材料性能在决定磨损性能方面所起的作用仍然不明确。在磨损理论中，硬度仍然是最常用来表示材料性能和磨损率之间关系的术语，尽管它经常被证明不足以达到这个目的，特别是当不同的材料处于磨损状态时。一项工作计划已经开始，目的是建立一个更合适的材料性能术语，用于预测各种钢的磨损寿命。本文首次研究了十四种C-Mn-Si珠光体钢的磨损行为与某些基本材料性能之间的关系。这些钢的严重磨损特性是用销-环磨损试验机测定的，该试验机使用空气喷射冷却，以使销载荷高达200 kgf，而不需要过度的销加热。发现磨损率可与化学组成项（C+Mn/4.75 +Si/10）wt.%相关，微观结构的长期，平均铁素体路径，并从单调和循环应力-应变曲线的强度参数。
The role that material properties play in determining wear behaviour is still ill defined. In wear theory hardness remains the term most commonly used to express the relation between material properties and wear rates although it has often been shown to be inadequate for this purpose, particularly when dissimilar materials are under consideration.A programme of work has been initiated with the aim of establishing a more suitable material property term for use in the wear life prediction of a wide range of steels. In this first investigation the relation between the wear behaviour and some basic material properties of fourteen C-Mn-Si pearlitic steels have been studied. The severe wear characteristics of these steels were determined with a pin-ring wear testing machine using air jet cooling to allow pin loads of up to 200 kgf to be employed without excessive pin heating. It was found that wear rates can be related to a chemical composition term (C+Mn/4.75 +Si/10)wt.%, to a microstructural term, the mean ferrite path, and to the strength parameters derived from both monotonic and cyclic stress-strain curves.
