Abstract Self-regulating tribological behavior of the Ti-component is investigated by preparing MgAl (MA) microchannels to extend their application scope while retaining their longevity and high accuracy. Considering a ball-on-flat tribo-pair system, MA self-regulation improved the tribological behaviors of Ti–MA compared to that of Ti alloys. Notably, MA deformation fluidity, which was enhanced with spherical Al2O3 and multilayer graphene, enabled the excellent MA self-regulation, and improved Ti–MA–graphene and Ti–MA–Al2O3 tribological properties compared to Ti–MA. Al2O3 and graphene contributions significantly accelerated the MA deformation, and enhanced self-recovery of the interface and led to acquisition of favorable self-healing morphology for the excellent tribological self-regulation, among the laser additive manufacturing samples. The obtained results are helpful in evaluating tribological characteristics for commercial application and conceptualizing possible solutions.

Ti合金中制备的MgAl微通道的自调节摩擦学功能分析

摘要 通过制备 MgAl (MA) 微通道来研究 Ti 组件的自调节摩擦学行为，以扩展其应用范围，同时保持其寿命和高精度。考虑到球对平面摩擦对系统，与钛合金相比，MA 自调节改善了 Ti-MA 的摩擦学行为。值得注意的是，与 Ti-MA 相比，球形 Al2O3 和多层石墨烯增强了 MA 变形流动性，实现了优异的 MA 自调节，并改善了 Ti-MA-石墨烯和 Ti-MA-Al2O3 摩擦学性能。在激光增材制造样品中，Al2O3 和石墨烯的贡献显着加速了 MA 变形，并增强了界面的自恢复，并导致获得了良好的自愈形貌，以实现优异的摩擦学自调节。
