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.

    Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
