The results showed that cathodic current density was controlled by the unsteady state diffusion step in the early period of CP, which made the required cathodic current density larger than that for the bare cast .
结果表明，带锈铸铁阴极保护初期的保护电流密度大小受非稳态扩散步骤控制，使得保护初期在较长时间内需要很大的保护电流密度，直到趋于稳定后，它才接近于相同条件下裸铸铁所需的保护电流密度大小。
