The electric field distribution of submarine is affected by the degradation of coating properties during service. With material polarization as boundary condition, three electrostatic field models were established by using boundary element method,including submarine coating performance deterioration, coating penetration corrosion and coating local damage polarization. The propeller disturbance electric field model was analyzed from time domain and frequency domain characteristics. The results show that electrochemical polarization state has a significant effect on the potential and harmonic of propeller disturbance electric field. Under the three boundary conditions of constant potential, linear polarization and nonlinear polarization, when the propeller rotates at the same frequency to disturb the electrostatic field, the proportion of frequency components of each model is significantly different. Under the nonlinear boundary condition, the difference between the disturbance frequency and the ratio of twice disturbance frequency is the largest. Under the linear boundary condition, the difference between the disturbance frequency and the ratio of twice disturbance frequency is the smallest. Under three kinds of boundary conditions, the harmonic range of the electric field model above three times of the disturbance frequency will change. The harmonic range of the electric field model is the smallest under the constant potential boundary condition, and the harmonic range is the largest under the nonlinear boundary condition.
