White Layer Removal

A brittle layer, commonly called the white layer, is found on the surfaces after nitriding and should be removed from running or bearing surfaces. The depth of the white layer depends on the precise nitriding cycle and the depth of nitriding used.

SWMFs white layer removal can be effectively applied to a wide range of components types, sizes, and metals.
