at the intensive abrasive wear using the abrasive cloth the best results shows the High-Speed Steel HSS Poldi Radeco 19 810 according to CSN 41 9810, although its price is relatively high. Other tested Fe alloys, namely grey iron according to CSN 42 2415, structural steel 11 373 according to CSN 41 1373 and wear resistant cast steel VPH 6 showed also very favourable properties at the material low price. In comparison with Fe alloys the wear of all plastics was considerably higher and the plastics were considerably more expensive.
