We study the influence of rubber transfer films on the sliding friction between rectangular rubber blocks and a concrete surface. We present experimental results for the friction coefficient for a rubber compound sliding on a concrete surface contaminated by another rubber compound, for two different pairs (A, B) and (C, D) of rubber compounds. For the same rubber compounds, we present theory results which illustrate the relative importance of the viscoelastic and adhesive contribution to the sliding friction. We correlate the calculated rubber friction with the nature of the observed transfer films (or wear processes).

橡胶磨损和转移膜在硬质粗糙基材上的橡胶摩擦的作用

我们研究了橡胶转移膜对矩形橡胶块与混凝土表面之间滑动摩擦的影响。我们提供了两种不同的（A，B）和（C，D）对橡胶混合物在混凝土表面上滑动的橡胶混合物的摩擦系数的实验结果。对于相同的橡胶混合物，我们提供理论结果，这些结果说明了粘弹性和粘合剂对滑动摩擦的贡献的相对重要性。我们将计算出的橡胶摩擦与观察到的转移膜（或磨损过程）的性质相关联。
