Method for non-destructive coating thickness measurement in components with complex geometry, involves performing a photo-thermal measurement on basis of phase shift between excitation signals and respective heat-response signals

摘要

The method involves performing a photo-thermal measurement on the basis of the phase shift between excitation signals and the respective heat-response signals as measure for the coating thickness in the respective measuring point. The layer thickness is ranged on the basis of uncoated surfaces and different coating thickness.
