烧结零件的力学性能,主要由零件密度、材料组成、材料特性、材料制备工艺等所决定。通过优化材料组成和制备工艺,可以降低零件的综合成本。所谓的新材料新工艺新技术,在零件制造的第一步——原材料,就已经展露出其特有的优势。着重综述了铁基粉末冶金零部件采用的各类原材料,对其力学性能、加工性能、使用性能的应用现状以及发展前景进行分析和探讨,力求探索优化烧结零件性能的有效途径。
The mechanical properties of sintered parts, mainly by the part density, material composition, material properties, material preparation process and so decided. By optimizing the material composition and preparation process, you can reduce the overall cost of the parts. The so-called new materials, new technology and new technology, the first step in the manufacture of parts - raw materials, it has already revealed its unique advantages. The various raw materials used in the iron-based powder metallurgy parts are reviewed. The mechanical properties, processing properties, the application status and development prospects of the performance are analyzed and discussed, and an effective way to optimize the performance of the sintered parts is explored.
