A metal powder containing particles of iron or steel and particles of an alloying element is apt to segregation and dusting. It has now been found that segregation and dusting can be reduced or eliminated if the powder contains a binding agent in solid or liquid state. It is preferred to add to the metal powder one of the agents polyethylene glycol, polypropylene glycol, glycerine, and polyvinyl alcohol, in a quantity of 0.005-0.2 percent by weight. |
