Inconel X750 is known for its excellent mechanical and corrosion properties. However, investigations on its tribological performance have not been conducted extensively. In this work, such a study has been performed in dry conditions with varying contact pressures at a constant frequency and stroke length. Additionally, the results were compared with the same alloy under surface hardened conditions. Hardening was achieved by creating surface-level plastic deformation using steel balls. The deformation induced was uniform and more twinning in the grains near the surface was observed with a 20%–40% increase in hardness. Friction and wear behavior were studied using a reciprocating tribometer with a ball on flat configuration at 2 N, 3 N, 4 N, and 5 N with a 1 mm stroke distance. The surface hardened samples showed improvement in wear resistance by 30%–45% at various loads. The competing wear mechanisms found were abrasion and adhesion, depending on the conditions. Transfer layer formation was also observed in regions where adhesion was dominant. However, the onset of adhesion for the surface hardened specimen was late compared to the as-received sample. Furthermore, the geometry of the counter surface material also influenced the wear mechanism prevalent during the tests, such that they hindered the transition from abrasion to micro-adhesion.

Inconel X750 以其优异的机械和腐蚀特性而闻名。然而，对其摩擦学性能的研究尚未广泛进行。在这项工作中，这样的研究是在干燥条件下进行的，接触压力在恒定频率和冲程长度下变化。此外，将结果与表面硬化条件下的相同合金进行了比较。硬化是通过使用钢球产生表面级塑性变形来实现的。引起的变形是均匀的，在靠近表面的晶粒中观察到更多的孪晶，硬度增加了 20%–40%。摩擦和磨损行为是使用往复式摩擦计进行研究的，该摩擦计在平面配置上以 2 N、3 N、4 N 和 5 N 的速度和 1 mm 的行程距离配备了一个球。表面硬化的样品在各种载荷下的耐磨性提高了 30%–45%。发现的竞争磨损机制是磨损和粘附，具体取决于条件。在粘附占优势的区域也观察到转移层的形成。然而，与原样相比，表面硬化试样的粘附开始较晚。此外，反面材料的几何形状也影响了测试过程中普遍存在的磨损机制，从而阻碍了从磨损到微粘附的过渡。与收到的样品相比，表面硬化样品的粘附开始较晚。此外，反面材料的几何形状也影响了测试过程中普遍存在的磨损机制，从而阻碍了从磨损到微粘附的过渡。与收到的样品相比，表面硬化样品的粘附开始较晚。此外，反面材料的几何形状也影响了测试过程中普遍存在的磨损机制，从而阻碍了从磨损到微粘附的过渡。
