In recent years powder metallurgy method P/M because of complicated parts production ability is used widely, but existence of porosities in this products will decrease mechanical properties in this method, but advanced powder metallurgy methods like powder forging P/F with having profits of powder metallurgy P/M because of visible reduce in porosities will decrease powder metallurgy problems. One of the mechanical properties that is effected by the porosity is wear properties ,in this research by comparison between two groups of specimen, that first group made by powder metallurgy method that had 14% amount of porosities and second group that made by powder forge method P/F that had less than 1% amount of properties and change in wear parameters in both of groups we survey wear properties and we compare wear rate and mechanism result is showing visible relation between wear properties and amount and morphology of porosities.
