  • Method of determining the appearance of losses of cohesion in a transparent ceramic coating layer formed on a substrate
    Patent number: 9599568
    Abstract: A method of determining the appearance of losses of cohesion in a transparent ceramic coating layer (16) formed on a substrate (10), the method comprising the steps that consist firstly in looking for an image representative of a separation zone, if any, between the ceramic layer and the substrate, and secondly in analyzing the detected image, if any, with the image being viewed optically at particular wavelengths that are greater than or equal to 500 nm.
