Equivalent Accelerated Corrosion Test of 2A12 Aluminum

Based on an environmental spectrum of certain area, 2A12 was used to prepare for simulation pieces. Part of simulation pieces were hanged on the escort plane while accelerated environment corrosion test were carried out under laboratory. Microscopes were used to detect and measure the corrosion morphology. The results showed that the accelerated corrosion and the natural aging corrosion were consistent at the confidence level of 95% while time matched.
