Abstract

A method for the NDE of thermal spray coatings by photothermal imaging is described. The principles of thermal wave interferometry are discussed in relation to spray coatings and it is shown how these can be applied to the detection of adhesion defects and coating thickness measurements. Examples of adhesion defects and thickness measurements in refractory and wear resistant coatings are given.
