A method for checking a component to be produced in an additive manner, having the steps of mechanically exciting at least one additively constructed layer of the component during the additive production of the component, measuring a mechanical response signal of the component, and displaying a warning and/or interrupting the additive production of the component if the mechanical response signal lies outside of a specified tolerance range. A device for the additive production of a component, includes a device for mechanically exciting the at least one additively constructed layer of the component, a measuring unit for measuring the mechanical response signal of the component, and a control unit. The control unit is designed to display the warning and/or interrupt the additive production if the mechanical response signal lies outside of a specified tolerance range.

A shipment packaging for elongate components is provided. Turbine blades must be sent from remote locations of the world to another location. During shipment, the coating of the turbine blades must be protected. The turbine blades are fixed at both ends by means of shipment packaging so that the turbine blades are protected.

A method for determining the roughness of an internal surface of a metal substrate or a metal layer is provided. By the correlation of a single destructive measurement in order to determine the roughness and the conductivity measurement of a transition region, the roughness is determined for other samples without destructive measurement.

A method for determining and evaluating eddy-current displays, in particular cracks, in a test object made from an electrically conductive material is provided. The method uses the following steps, applying an alternating electromagnetic field of a predetermined constant or variable frequency to the test object, detecting the eddy currents induced in the test object along predetermined parallel measuring tracks, providing eddy-current signals each eddy-current signal is assigned to a measuring track, conditioning the eddy-current signals and providing conditioned measured variables, interpreting the conditioned measured variables using a predetermined evaluation algorithm, and providing synthetic crack signals.

A method of repairing a crack in a component comprising a base material, in particular in a gas turbine blade, a suspension, which comprises a carrier liquid and at least one solid in the form of nanoparticles of the same material as the base material, being applied to the location to be repaired. A heat treatment of the component is carried out, the solid in the form of nanoparticles being melted and a bond with the base material being formed. During the heat treatment, the component is exposed to a thermal shock, in which a maximum temperature which corresponds to the melting temperature of the nanoparticles is reached. The nano size of the particles in the suspension causes a lowering of the melting point of these particles to take place, so that the structure of the base material does not change even at the melting temperature of the nanoparticles.
