A hollow-cast casting is provided, which includes at least one core opening that is caused by the production technique and which has a closure device that closes the core opening. The closure device can be inserted into the core opening axially in relation to the core opening and provides at least one surface region which, in axial projection in relation to the core opening, can be made to abut a surface region of the casting that is facing toward the casting. The surface region lies radially outside a cross-sectional area predetermined by the core opening.

A measuring device for measuring the temperature of a thermally loaded metallic base element, especially a gas turbine component, provided with a protective surface coating includes a sensor integrated in the base element. The sensor is arranged in a recess introduced into the base element from the outside. The protective surface coating is formed continuously over the sensor disposed in the recess.

A method for applying a heat insulation layer () or a metallic protective layer to a thermally stressed component () having a basic material () in order to eliminate local damage () or an untreated place in the coating, includes, in a first step, pretreating the local damage () or untreated place, and, in a second step, applying layers () necessary for eliminating the local damage () or untreated place. A markedly improved lifetime of the processed component can be achieved in that, within the first step, the edge regions () of the layers () ending at the local damage () or untreated place are processed so that they form uniformly sloped and terrace-shaped edge regions (). Furthermore, a precharacterization of the entire coated region of the operationally stressed component or critical places by FSECT makes it possible to reduce the risk in terms of otherwise overlooked layer regions, the remaining lifetime of which would not persist for the following operating time.
