Abstract
The influence of nitrogen dioxide, NO2, and ozone, O-3, on sulfur diox ide-, SO2-, induced atmospheric corrosion of nickel has been investiga ted through combined laboratory and field exposures. Both types of exp osures result in corrosion products with nickel(II) sulfate as the mai n constituent. NO2 accelerates SO2-induced corrosion significantly mor e than O-3 and the results suggest that a mixture of SO2 and NO2 in pr oper concentrations can simulate the atmospheric corrosion behavior of nickel in a broad range of environments.
