Pyramidal asperities of different apical angle were machined on a flat copper surface. Hardness was estimated from the load–displacement graphs obtained by pressing a spherical rigid indenter onto the asperities. The variation of hardness with apical angle and pitch was recorded with a view to contributing to the development of a general framework for relating measured hardness to the surface roughness.
