  • Electromagnetic probe testing of bond coat
    Patent number: 11143620
    Abstract: A method for measuring a non-magnetic coating thickness upon a non-magnetic gas turbine component, such as a hot gas path component, can comprise applying a magnetic coating, such as a ferrous coating, upon the non-magnetic gas turbine component, applying a non-magnetic coating, such as a metallic bond coating, upon the magnetic coating, and measuring a thickness of the non-magnetic coating with a magnetic induction probe. The magnetic induction probe can be calibrated to the magnetic coating before the non-magnetic coating is applied. Measuring of the thickness of the non-magnetic coating can be used to validate spray patterns of automated spray processes. The magnetic and non-magnetic coatings can be stripped from the gas turbine component and used to validate additional spray patterns.
