摘要：

Measurements of mass loss from 1 cm(2) of disc made of beta' brass during,a corrosion in air saturated 1.0 M HCl at 30, 40, 50 and 60 +/- 0.1 degrees C have been carried out. At 30 and 40 degrees C dissolution occurs in the activation regime; at 50 degrees C the mixed-kinetics regime is observed while at 60 degrees C the reaction is controlled diffusionally by the oxygen dissolved in the acid. At 30 and 40 degrees C the main corrosion reactions are dissolution with oxygen depolarization and autocatalytic dissolution. At 60 degrees C the autocatalytic dissolution disappears.
