This chapter presents an overview of the nature of the surface that results from manufacturing processes, as this nature has long been recognized as having a significant impact on the product performance, longevity and reliability. Surface alterations may include mechanical, metallurgical, chemical and other changes. These changes, although confined to a small surface layer, may limit the component quality or may, in some cases, render the surface unacceptable. A basic understanding of the changes in the condition of the surface is very much required if improvement in product quality is to be attained. Surface integrity (SI) reveals the influence of surface properties and condition upon which materials are likely to perform. It has long been known that the method of surface finishing and the complex combination of surface roughness, residual stress, cold work, and even phase transformations strongly influence the service behavior of manufactured parts as fatigue and stress corrosion.

“…As a result, of these phenomena, the properties of surfaces become poor and unacceptable to fulfill the intended requirements of service. Some examples of components because of surface damages are: (a) environmental stress cracking of plastics by some chemical environments [6], (b) turbine vane and blade material surface deterioration caused by erosion [7], (c) surface corrosion [8], etc. The surface quality of materials therefore greatly needs attention to guarantee a good longevity of manufactured products.…”

316L is a type of austenitic stainless steel that offers a good combination of mechanical properties, corrosion resistance, and biocompatibility. In some industrial applications, it is necessary to proceed to finish treatments to extend the lifetime of the mechanical parts. In the present chapter, ball burnishing treatment is applied to improve the surface integrity of 316L since the performance behavior of parts is directly dependant on the surface properties of the used material. Both surface topography and surface microhardness of 316L after subjection to ball burnishing are studied. The number of burnishing passes is varied by up to five to investigate its effect on the results. Optical profilometer and atomic force microscopy (AFM) were used to analyze the surface roughness and surface topography texture while measurements of microhardness Vickers were proceeded to investigate the changes in surface hardening.
