Effect of roller burnishing on surface roughness of austenitic stainless steel AISI 316L

Abstract EN

Burnishing is a cold working process improves surface roughness, wear resistance, corrosion resistance… etc by introducing residual compressive stress into the surface of the work piece.

In this study burnishing process was applied to machined AISI 316L austenitic stainless steel at two different spindle speed 560rpm and 1030 rpm, with five different depth of burnishing (0.04, 0.08, 0.12, 0.16 and 0.2mm) for two different burnishing time 30 sec.

and 60 sec.

Surface roughness of burnishing surface in addition of reduction in spindle diameter were detected.

The lower surface roughness of burnished surface can be obtained during burnishing austenitic stainless steel AISI 316L with lower spindle speed 560rpm, depth of burnishing equals 0.2mm and 60 second burnishing time.
