Paper Title:
Influence of SO2 Concentration on Initial Corrosion of Aluminum in Marine Atmosphere
  Abstract

Influence of SO2 concentration on initial corrosion of aluminum was studied in simulated marine atmosphere. Variation of initial corrosion morphology, relation between weight gain and time in the course of initial corrosion, corrosion speed (token with maximum pitting depth and weight gain) were analyzed and discussed. Primary results is list below: In marine atmosphere, SO2 sedimentation above 0.1 mg/100cm2 can accelerate Al pitting with low Cl- sedimentation. Both corrosion weight gain and pitting depth increase obviously. For pitting surface of LY12 with SO2 and Cl- sedimentation, corrosion potential change little, Nyquist Graph was single arc of capacitance resist with retractile real part, Rr can’t reflect corrosion degree.
