| Abstract: |
| Objective To determine the equivalent accelerated relationship of local environment spectrum. Methods A semi closed key part of an aircraft was researched. Environment spectrum of local accelerated corrosion test was compiled based on its location in the plane and climate conditions of the service environment to carry out laboratory immersion corrosion and environmental exposure respectively: Test pieces of two different environments were tested for performance according to general performance test on macro and micro topography detection, color difference, gloss and other properties. Results Accelerated corrosion of cycle immersion in library for 196.6 hours was equivalent to parking on the ship surface for 1 year. The coating morphology, light loss rate, color difference, and electrochemical performance of two cycles of accelerated corrosion in laboratory were consistent with two years of natural exposure. Conclusion The equivalent accelerated relationship of the local environmental spectrum is accurate and reliable. |
