美国 Riverton的Hoeganaes公司开发出一种新的Ancordense工艺,它是粉末冶金零件致密化的最重大进展之一。这一新工艺只通过一次压制便可生产出低成本的铁基粉末冶金零件,而且性能优良(高拉伸强度、屈眼强度、延伸率、冲击性能及疲劳强度等)。密度可达到7.2～7.6g/cm~3,这是复压/复烧或渗铜工艺所能达到的密度,而生产成本却要比复压/复烧或渗铜工艺低得多,甚至可与粉末锻造相竞争。 Hoeganaes, Inc. of Riverton, USA, has developed a new Ancordense process that is one of the most significant advances in the densification of powder metallurgy parts. This new process produces low-cost, iron-based powder metallurgy parts with just one press and offers excellent performance (high tensile, optical properties, elongation, impact and fatigue). Density can reach 7.2 ~ 7.6g / cm ~ 3, which is the pressure can be achieved by complex pressure / complex burning or copper infiltration process, and production costs are much lower than the pressure / complex burning or copper infiltration process, or even Competition with powder forging.
