Friction and wear of hydraulic cylinders with coated piston rods and piston guides

摘要

The behaviour of hydraulic cylinders is decisively influenced by friction and wear of sealings andguides. Friction forces and wear can be reduced with coatings applied by processes like ThermalSpray Technology or Physical Vapour Deposition. This paper shows results of tests with differentkinds of coatings. The parts of the tribological systems are investigated with varying traverse forcesand working pressures.
