Abstract in different language:	Behaviour of ceramic coatings deposited on steel substrate was tested by cyclic loading and thermal shock. Both tests of ceramic coatings were observed with thermographic camera TIM400. Three different ceramics: Al2O3, Cr2O3 and Cr2O3-5SiO2-3TiO2 were deposited by plasma cascade torch SinplexPro. Relation between temperature and stress and reactions to thermal shocks were inspected. Frequency of 10 Hz, step of 20 MPa and stress ratio R0,1 were used for cyclic load testing. Load was increased every 10 minutes until the specimen fractured. The influence of diverse ceramic coatings on fatigue limit is determined. Thermal shock temperatures were selected based on properties of coating material. To reach desired temperature, resistance heating was used and afterwards compressed air cooled the specimens.
