Prediction of Equipment Corrosion Amount in Marine Atmosphere Environment

Aiming at the problems of equipment corrosion affecting combat readiness time and technical integrity, a prediction method of equipment corrosion residual life is proposed. Based on the influence of marine atmospheric environmental factors on equipment corrosion, combined with the power function equation of metal atmospheric corrosion amount with time, the environmental equivalent spectra in different environmental characteristics are established. According to the accelerated corrosion conversion method and the equivalent principle, a model is used to predict the corrosion life of equipment in the actual marine atmospheric environment by using the accelerated corrosion of laboratory environment. The results show that the model has good fitting effect and certain reliability.
