摘要	Pit corrosion susceptibilities of Mg-10Gd-2Y-0.5Zr alloy, AZ91D alloy and pure magnesium were investigated by means of electrochemical noise (EN). The EN data have been analyzed based upon the combined stochastic theory and shot-noise theory. Pit initiation process has been modeled as a nonhomogeneous Poisson process and analyzed using a Weibull distribution function. Pit growth process has been simulated by a nonhomogeneous Markov process and analyzed using Gumbel distribution function. The EN results implied that Mg-10Gd-2Y-0.5Zr alloy had the highest pit initiation rate and pit growth probability, which revealed that Mg-10Gd-2Y-0.5zr alloy had the highest pit susceptibility.
