Metal Science and Treatment of Metals| Summary: | It was found that titanium and chromium deposition sequence in the process of Electric-spark alloying (ESA) affects the structure, phase composition, microhardness and wear resistance of the near-surface steel zone of steel Art.3. When processed in the Ti-Cr sequence, alloyed layers is 10 –15 microns thickness with a microhardness of 10 GPa, wear resistance of 19 times greater than the unprocessed basis, are formed, while when processed in the Cr-Ti sequence, the thickness of the layer is 15 – 20 microns , microhardness – 6.6 GPa, and wear resistance increases 25 times. |
