微粉注射成型(PPIM)是一种经济、规模化生产微型零件的常用技术。为了确保较长的使用寿命，要求有较高的耐磨性，而钢制模具比黄铜模具更能满足耐磨性要求。在这项研究中，重点将集中在经过机械加工的Toolox 44试件表面及其下方的特定残余应力状态的发展。
Micro powder injection moulding (pPIM) is a common technique for an economic large-scale production of micro parts. To ensure a long service life a high wear resistance is required which can better be fulfilled by moulds made of steel than by those made of brass. In this study the focus will be on the development of specific residual stress states at and below the surface of a mechanically processed Toolox 44 sample.
