Abstract
A turbine blade with a ceramic thermal barrier coating system has a substrate designed as a blade platform and as a blade airfoil. On the substrate is a first ceramic layer as a thermal barrier coating, which protects the substrate in the exposed high temperature region and there is locally an increase of the thermal barrier coating for locally reinforcing the thermal barrier. The increase includes a material that is different from the material of the first ceramic layer. The local reinforcement is arranged over the first ceramic layer, without the first ceramic layer having a reduced layer thickness. The local reinforcement is provided at most on 30% of the area of the blade airfoil and is arranged close to a platform extending over the entire pressure side in the direction of flow and with an extent thereto in the radial direction of the blade airfoil is at most 30%.
