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