Current developments in machine building and automotive industry are dealing with the amplification of energy efficiency and sustainability of components. Therefore, a possible approach is function integration, which enables the application of different functions on one component. A further aspect of energy saving by mass reduction can be taken into account by substituting steel by lightweight metals. But in most of the application cases the requirements exceed the properties of the base materials. To overcome this mismatch, multifunctional, application-adapted coatings are required.

In this study the development of a multilayer approach is presented, where PEEK (poly-ether-ether-ketone) is used as a base coating material for Al substrates. The coating is applied by using laser radiation to increase the energy efficiency of the coating process on the one hand and to reduce thermal stress on the component on the other hand. Furthermore, the laser process improves the mechanical properties of the polymeric coating.

In the first step the correlation between laser power, interaction time, scan strategy and the resulting coating morphology accompiened by its mechanical properies was elucidated. Here, additives and their variable concentrations lead to different process parameters resulting in different behaviour of the coating under dry sliding conditions (see Figure 1).

Utilizing these findings, the laser process for each disperion could be optimized, and a multilayer system was established, which combines high corrosion and wear protection accompanied by a tribofilm formation resulting in low friction and an increased lifetime of the coating system.

The experiment work of this study is based on SEM and EDX analysis in combination with tribological measurements, which are related to the laser parameters of the coating process and the interaction of the additives with the laser radiation.
