Abstract
Strategic stainless steel surfaces have been developed by which the tribological properties
are significantly improved for sheet metal forming compared to as received surfaces. The
improvements have been achieved by modification of the surface in order to promote
micro-plasto hydrodynamic lubrication by increasing the ratio of closed lubricant pockets
and modifying the pocket geometry. These factors influence the retention and
subsequently escape of lubricant during forming thus enhancing lubricant permeability to
the contact between flattened work piece asperities and contacting tool. The technique,
which has been developed, is based on an electrochemical treatment changing the
topography of the stainless steel surface. Comparative testing of the new surface
topographies in ironing and deep drawing of stainless steel sheet shows significant
improvements and possibilities of replacing chlorinated paraffin oils with environmentally
friendly, plain mineral oil.
