dc.description.abstract | The article presents the results of an aluminum oxide layer doped with monolayer 2H
tungsten disulphide (Al2O3/WS2) for applications in oil-free kinematic systems. The results concern
the test carried out on the pneumatic actuator operational test stand, which is the actual pneumatic
system with electromagnetic control. The cylinders of actuators are made of Ø 40 mm aluminum
tube of EN-AW-6063 aluminum alloy which is used in the manufacture of commercial air cylinder
actuators. The inner surfaces of the cylinder surfaces were covered with an Al2O3/WS2 oxide layer
obtained by anodic oxidation in a three-component electrolyte and in the same electrolyte with the
addition of tungsten disulfide 2H-WS2. The layers of Al2O3 and Al2O3/WS2 obtained on the inner
surface of the pneumatic actuators were combined with a piston ring made of polytetrafluoroethylene
with carbon (T5W) material and piston seals made of polyurethane (PU). The cooperation occurred
in the conditions of technically dry friction. After the test was carried out, the scanning electron
microscopy with energy dispersive spectroscopy (SEM/EDS) analysis of the surface of the cylinder
bearing surfaces and piston seals of the pneumatic cylinders was performed. The analysis revealed
the formation of a sliding film on the cylinder surface modified with tungsten disulfide, as well as on
the surface of wiper seals. Based on the SEM/EDSM tests, it was also found that the modification
of the Al2O3 layer with tungsten disulfide contributed to the formation of a sliding film with the
presence of WS2 lubricant, which translated into smooth cylinder operation during 180 h of actuator
operation. The cylinder with the unmodified layer showed irregular operation after approximately
70 h thereof. | pl_PL |
