Accelerated Corrosion Test Spectrum of Typical Reef Atmospheric Environment

Objective To study on the interior accelerated corrosion testing methods for weaponry in typical reef atmospheric environment. Methods The main environmental factors which caused corrosion damage to weaponry were obtained by the gray correlation analysis method. The reef atmospheric environment spectrum was complied based on the analysis of reef corrosion environment data which weaponry was faced in service. The equivalent conversion relationship between accelerated corrosion test spectrum and reef atmospheric environment spectrum was established according to the accelerated theory and measured convert coefficient of equivalent corrosion. Results The compilation method of interior accelerated corrosion test spectrum was concluded, and accelerated corrosion testing spectrums which faced to the reef atmospheric environment of materiel service were obtained. Conclusion The interior accelerated corrosion test spectrum and accelerated relationship are determined. It provides important evidence for material selection and structure corrosion life evaluation of the ground or deck weaponry.
