Abstract
Current NDI methods cannot detect corrosion onset in painted/sealed aluminum. TRI/Austin's team, including the Applied Microwave Nondestructive Testing Laboratory and Boeing, has successfully used microwave probes to detect 0.08 mm corrosion flaws inprimed and painted aluminum panels covered with aircraft. However, no fieldable microwave systems exist today.TRI/Austin will:1. Make samples with small (down to 25 microns) machined and corroded pits covered by aircraft primers, paints and appliques2. Experimentally refine inspection parameters for field probes3. Design battery powered, handheld microwave probes and
