Developed as a U.S. Small Business Innovation Research (SBIR) project, the Corrosion and Coating Evaluation System (CorRES) aims to accelerate the screening, quali‡cation, and implementation of new aircraft coatings, according to scientists at the Air Force Research Laboratory (AFRL) (Wright-Patterson Air Force Base, Ohio, USA). 1 Unlike conventional coating tests that rely on an expert's visual evaluation of a test panel, the CorRES system takes measure- ments throughout a coating's test and transmits data in real time to a base station for evaluation.

"By better understanding the corrosion performance of materials we put on an air- craft, we can help control corrosion costs and enable smart maintenance," says Chad Hunter, the team lead for corrosion and erosion in the systems support division at the AFRL's materials and manufacturing directorate. "Corrosion maintenance costs are more than $5 billion a year for the Air Force, so if we can better understand a material from the start, we can enable smart maintenance and ultimately reduce costs throughout the lifecycle." According to the Air Force, aircraft coat- ings are the ‡rst line of defense when it comes to mitigating the structural corro- sion of an air platform. As new coatings are developed, particularly those containing non-chrome primers, AFRL researchers say material quali‡cation tests are essential. Use of Sensor Panels To address this challenge, the CorRES system measures the ability of coatings to protect aircraft structures using sensor
