Cylinder Drum of a Hydrostatic Axial Piston Machine having a Wear-Resistant Layer

摘要

A cylinder drum of a hydrostatic axial piston machine has a plurality of cylinder bores formed in the cylinder drum. A respective piston is moved in each of the cylinder bores in a manner subject to intensive wear. The cylinder bores are nitrocarburized in a salt bath or in gas to minimize the wear and include a thin uniform connecting layer that has a thickness of 4 to 16 μm and a comparatively thick underlying diffusion layer.
