摘要	In this work, the change of Young's modulus, hardness, and bending strength of air plasma sprayed ceramic coating systems after different thermal shock was investigated by nanoindentation tests and three-point bending tests. The results of these tests show that the Young's modulus and hardness of nanostructured coatings and the bending strength of nanostructured coating-substrate systems fluctuate relatively slightly as the thermal shock temperature difference increases, while the Young's modulus and hardness of micro-structured coatings and the bending strength of micro-structured coating-substrate systems increase with the thermal shock temperature difference monotonously. Therefore, in the temperature range we studied, the mechanical properties of nanostructured coatings are less sensitive to the change of temperature and more stable than micro-structured coatings.
