1. Introduction to degradation processes. 2. Limit states of technical objects (TO), internal and external factors, classification of degradation processes. 3. Fracture properties of TO materials - introduction. Fundamentals of fractography. 4. TO wear: abrasive, adhesive, erosive, cavitation, vibration - conditions of formation, mechanism, resistance to wear. 5. TO fatigue - basic concepts, initiation, mechanism and propagation of fatigue cracks. 6. TO creep - basic terms, initiation, crack formation mechanism. 7. Degradation by radiation: degradation by UV radiation, radiation damage, etc. 8. Degradation of bearings, rails, pipe systems. 9. Ways of increasing TO resistance to degradation, materials resistant to selected types of degradation.
