Abstract

The transient anodic behaviour of α-brass in sodium nitrite solution has been studied using scratching and rapid straining techniques. The anodic current and charge densities inferred from the straining experiments are up to two orders of magnitude higher than those measured by scratching. The results show that the rapid straining technique is inappropriate in this environment because the surface film on the brass undergoes a gross mechanical failure when strained. The scratching results are consistent with a film-induced cleavage mechanism of transgranular crack growth.
