Abstract (en)
[origin: WO02079774A2] The invention relates to a method for carrying out nondestructive testing of a gas turbine blade (1) during which corrosion areas (9), which are located near the surface and which consist of oxidized carbides or of base material that is sulfided near the surface, are determined by means of an eddy current measurement. As a result, the blades can be ground or sorted, in particular, before subjecting the gas turbine blades to a complicated cleaning and coating process.
