The technologies of powder metallurgy provide vast possibilities of forming powder products with desired mechanical, physical and service properties. Considering cost minimization, an important advantage of those technologies is low specific energy consumption in serial and mass production, as well as almost wasteless production process.The authors of the article present methods of production of sintered powder parts developed in the Poznań Metal Forming Institute and discuss research results. The powder forging of the precision high performance structural components are of great importance to achieve a definite material density. This study is focused on deformation PM- parts. e.g. sleeve bearing during precision cold forging. The results presented relate to sleeve bearing made by the method of forging powder parts impregnated with oil-solid lubricant mixtures. A proper strain distribution during plastic deformation of the particulate material has been achieved by the optimization of the technology parameters. The results of the impregnation examination were evaluated from the viewpoint of optimization of tribological properties of composites.
