Abstract
The invention relates to a metallic work-piece (2, 5, 6, 14, 20, 23) for a hydraulic device (1, 15). The workpiece (2, 5, 6, 14, 20, 23) comprises a coating layer (12), characterized in that the coating layer (12) contains Mo, in particular metallic Mo, with a weight fraction of at least 1%.
Claims10
A hydraulic device comprising a part comprising at least in part a coating layer, wherein the coating layer consists of a weight content of Mo between 80% and 85%, a weight content of Ni between 3% and 4%, a weight content of Cr between 3% and 4%, a weight content of B between 3% and 4%, a weight content of Si between 3% and 4% and a weight content of Fe between 3% and 4%, and wherein the part is movably arranged relative to another part of the hydraulic device.
A part for a hydraulic device comprising at least in part a coating layer, wherein the coating layer consists of a weight content of Mo of at least 1%, a weight content of Fe between 75% and 90%, a weight content of C between 0.5% and 2% and a weight content of Mn between 3% and 7%, wherein the part is movably arranged relative to another part of the hydraulic device, wherein the part is in direct contact or in indirect contact with the another part, and wherein indirect contact means there is a layer of lubricant separating the part and the another part.
