Abstract. On the basis of computational and experimental studies, topical problems of choosing the most effective tools for determining the wear of materials by the method of artificial bases are considered and solved. The main attention is paid to the problems of ensuring the accuracy, reliability and availability of tools, taking into account the required range of linear and volumetric wear when using friction pairs with constant and variable specific pressure.
Keywords: pressure, disk, wear, wear resistance, material, tribometer, sample, evaluation, friction, chord
