The wear behavior of tire tread rubber composites has attracted widespread attention of researcher duo to its serious environmental pollution and high frequency of occurrence for a long time. Herein, a new test method is developed, an improved Akron friction testing machine on a laboratory scale was utilized to estimate the wear loss and mechanism of the rubber composites under rolling and sliding coupling condition. The results indicated that the wear loss quickly increases with the increase of the relative sliding velocity. The main wear mechanism, including adhesive, thermofatigue, tear and curl wear, was governed by the thermal deposition of the worn surface. Scanning electron microscope analysis showed thermal decomposition tear region gradually expanded on the worn surface by increasing relative sliding velocity. The heat distribution numerical analysis supported the experimental results, which confirmed that the heat distribution of the worn surface is entirely consistent with the distribution of the thermal decomposition tear region.

一种评估滑动和滚动条件下橡胶复合材料磨损性能的新方法

轮胎胎面橡胶复合材料的磨损行为由于其严重的环境污染和长期高发生频率而引起了研究人员的广泛关注。在此，开发了一种新的测试方法，在实验室规模上使用了改进的Akron摩擦测试机来估计橡胶复合材料在滚动和滑动耦合条件下的磨损损失和机理。结果表明，磨损损失随着相对滑动速度的增加而迅速增加。主要的磨损机理，包括粘合剂，热疲劳，撕裂和卷曲磨损，是由磨损表面的热沉积决定的。扫描电子显微镜分析显示，通过增加相对滑动速度，热分解撕裂区域逐渐在磨损表面上扩展。
