Optical method to pinpoint weak spots in jet engine thermal coatings

For the first time, researchers from Heriot-Watt University, Edinburgh, have demonstrated that an optical analysis method can reveal weak areas in ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. The technique could be used to predict how long coatings would last on an airplane and might eventually lead to new thermal barrier coatings, making engines more efficient and cutting both the cost and pollution of air travel.
