Method of and apparatus for detecting corrosion utilizing infrared analysis |
摘要 |
A method and apparatus for the non-destructive identification and location of subcoating corrosion on a coated metal surface employing infrared thermography. The apparatus comprises a heat source for directing pulsed infrared radiation onto a test surface; a scanner for scanning the test surface for infrared radiation being emitted therefrom; a detector for capturing said emitted radiation and converting it into a signal representative of the thermal characteristics of the surface; and video display apparatus for visually displaying the signal as a thermal map of the surface. The method comprises the steps irradiating a test surface and detecting temperature differentials that occur on the irradiated surface.
