Topic X: Poster Session


Lightweight metals become progressively important in different industries such as automotive or machinery, since their application leads to an energy consumption reduction and thus, an environmental shielding. To tap the whole potential of Al alloys in high-loaded applications, the existing surfaces can be modified by laser texturing in order to increase the energy efficiency by decreasing friction and wear for relevant tribological application cases.

Poly-ether-ether-ketone (PEEK) is a well-known high-performance polymer with high resistivity against corrosion, chemical attacks and wear. Thus, PEEK-based coating systems are supposed to provide low coefficient of friction while keeping the good wear behavior [1]. This study deals with the modification of a PEEK coating system on Aluminum substrates using Direct Laser Interference Patterning (DLIP) [2].

The influence of DLIP structures on the tribological behaviour of PEEK high-performance coatings on Al 6082 is examined by pin-on-disc tests under different lubricated and dry sliding conditions. By choosing an appropriate laser wavelength and suitable laser fluences, DLIP structures with spatial periods below 2 µm could be applied, which improve both – the wear resistance as well as the friction coefficient. Furthermore, the impact on the changed topography and morphology due to the laser structure process is determined by SEM and EDX analysis and correlated to the tribological behavior.
