AB  - In load-following power plants it is necessary to adjust the electrical output to the demand within adequate time. When a steam turbine is used in a load-following power plant the availability of the plant is mainly limited by the thermal cycling behaviour of the steam turbine. Thermal barrier coatings (TBCs) offer the potential to increase the operational flexibility of steam turbines. When applied to a turbine, TBCs may alter the temperature regime of components in a way that enables to shorten the start-up / shut-down procedure. Such an improvement would make load-following steam power plants more flexible in terms of electricity output. In the present study the suitability of atmospheric plasma sprayed thermal barrier coating systems for steam turbine applications was investigated. Coating systems consisted of a metallic bondcoat for oxidation protection, a ceramic TBC for thermal insulation and a metallic topcoat for erosion protection. The substrates on which the coatings were applied were ferritic / martensitic 1
