METHOD OF MAKING LUBRICATED METALLURGICAL POWDER COMPOSITION

摘要

A method is provided for incorporating lubricant and a sintering aid into a metallurgical powder composition of iron-based powders. A particulate iron-based powder is contacted and wetted with solution of a metal salt of a fatty acid in an organic solvent. The solvent is removed to provide iron-based particles having a coating of the metal salt. The resulting self-lubricated powder composition can be compacted and sintered to produce a compact having superior strength properties.
