Surface Characteristics of Some Roller Burnished Non-ferrous Components

Abstract

Abstract Burnishing as a cold working process can be used to decrease the roughness of surfaces, and to increase the surface hardness as a result of work hardening. In the present work, a roller type burnishing tool was used to study the influence of the main burnishing parameters on the surface roughness and hardness of commercial aluminum and brass. It was found that roller-burnishing can be used successfully to improve surface roughness and to increase surface hardness. Also, it was found that burnishing force and number of burnishing tool passes are the predominant parameters, for control of surface roughness and hardness of rolled-burnished components.
