| Popis: | The authors propose a novel model accounting for the hardness of materials in a simplified algorithm in order to evaluate their wear resistance by the “block-on-ring” method during tests on a friction machine. This work is relevant for the study of the factors influencing wear and continues to improve this method based on the Taylor series and the testing results for a number of materials in a wide range of hardness. The problem is solved by correlation analysis of the dependence of the hardness of materials on the Mohs scale on the experimental wear parameters, including the volumetric wear resistance of these materials. A complete software that has been developed implements a simplified version of the “blockon- ring” method for wear testing of materials, taking into account their hardness. The high correctness and efficiency of the proposed model is confirmed by the increasing hardness of a polytetrafluoroethylene composite filled with ultrafine diamond. Practical significance. The model of the relationship between the wear resistance and the hardness of materials proposed and justified in the paper is ready for use in their tests by the “block-on-ring” method in production conditions. |
