Feasibility of Ultrasonic Rayleigh Waves for the Detection of Corrosion Beneath Paint.
Abstract
Rayleigh waves of ultrasonic frequency were investigated as a potential tool for detecting corrosion beneath paint on Naval ships. In certain cases, the method did detect corrosion, but in other cases known pockets of corrosion could not be detected at all. Most important, it was found that the paint is extremely attenuating to Rayleigh waves and that inspection distance is effectively limited to a distance of about twelve inches. For these reasons, Rayleigh waves were not considered either practical or reliable as a tool for detecting corrosion beneath paint. (Author)
