Nitrogen ion implantation has shown its role in enhancing steel surface properties. In this work, AISI M50 steel was implanted with nitrogen ions by using the metal vapor vacuum arc technique with a dose of 2 × 10¹⁷ cm⁻², and corresponding implanted energies were at 60 keV, 80 keV, and 100 keV, respectively. The distribution of implanted nitrogen ions was calculated, and the samples were tribologically tested and examined. As shown by the results, the microhardness in implanted samples was 1.17 times greater relative to that of the unimplanted sample. The implantation of the nitrogen ion leads to a change in the friction coefficient of the AISI M50 steel. Adhesive wear mechanism occurs in the unimplanted sample, and adhesion resistance tends to increase when nitrogen-implanted energy increases. The formation of oxides α-Fe₂O₃ and Fe₃O₄ further enhanced the tribological properties for implanted samples.

氮离子注入能量对AISI M50钢机械和化学性能的影响

氮离子注入已显示出其在增强钢表面性能方面的作用。在这项工作中，AISI M50 钢通过使用金属蒸气真空电弧技术以 2 × 10 ¹⁷  cm ^-2的剂量注入氮离子和相应的注入能量分别为 60 keV、80 keV 和 100 keV。计算注入氮离子的分布，并对样品进行摩擦学测试和检查。结果表明，植入样品的显微硬度是未植入样品的 1.17 倍。氮离子的注入导致AISI M50钢的摩擦系数发生变化。未注入样品发生粘附磨损机制，当注入氮能量增加时，粘附阻力趋于增加。氧化物α -Fe ₂ O ₃和Fe ₃ O _{4 的形成}进一步增强了植入样品的摩擦学性能。
