A story by Engineering.com talks about a collaboration between Rolls-Royce and researchers at Heriot-Watt University to test jet engine turbine blades that are protected from intense heat and wear by ceramic thermal barrier coatings.

The method works by placing a test material under controlled tensile strain and observing changes in the material’s refractive index with a polariscope. The team aims to develop this technique into a setup that can analyze an entire part, providing data to more accurately predict when the part will fail.
