Abstract:
1. A method for detecting defects in coatings comprising the operations of: a) applying a plurality of paint process coatings to a surface, wherein the paint process coatings relate to a painting process; b) assigning a thermal effusivity value to each of said paint process coatings; c) configuring an expected change of temperature for said paint process coatings based on said effusivity values for each of said coatings; d) manipulating the temperature of said surface and paint process coatings; e) measuring the change of temperature in said manipulated surface and paint process coatings; and f) comparing said measured change of temperature in said manipulated surface and paint process coatings to said expected change of temperature so as to detect a defect in said paint process coatings on said surface based upon said effusivity values.
