Physical Sciences Inc. (PSI) has been awarded a contract from the U.S. Navy to develop a novel technology for non-destructive imaging through paint or epoxy coatings on naval air vehicles to detect subsurface defects and corrosion.
Undetected corrosion can lead to serious functional and structural failures with consequences that include the risk to the safety of persons, damage to the equipment and environment, and economic impacts. Early detection of corrosion and related defects is critical, as it would reduce the remediation cost, improve the operational safety, and minimize mission downtime of fielded assets. Unfortunately, traditional methods for detecting corrosion defects are inefficient, and involve costly removal and replacement of the coatings and paints for visual inspection of the underlying surface. Removal and replacement of these polymer or painted sections involve costly operations in terms of labor and materials costs. To address this need, Physical Sciences Inc. proposes to develop a novel non-contact optical imaging technology, which will use mid-infrared radiation (~ 4 um) to penetrate paints and resins and examine sub-surface material quality and presence of corrosion.
