PULVERZUSAMMENSETZUNG MIT AGGREGATEN VON EISENPULVER UND ADDITIVEN UND FLUSSMITTEL UND HERSTELLUNGSVERFAHREN DAFÜR

摘要

The present invention concerns powder compositions including iron-containing powders, additives, lubricant and flow agents. The powder compositions essentially consist of iron-containing particles having additive particles bonded thereto by a molten and subsequently solidified lubricant for the formation of aggregate particles and from about 0.005 to about 2 percent by weight of a flow agent having a particle size below 200 nanometers.
