A promising solution to prevent cracking in wear resistant coatings due to thermal stresses is to understand and tailor the micro and nanostructure of the coating system. In this work, the thermal cycling behavior of stresses of two coating systems containing TiCN and Al2O3 layers with different microstructure was analyzed using experimental and finite element modeling approaches. The microstructure of the coating system was characterized by electron backscattered diffraction analyses. Stress analysis was performed by in-situ experiments using X-ray Synchrotron radiation in the energy-dispersive configuration. Our study shows that microstructure can significantly affect the behavior of stresses of the coating systems within thermal cycling.
