SKODA AUTO introduces plasma-coated cylinder blocks
During the production process, the cylinders are first bored on the machining line. A 1,500-watt laser then abrades the cylinder bores to ensure that the plasma layer will optimally adhere to the surface.
The individual powder grains measure no more than 50 μm. When sprayed onto the cylinder walls, the molten powder forms a layer measuring approximately 250 μm. During final processing, this layer is honed out, so that it measures just 150 μm.
Each cylinder is automatically measured at several stages throughout the process to assess its quality. Optical measuring instruments first record the surface abraded by the laser, before a second measurement is taken once the plasma has been applied.
