Název v původním jazyce

Characterization of the friction layer formed on the cast iron and stainless steel brake discs during the friction test

Popis výsledku v původním jazyce

Brake disc as a rotating counterpart of the vehicles brake system plays an important role in safe driving. Many papers deal with characterization of the brake lining, representing the static part of the braking tribo-couple. During the contact of the rotating disc and pressed brake lining the friction layer, so called third body, is formed. Cast iron and stainless steel rank among the most often used materials for brake disc manufacturing. The cast iron is often used for cars, whereas stainless steel is often used for the brake discs of motorcycles. In this contribution we focused on the characterization of the friction surface of the cast iron and stainless steel brake discs after the friction test. Non-asbestos organic friction composite was used as a counterpart for cast iron disc, whereas friction composite based on the sintered cupper was used as friction counterpart for stainless steel brake disc. Friction surface of both types of discs were studied using scanning electron microscopy and glow-discharge optical emission spectroscopy. Scanning electron microscope equipped with energy dispersive spectroscopy technique was used for the characterization of the brake disc morphology, as well as for the characterization of the cross section of both discs. Glow discharge optical emission spectroscopy was used for the characterization of the bulk chemical composition of both discs as well as for the profile analysis.
