Surface topography effect on galling resistance of coated and uncoated tool steel

► Surface topography considerably influence on forming tools galling resistance. ► Post-polishing improves galling resistance and quality of the formed part. ► If lubricated textured surface postpones adhesion of work material to steel surface. ► Shot-peening has negative effect on friction and galling resistance. ► For coatings, roughness and topography effect on galling depends on coating type.
