Subject syllabus:
1. Materials used for automobile disc and drum brakes - groups of components
and their functions, production of materials for automotive braking
systems, properties and composition trends for individual types of vehicles.
2. Car braking - material changes in braking systems that occur in friction
processes due to temperature and pressure. Friction layer formation and its
influence on friction efficiency of brake system materials. Abrasion of
brake system materials, formation of wear particles and their influence on
the service life of individual components of the brake system.
3. Methods of testing friction abrasion properties of materials for brake
systems - laboratory tribometers, brake dynamometers, operational tests -
test setup, standard test procedures, demonstration of data obtained by
individual methods and interpretation of experimental data from individual
test methods.
4. Behavior of braking system materials under different conditions of
operation - high braking system temperatures, air humidity, presence of
road salts, etc. - changes in brake system materials due to driving style,
environmental conditions and differences in individual friction composite
groups (metal, organic, ceramic).
5. Abrasion particle emissions - mechanism of origin, character, methods of
measurement and characterization of chemical composition and particle
morphology.
6. Emissions of gaseous substances - mechanism of formation, methods of
measurement and characterization - emission of inorganic gases, volatile
organic compounds and their possible risks.
7. Trends in the development of environmentally friendly materials -
substitution of some hazardous components of friction composites, additives
in friction composites and coating of brake discs to reduce abrasion
particles emissions, abrasive particles trapping device and others.
8. Legislative framework of issues of emissions from non-combustion processes
in transport - upcoming legislation for control and regulation of dust
particles emissions.
