| description | The paper presents the results of metallographic studies and tribotechnical tests of samples of grade 2 wheel steel in the form of bushings, the end surface of which was processed using turning and milling operations. It was found that the greatest influence on the microhardness of the surface layers during milling was exerted by the tool feed rate. When turning samples without coolant, the microhardness of the modified layer is higher than when processing with the use of coolants in various variants. It is shown that three factors influenced the microhardness during turning, the temperature in the cutting zone, the oxidation of the surface and the magnitude of plastic deformations. The regularities of changes in the coefficients of friction from the type of processing were obtained, and after milling they were significantly lower than after the flow. The modified layers after milling had greater depth and wear resistance compared to similar layers after turning. |
