Abstract
The present invention concerns a method for producing powder metal parts having a densified surface. The method comprises the steps: - compacting an iron-based powder by high velocity compacting technique to a density above 7.2 g/cm<3> - sintering the parts -subjecting the parts to a surface densifying process.
