Abstract
The invention is to structure the stator housing with a laser-based structuring process to improve the adhesion of the rubber. In contrast to other laser based structuring processes using expensive pulsed laser sources, inexpensive continuous wave lasers are used for this application. The laser beam should be guided by fibers to ensure an easy handling of the laser light. Preferable high quality (single mode) laser sources with a wavelength between 1,064 nm and 1,070 nm shall be used to ensure the formation of structures with a high aspect ratio. The structures might be a helical continuous lines. The device for the laser structuring is inserted in the stator and moves continuous along its length. The structures are made on plain stator walls as well as complex stator geometries.
