?e development of corrosion- and wear-resistant high-performance coatings is important to improve components of mobile\r\nand stationary turbines, aerospace undercarriages, combustion engines, and hydraulic modules. New micro- and nanostructured\r\ncoating materials and processes to machine these coatings are developed in order to increase the performance of workpieces and\r\ncomponents, to enhance durability, and to reduce maintenance and manufacturing costs. At the Institute of Machining Technology\r\n(ISF), milling and grinding procedures have been developed for the preparation of the workpiece surface for the subsequent coating\r\nprocess. In contrast to conventional applications, the workpieces are not manufactured with the aim of achieving a minimized\r\nresulting surface roughness. Instead of this, a de??ned and adequate structure has to be generated, providing a good adhesion of the\r\nthermal sprayed coating on the workpiece surface. A??er ??rst coating of the prepared substrates by a High-Velocity-Oxygen-Fuel\r\n(HVOF) coating process, the resulting surface topography does not have the required surface quality for a subsequent (Diamond\r\nLike Carbon) DLC coating process. In order to generate a more uniform surface structure, the deteriorated surface resulting from\r\nthe HVOF coating process also has to be processed. ?erefore, the application of an adapted grinding process with diamond wheels\r\nis used.
