对于银在干燥的3级砂纸(平均颗粒直径150μm)上的短(类似1 mm)磨损行程，在大约1 kg载荷下估计总沟槽体积。这与质量磨损率进行了比较，因此对于最初在0000砂纸(直径5μm)上堆积的银，估计作为磨损去除的总凹槽体积的比例约为10%；对于最初在干燥的3级砂纸上堆积的银，估计约为30%-40%。这表明，在磨粒周围的塑性流动过程中，大部分磨损功导致金属表面区的变形、滑动和强烈的加工硬化；摩擦系数主要是这种塑性流动的特征，而不是在磨粒犁削过程中金属(磨损)的去除。
The total groove volume is estimated for a short (similar 1 mm) abrasion stroke of silver on dry grade-3 emery paper (mean particle diameter 150 μm) at approximately 1 kg load. This is compared with the mass wear rate, thus giving an estimate of the order of 10% for the proportion of the total groove volume removed as wear, in the case of silver surfaced initially on 0000 emery paper (diameter 5 μm); and approximately 30-40% for the silver surfaced initially on dry grade-3 emery paper. This shows that much of the work of abrasion results in deformation, slip and intense work-hardening of the surface region of the metal during plastic flow round the abrasive particles; and that the friction coefficient is mainly characteristic of such plastic flow, rather than of the removal of metal (wear) during the ploughing action of the abrasive particles.
