滑动表面的磨合是一个非常复杂的过程，它通常定义了接触的摩擦学特性。为了优化摩擦系统，越来越多的工业研究集中在磨合过程中发生的机理上。这些研究可以受益于在现场摩擦学领域的进展。在这项工作中，我们提出了一种新的方法来测量和分离犁耕和剪切项的摩擦力[1]，在理想情况下的硬球在平面上滑动。实验是用红宝石球和扁钢针在浸在聚α-烯烃（PAO 8）中的扁铜表面上滑动进行的。采用定制的摩擦计来测量磨痕内的犁耕轨迹的加宽。在这些测量中，以线性往复方式进行接触表面的相对运动。比较了犁耕摩擦和滑动摩擦的不同判别方法。我们的研究结果与球形滑块表明，扩大率的磨损轨道是线性成比例的犁项，提供的球体不下沉的铜样品迅速。进一步的实验表明，这种方法扩展到多粗糙系统，以更好地了解在磨合过程中的滑动表面的动态的潜力。
Running-in of sliding surfaces is a highly complex process that often defines the tribological properties of a contact. With a view to optimizing a tribosystem, more and more industrial research focuses on the mechanisms that occur during running-in. Such studies can nowadays benefit from the progress shown in the field of in situ tribometry. In this work, we present a novel approach to measure and separate the plowing and shear terms of the friction force [1], in the ideal case of a hard sphere sliding on a plane surface. The experiments were performed with ruby spheres and flat steel pins sliding against a flat copper surface immersed in poly alpha olefin (PAO8). A custom built tribometer was employed to measure the widening of plowing tracks within the wear scar. In these measurements, the relative motion of the surfaces in contact was performed in a linear reciprocating manner. Different methods to distinguish between plowing friction and sliding friction are compared. Our results with spherical sliders show that the widening rate of the wear track is linearly proportional to the plowing term, provided that the spheres do not sink in the Cu sample rapidly. Further experiments with flat on flat demonstrate the potential of expanding this method to multi-asperity systems in order to better understand the dynamics of sliding surfaces during running-in.
