The authors of the article present nanoparticles impregnation technique developed by Metal Forming Institute (Poznan) for production of sintered powder parts characterised by low friction coefficient at high temperatures. The powder forging of the precision high performance structural components is 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. Presented results relate to sleeve bearing fabricated by the method of forging powder parts impregnated with mixtures of oil and specially developed nanoparticles with desired solid lubricating properties. A proper strain distribution during plastic deformation of particulate material has been achieved by the optimization of the technological parameters. The results of tribological examination of impregnated PM - parts were evaluated to optimize tribological properties of nanocomposites.
