金属切削的摩擦学系统的特点是条件苛刻。高应力和咬合以及高温和新生成的表面定义了独特的摩擦系统。因此，许多在低相对速度和温度下的摩擦学试验不能代表金属切削条件，并且几乎不可能推导出摩擦和磨损的定量关系。采用粉末冶金方法制备了一种含有不同含量Al_2O_3磨粒的铁素体-珠光体钢，并对其进行了机械加工，研究了涂层和未涂层刀具在金属切削条件下的磨粒磨损。使用不含任何磨料颗粒的样品作为参考来量化在工件材料中添加0.5wt%、1wt%和2wt%的Al 2 O3的效果。而在刀具后刀面上，磨损率随磨粒含量的增加而逐渐增大，而前刀面磨损率与Al_2O_3的添加量无关。结果表明，金属切削条件下的磨料磨损率在初始阶段较高，但随着切削时间的延长而显著降低。这一现象的加工理论的背景下进行了讨论。
The tribological system of metal cutting is characterized by severe conditions. High stresses and seizure as well as high temperatures and freshly generated surfaces define a unique tribosystem. Therefore, many tribological tests at low relative speeds and temperatures do not represent metal cutting conditions and the derivation of quantitative relationships for friction and wear is hardly possible. By means of powder metallurgy a ferritic-pearlitic steel with varying content of abrasive Al2O3particles has been manufactured and machined in order to investigate abrasive wear under metal cutting conditions for coated as well as uncoated cutting tools. A sample without any abrasive particles is used as a reference to quantify the effect of the addition of 0.5 wt%, 1 wt% and 2 wt% of Al2O3in the workmaterial. Whereas on the flank face of the cutting tools, the wear rate progressively increases with the content of abrasive particles, the rake face wear does not depend on the added content of Al2O3. The results show that the abrasive wear rate under metal cutting conditions is high in initial stages but decreases considerably over cutting time. This phenomenon is discussed against the background of machining theory.
