| Abstract: |
| The work provides a systematic overview of the research progress and future development trends in the field of wear-resistant coating preparation for steel surfaces by EDM deposition technology in recent ten years, focusing on its technical principles, material applications and process optimization. Firstly, the basic principles of EDM technology, including its process and influencing factors are described. Secondly, from the composition of electrode materials, different wear-resistant coatings, including refractory mono-metal coatings, traditional alloy coatings, high-entropy alloy coatings, amorphous alloy coatings and composite coatings, are analyzed in detail, and systematically discussed from the aspects of deposition conditions, microstructures, hardness, and tribological properties, respectively. Finally, the development trend of EDM deposition technology is described, focusing on the in-depth study of the coating formation mechanism, the development of new coating materials, the optimization of deposition process parameters, the large-area low-cost preparation technology, as well as the automation of the deposition process, so as to provide ideas and directions for the subsequent research in this field. |
