Description

Turbine blades in an aircraft engine are typically made of a nickel-based alloy, and covered with a protective coating to increase oxidation and hot corrosion resistance. The coating is on the order of 50–100 μm thick. There is currently no nondestructive method available to verify that the blade coating thickness is within specifications, or that the proper interfacial boundary has been set up between the coating and base alloy.
