The shaft becomes provided with a hard chromium coating for
protection against high wear . The chrome layer is evenly thickly and smoothly
deposited on the workpiece surface. The values have to lie in the prescribed tolerance
zone . After the chromium-plating the workpiece can be installed without a mechanical
finish. The most common chromium coatings lies between 5 and 60 µm. Also
small tolerances can be keeped to . This coating method is always advantageous,
when hardness and wear resistance of a workpiece surface is standing in the foreground
. The advantages are also lying at high stability against corrosion. The shaft
consists of the material 1.0503 (C45) .
