Analysis of the effect of lifetime increasing environment friendly burnishing process on surface micro-hardness

Abstract

Different surfaces that are machined by conventional processes such as turning and milling have inherent irregularities and defects like tool marks and scratches which cause energy dissipation (friction) and surface damage (wear). In contrast burnishing process is a kind of chip-less environment friendly technique that improves the surface integrity obviously. In this study I examine the effect of this life-enhancing surfaces strengthening method on surface micro-hardness on low alloyed aluminium components. To planning and executing the experiments I use full factorial experimental design method and the measurement of the surface micro-hardness of the specimens was done with a Wilson Instruments Tukon 2100B measuring equipment.
