Abstract

Embodiments described herein relate to a non-destructive measurement device measurement device and a non-destructive measurement method for determining coating thickness of a three-dimensional (3D) object. In one embodiment, at least one first 3D image of an uncoated surface of the object and at least one second 3D image of a coated surface of the object are collected and analyzed to the determine the coating thickness of the object.

Description

BACKGROUNDField[0001]Embodiments of the present disclosure generally relate to determining thickness of three-dimensional (3D) object coatings, More particularly, embodiments of the present disclosure relate to determining thickness of protective coatings for turbine blades and other components exposed to corrosive environments.Description of the Related Art[0002]Aerospace components including turbine vanes and blades are fabricated from nickel and cobalt-based superalloys. Superalloy protection during engine operation employs a plurality of layers, including a stable oxide scale that is dense, adheres to the surface or surfaces of the component, and is stable at high temperatures up to about 1900° C. Various barrier coatings, including thermal barrier coatings (TBCs), can be used to inhibit oxidation and corrosion of the aerospace components. Various materials are employed to form these corrosion-resistant coatings, such as native-grown oxides include Cr2O3 for hot corrosion protec...
