摘要
FLOMET工艺是一种粘结剂-处理混合技术,其是用固态有机粘结剂将细小的石墨粉、金属添加剂及润滑剂颗粒粘结在较粗的铁粉颗粒上。和常规混合粉相比,粘结剂-处理混合粉的主要好处是,流动性较好,可提高生产率与零件的一致性,以及减小扬尘(dusting)与偏聚。这些特性都使粘结剂-处理的混合粉很适于生产高性能粉末冶金制品,以及其他各种用途需要优异充填特性的混合粉。QMP在20世纪90年代中期提出了一系列粘结剂-处理的混合粉。此后,为改进这类混合粉的性能和开发能用于特殊用途的粘结剂-处理混合粉一直在进行不懈的努力。本文评述了粘结剂-处理材料的物理性能,生坯与烧结体的性能。特别关注的是这些材料的生产工艺特性。
FLOMET technology is a binder treatment blending technique that consists of bonding fine particles of graphite, metallic additives and lubricants to the coarser iron particles using a solid organic binder. The main advantages of binder-treated mixes compared to conventional mixes are better flow, improved productivity and part consistency and reduced dusting and segregation. These attributes make binder-treated mixes well suited for high performance PM applications as well as other types of applications requiring mixes with excellent die filling characteristics.
QMP introduced a family of binder-treated mixes in the mid 1990's. Since then, R&D efforts were pursued to continuously improve the properties of this type of mix and to develop better performing binder-treated mixes for specific applications. This paper reviews the physical, green and sintered properties of binder-treated materials. Particular attention is paid to the processing characteristics of these materials.
