Abstract
A method for non-destructive evaluation of an article of manufacture () by coating the article with a temperature-sensitive coating (), stimulating the article with energy () to induce temperature changes in the article responsive to features of the article, then evaluating () a resulting topography of energy-induced changes () in the coating (). The energy imparted to the article may be, for example, electromagnetic, magnetic, or sonic energy that produces localized changes in temperature in the article () in response to features () of the article such as flaws or other discontinuities. The coating () may be a suspension of liquid crystals in a liquid, and the energy may be an application of sonic energy. The coating may be a material that hardens () or softens () upon a slight increase in temperature. Layers () of different energy-sensitive coatings () may be applied to indicate different aspects of features of the article.
