现代机械表面优化工艺已经超越了简单的经验技术。本文给出了典型的实例，展示了通过机械表面处理提高部件寿命和强度的可能性。一个焦点是材料的性能和近表面塑性变形及其后果的循环变形，裂纹萌生和裂纹扩展过程中的循环加载中创建的微观结构之间的关系。在这种情况下，还讨论了表面层中的微观结构和残余应力的稳定性。
Modern mechanical surface optimization processes today go beyond simple empirical techniques Typical examples are presented, demonstrating the possibilities to increase lifetime and strength of components by mechanical surface treatments. A focal point is the relation between materials properties and microstructures created by near surface plastic deformations and their consequences on cyclic deformation, crack initiation and crack propagation during cyclic loading. In this context, also the stability of microstructures and residual stresses in surface layers is discussed.
