Metal-ceramic surfaces
Modifying light metal surfaces
Up to now, equipping metal-ceramic surfaces of light metal components with defined properties has only been possible within narrow limits. With Metaker Surface, Automoteam is presenting a technology based on the MAO principle (Micro Arc Oxidation), but with fundamental differences in the work processes.
The term "metaker" is made up of "metal" and "ceramic" and refers to the electroplasma-chemical production of a metal-ceramic surface with a layer thickness of 2 to 200 µm on light metals such as hypoeutectic aluminum alloys, magnesium or titanium.
The Metaker processes transform the microstructure of the workpiece in the surface layer area into a multifunctional gradient material, which can have different chemical, physical and optical properties depending on the process. In addition to very good topological properties, the modified surface is significantly more temperature-resistant than the alloy of the workpiece. For electronic applications, the adjustability of the thermally conductive layer as electrically conductive or dielectric is of extraordinary interest. The surface can also be printed. Both features are important for the production of high-quality circuit boards with conductor tracks and circuits, for example.
Generatively produced light metal components can also be modified using the Metaker process. This enables applications that combine the weight and geometry advantages of generatively produced light metal components with the performance of multifunctionally modified light metal surfaces. cs
