在不同的外加载荷和不同的磨粒尺寸下，测量了铜样品与碳化硅砂纸接触短距离滑动形成的凹槽数量和尺寸，发现磨粒与金属表面之间的相互作用本质几乎与磨粒尺寸无关。在所有情况下都发现了大范围的凹槽宽度。约50%的磨粒以细屑的形式与表面接触，随载荷的增加，形成的沟槽数增多，而平均沟槽宽度变化不大。根据这些结果，对滑动磨损中磨粒尺寸对磨损率的影响提出了初步的解释。这种解释是基于这样的部分，即仅与金属弹性接触的颗粒在支撑所施加的载荷时起作用，而不有助于材料去除。
The number and size of grooves formed on copper samples by sliding for a short distance in contact with silicon carbide abrasive papers was measured for various values of the applied load and for a wide range of abrasive grit sizes.It is found that the nature of the interaction between the abrasive grain and the metal surface is virtually independent of the grit size. A large range of groove widths is found in all cases. Approximately fifty percent of the grains contacting the surface remove material in the form of a fine chip.An increase of the applied load leads mainly to an increase of the number of grooves formed while the average groove width varies only slightly.On the basis of the results a tentative explanation for the influence of abrasive grain size on the wear rate in sliding abrasion is advanced. The explanation is based on the part that particles in only elastic contact with the metal play in supporting the applied load without contributing to material removal.
