The application range of magnesium alloys is restricted because of poor tribological performance. The present study focuses on improving the tribological characteristics of magnesium Ze41A alloy by ball burnishing process. The lowest wear rate of 2.997 × (10)⁻³ mm³/m, CoF of 0.116 and interface temperature of 38 °C are obtained by ball burnishing process. The SEM examination at optimum burnishing condition reveals the oxidative wear mechanism, while the milled surface exhibited plastic deformation mechanism under similar wear conditions. The significant enhancement in tribological performance of magnesium Ze41A alloy is apparently due to the improvement in surface roughness and microhardness during ball burnishing process. The wear rate has been decreased by 51.22%, CoF by 72.58 and interfacial temperature by 39.68% at the optimum burnishing condition as compared to initial milling condition under similar wear conditions. Additionally, the tribological performance is evaluated by fuzzy interface system and the model found to estimate the results with an average absolute error of 4.92%.

由于摩擦学性能差，镁合金的应用范围受到限制。本研究的重点是通过球磨工艺改善镁 Ze41A 合金的摩擦学特性。最低磨损率 2.997 × (10) ⁻³ mm ³/m，0.116 的 CoF 和 38 °C 的界面温度是通过球抛光工艺获得的。在最佳抛光条件下的 SEM 检查揭示了氧化磨损机制，而铣削表面在类似磨损条件下表现出塑性变形机制。Ze41A镁合金摩擦学性能的显着提高显然是由于球磨过程中表面粗糙度和显微硬度的改善。与类似磨损条件下的初始铣削条件相比，在最佳抛光条件下，磨损率降低了 51.22%，CoF 降低了 72.58，界面温度降低了 39.68%。此外，摩擦学性能由模糊接口系统评估，该模型估计结果的平均绝对误差为 4.92%。
