Mikrotribologie von PVD-Schichten

Transparency of the tribological process by sensory and audio-visual process recording. By multi-media recording of the friction event the elementary contact processes get transparent so that damage causes can be recognized. For this additional to the usual tribological readings audio-visual information were time synchronously gathered. By use of thin integrated sensors temperature or pressure is measured continuously with high local resolution during the friction process inside the contact region. The damage mechanisms are analysed systematically and make influence measures possible to coating optimization to exclude an early failure of a tribological system.
