Abstract The performance of metal cutting tools is drastically affected by the presence of hard coatings, which promote higher productivity and superior quality to the machined components. Nevertheless, the conventional properties are not capable to fully predict the behavior of the tool during the operation. The surface energy of solids is a characteristic which affects the contact interactions in sliding, i.e., adsorption, wetting and adhesion. However, one of the reasons why surface energy is often neglected in tribological studies is the lack of understanding concerned with the correlation between them, mainly for friction without lubricant. This work investigates the applicability of the surface energy as a property which can be associated with the performance of AlCrN and TiAlN coated materials.

分析 ALCrN 和 TIAlN 涂层摩擦学行为中的表面能相互作用

摘要 硬质涂层的存在极大地影响了金属切削刀具的性能，这有助于提高加工部件的生产率和质量。然而，常规属性不能完全预测工具在操作过程中的行为。固体的表面能是影响滑动接触相互作用的一个特性，即吸附、润湿和粘附。然而，表面能在摩擦学研究中经常被忽视的原因之一是缺乏对它们之间相关性的理解，主要是没有润滑剂的摩擦。这项工作研究了表面能作为与 AlCrN 和 TiAlN 涂层材料性能相关的特性的适用性。
