Influence of ultrasonic burnishing on the surface integrity of planar plates

Ultrasonic burnishing is one of several surface treatment methods. The method a relatively new process used for finishing workpieces to produce good quality. This paper presents ultrasonic as mechanical improving the quality planar plates. improves by increasing hardness workpiece and reducing its roughness. However, it essential know effect on residual stresses in material. study investigated at produced two different materials: AISI 420 steel aluminium (Alumec AA7075-T651). magnitude was examined using an X-ray diffractometer. also evaluated finished workpiece.
