| Abstract: |
| Objective To study the outfield detection techniques for corrosion damages of aircraft. Methods Several experimental investigations were carried out to detect the corrosion damages of Al alloy and structure steel using three newly developed NDT techniques including X-radial CR, X-radial DR and infrared thermographic detection. Results X-radial CR detection technology could detect hidden corrosion damages of monolayer and crack damages of multilayer Al alloy and structure steel. X-radial DR detection technology could detect hidden corrosion/ crack damages of monolayer or multilayer Al alloy and structure steel. Infrared thermographic detection technology could only detect hidden corrosion damages of monolayer Al alloy and structure steel. Conclusion X-radial DR detection technology could effectively detect hidden corrosion/ crack damages of monolayer or multilayer Al alloy and structure steel, which was considered to be prior to X-radial CR and infrared thermographic detection technology in outfield detection of corrosion damages of aircraft. |
