Abstract
Abrasive wear tests are a complex, time-consuming and long-term type of research on the wear-resistant properties of materials. Known methods for the experimental determination of the wear resistance of materials based on abrasive wear require an assessment of the wear resistance corresponding to the characteristics of field tests of parts with reinforcing coatings applied using high- frequency currents. (Research purpose) The research purpose is in analyzing the existing methods of testing for abrasive wear in the development of technological processes to increase the wear resistance of the surfaces of machine parts in comparison with the methodology developed by VIM, as well as comparing the methods of laboratory tests and field tests with the method proposed in this paper. (Materials and methods) Authors chose the IM-01 installation of the VISKHOM design for laboratory research, which uses powder abrasive. The article describes the most similar methods of foreign authors. The drill bits of Amazone seeders were strengthened according to the selected testing technology. The plates with a size of 60x40 and a thickness of 5-7 millimeters were selected as samples for testing the relative wear resistance. According to the VIM method, an abrasive radial petal circle is used as an abrasive material on the M-1 installation. (Results and discussion) The test results are expressed by the relative wear resistance index ε, which is equal to the ratio of the wear resistance of the test sample to the wear resistance of the standard. The use of the relative wear resistance index allows to increase the accuracy of the results obtained due to the exclusion of the influence of natural changes in external parameters that determine the wear rate during the test. (Conclusions) The proposed device makes it possible to provide accelerated comparative tests of samples and improve the stability of obtaining wear characteristics in a relatively short time (with the practical use of the device, the time spent on testing of one sample was about 8 minutes).
