摘要 |
A process for producing a mixed powder for powder metallurgy in which graphite segregation can be prevented and which has satisfactory flowability and brings about satisfactory lubricating properties, the process comprising: selecting an organic binder which, when the solubility of an organic lubricant in a given organic solvent at a given temperature is taken as 1, has a solubility in the same solvent at the same temperature of 2 or higher; mixing the organic lubricant and the organic binder with the given organic solvent together with an iron powder to prepare an iron-powder slurry in which the organic lubricant and the organic binder have been dissolved in the organic solvent; and removing the organic solvent from the iron-powder slurry by vaporization to precipitate the organic lubricant and the organic binder in this order. |
