| Abstract: |
| Objective The corrosion test of D60 steel, as one of the substitutes of ammunition elements, was carried out in the simulated island environment with high humidity and high salinity. Methods Infrared spectroscopy (IR) was used to characterize the corrosion products. Results The corrosion layer contained adsorbed water. In the initial stage of corrosion, the products mainly included γ-FeOOH and δ-FeOOH, but with the corrosion continued, α-FeOOH appeared in the products, while δ-FeOOH was gradually diminished and finally completely disappeared. In the late stage of corrosion, Fe3O4 emerged. In corrosion events involving Cl-, the corrosion products mainly included α-FeOOH, γ-FeOOH and a little δ-FeOOH. Conclusion The addition of Cl- accelerated the corrosion of the metal matrix. |
