The paper gives the results of a series of tests aimed at evaluating the effect of the electrical discharge texturing (EDT) process on the surface integrity of mill work rolls using two different electrical generator and dielectric flushing arrangements. Investigations were conducted using both a Spark Tec dual voltage DC pulse generator and a Charmilles Robofil 200, employing a single high

The thickness of the hard chromium layers was typically 20–25 μm and cracking of the plated layers was clearly evident as a result of high residual stresses. Measurement of surface residual stress using X

Mill rolls finished by electrical discharge texturing (EDT) are widely used in the manufacture of steel and aluminium alloy sheet / strip. Appropriate selection of process operating parameter levels: peak current, onloff time, polarity, etc., allows a limited degree of independence in specifying roll surface topography in tern of surface roughness (Ra), peak count (Pc) and skewness (Rsk), in
