Comparison and study of the corrosion differences of bronze alloys in oxygen-free and oxygen-containing conditions
Source abstract
Abstract
The study on the initial corrosion of duplex bronze alloy by dissolved oxygen in Cl -containing environment showed that bronze alloy was preferentially passivated in aerobic environment, and then Cu selectively dissolved. The corrosion rate first slowed down and then gradually accelerated. In contrast, the oxygen-free environment accelerates the reaction of Cu-Cl and Sn-Cl, forms a Cl - rich layer on the metal surface. This layer promotes the formation of Sn chloride, thereby inducing the stratification of Cu-Sn products. In this process, the acidification of the solution causes the metal to enter a self-circulating corrosion mechanism, but the corrosion rate remains low.
