Abstract
Thermal barrier coatings (TBCs) constituted by Yttria Partially Stabilized Zirconia (i.e., Y-PSZ, ZrO2 + 7wt% Y2O3) and a metallic bond layer (i.e., MCrAlY where M represents a combination of Ni and Co) are extensively used to improve the performance of hot-section components of gas turbines. Air plasma spray and in situ laser irradiation by diode laser processes are combined to modify thermal and mechanical properties of TBCs. Two types of experiment were conducted to estimate the coating elastic response: Berkovich nano-indentation to evaluate the Young's modulus of the bulk material, and Knoop micro-indentation to evaluate the effective Young's modulus of the coating and its cohesion.
