Nondestructive evaluation of corrosion damage of Al-alloys by in-situ AE monitoring and nonlinear elastic wave spectroscopy testing

Significant amount of corrosion damage was revealed during recent complete inspections of airplane structures after years of service. The corrosion damage was located inside airplane’s hull and remained undetected until reaching hull’s outer surface. Therefore a demand for means of timely detection and non-destructive evaluation of corrosion damage arose. This work investigates the possibilitie...

Corrosion Damage Detection with Piezoelectric Wafer Active Sensors

Since today’s aging fleet is now intended to far exceed their proposed design life, monitoring the structural integrity of those aircraft has become a priority issue for today’s Air Force. One of the most critical structural problems is corrosion. In fact the KC-135 now costs $1.2 billion a year to repair corrosion. In this paper, we plan to show the use of Lamb waves to detect material loss in...

On the Evaluation of Texture and Color Features for Nondestructive Corrosion Detection

We present a methodology for automatic corrosion detection in digital images of carbon steel storage tanks and pipelines from a petroleum refinery. The database consists of optical digital images taken from equipments exposed to marine atmosphere during their operational life. This new approach focuses on color and texture descriptors to accomplish corroded and noncorroded surface area discrimi...
