Abstract
The present study presents an applicability of surface plastic flow process consisted from a shot peening and a burnishing as a surface modification for decrease and stabilize of friction resistance. Aluminum alloy (5056) disc used for the specimen was shot-peened to penetrate molybdenum disulfide (MoS_2) then was burnished with cemented carbide roller. The disc specimen fabricated micro dimples in advance to the M0S2 penetration was prepared. The tribological properties of the treated surface was evaluated with a ring on disc type testing apparatus in lubricated condition. As results, significant decrease of the friction resistance was found on the burnished surface fabricated the micro dimples in advance to the MoS_2 penetration.
