The main aim of this study is to enhance the mechanical properties and microhardness of the surface
of O1 steel using the roller burnishing process. In manufacturing processes, surfaces and their properties are as
important as the bulk properties of the materials. Surface treatment is an important aspect of all manufacturing
processes. It has been used to impart certain physical and mechanical properties, such as appearance, corrosion,
friction, wear and fatigue resistance. Widely used methods of finishing treatment that create necessary parts
with the given roughness usually do not provide optimum quality of the surface. Therefore, methods of Surface
Plastic Deformation (SPD) are used. One of the most effective representatives is the roller burnishing. This can
simply achieved by pressing a hard and highly polished ball or roller against the surface of metallic work
pieces. In this paper the effect of diamond pressing process with a different pressing force (105, 140, 175, 210)
N was studied and the results of the experiments are presented. The major findings of this study are; the true
stress of material has been increased of about 150 MPa, the surface quality has been enhanced by 12.5%, finally
the U.T.S. has been increased by 166 MPa.
