Surface measurement TON Coromant

Surface roughness profile. The R-profile is calculated by using a cut-off filter to remove the long-wave components from the P-profile. The R-profile is therefore an intentional modification of the P-profile. Basis for evaluation. When measuring workpiece surface textures, evaluation is usually based on one specified reference length.

Chrome plating Wikipedia

This etches the work-piece surface and removes any scale. In some cases the activation step is done in the chromium bath. The chromium bath is a mixture of chromium trioxide (CrO 3) and sulfuric acid (sulfate, SO 4), the ratio of which varies greatly between 75:1 to 250:1 by weight. This results in an extremely acidic bath (pH 0).
