AlO/WS Surface Layers Produced on the Basis of Aluminum Alloys for Applications in Oil-Free Kinematic Systems.

The article presents the results of an aluminum oxide layer doped with monolayer 2H tungsten disulphide (AlO/WS) 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.

Investigation of Selected Polymer Composite-Aluminum Oxide Coating Tribological Systems.

The tribotesting of friction systems requires discussion on proper selection of its conditions and data presentation. System tribology is based, for example, on analysis of the friction contact, the roughness of the cooperating surfaces, and the wear rate of the rubbing elements or coefficient of friction in relation to the sliding distance. Friction pairs, consisting of an aluminum alloy sample with an oxide layer (AlO) with and without the addition of inorganic fullerenes like tungsten disulphide (IF-WS) nanoparticles on its surface cooperating with a counter-sample made of polymer composites prepared on the basis of phenol-formaldehyde resin with different fillers, were tested using a device with a pin-on-plate friction pair system.
