本研究利用纳秒脉冲激光在5A06铝合金表面制备了不同设计参数的微槽。在球盘摩擦磨损试验机上进行了低至-100℃的干滑动磨损试验，考察了设计参数对激光表面织构5A06铝合金摩擦磨损特性的影响。从摩擦行为和磨损形态两个方面分析了表面织构的形成机理。实验结果表明，激光表面织构的设计参数对5A06铝合金的摩擦学性能有重要影响。合理的激光表面纹理可以成功地提高摩擦学性能，这要归功于其捕获碎屑的能力，以防止二次磨损。
In this study, micro-grooves with varying design parameters were fabricated on 5A06 aluminium alloy by a nanosecond pulsed laser. Dry sliding wear tests were performed on a ball-on-disc tribometer at the temperature as low as -100°C to evaluate the influence of design parameters on the friction and wear characteristics of laser surface textured 5A06 aluminium alloy. The mechanism of surface texture is analysed from two aspects of friction behaviour and wear morphology. The experimental results show that the design parameters of the laser surface texture have an important influence on the tribological performance of 5A06 aluminium alloy. Reasonable laser surface texture can successfully enhance the tribological performance, thanks to its ability to capture debris to prevent secondary wear.
