Abstract
The invention concerns a powder metallurgical composition comprising iron or iron-based powder and a minor amount, I.e. o.001-0.2 wt-%, of carbon black. The carbon black acts as flow enhancing agent.
Claims (7)
1. A powder metallurgical composition comprising an iron or iron-based metal powder, a lubricant and/or a binder, and carbon black, wherein the amount of carbon black is between 0.001 and 0.2% by weight, preferably between 0.01 to 0.1% by weight.
2. The powder metallurgical composition according to claim 1, wherein the particle size of carbon black is below 200 nm, preferably below 100 nm and more preferably below 50 nm.
3. The powder metallurgical composition according to claim 1 or 2, wherein the specific surface area is above 100 m2/g, preferably above 150 m2/g and more preferably above 200 m2/g.
4. The powder metallurgical composition according to anyone of claims 1 to 3, comprising additives selected from the group consisting of alloying elements, machinability improving agents, hard phase material and liquid phase forming agents.
5. The powder metallurgical composition according to claim 4 wherein the alloying elements are selected from the group consisting of graphite, Cu, Ni, Cr, Mn, Si, V, Mo, P, W, S and Nb.
6. The powder metallurgical composition according to claim 5, wherein the particles of at least one alloying element selected from the group consisting of graphite, Cu are bound to the iron or iron-based powder particles.
7. Use of carbon black as a flow enhancing agent in iron-based powder compositions.
