In this article, polished specimens are peened employing water jet pressures in the range of 100 MPa-300 MPa. The performance of peened specimens has been evaluated by examining the sliding wear, using pin-on-disc type wear testing machine. The performance of water jet peened specimens is compared with that of polished specimens in order to demonstrate the effectiveness of water jet peeningfor surface treatment.
