Abstract: This scientific activity aims to investigate the effect of varying parameters of nitrogen ion implantation on the tribological properties of the nickel alloy Inconel 718. Given the widespread application of Inconel 718 in machinery construction, nuclear engineering, and aerospace, the planned research holds crucial significance in mechanical engineering. Ion implantation is an advanced surface modification method for metals and their alloys, which can lead to a reduction in friction coefficient and wear. However, the impact of this technique on Inconel 718 alloy has not been sufficiently studied to date. As part of this scientific activity, pilot experimental studies will assess the influence of different implantation parameters, such as energy and dose of nitrogen ions, on the material's tribological properties. Samples of Inconel 718 alloy will be subjected to implantation using varied process parameters. The research methods will include tribological tests using the "ball-on-disc" method, nano-hardness measurements, and structural analyses employing X-ray diffraction (GXRD) and scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS). This approach will allow for a comprehensive evaluation of the impact of implantation on the microstructure, mechanical properties, and tribological performance of the material, which is essential from the standpoint of implementing the results in mechanical engineering. This preliminary scientific activity serves as a foundation for preparing a larger research project to develop an advanced model to optimize the ion implantation process. The research findings are planned to be published in a renowned scientific journal listed in the Journal Citation Reports (JCR), contributing to the advancement of knowledge in the field of mechanical engineering and surface modification of metal alloys.
