Understanding the galvanic corrosion of B30 copper-nickel alloy and AISI 304 stainless steel with the effect of fluoride ions and protons using the wire beam electrode
The galvanic corrosion of AISI 304 stainless steel/B30 copper-nickel alloy (304SS/B30 Cu−Ni) was investigated in neutral and acidic solutions with and without fluoride ion (F−) by wire beam electrode techniques, macro-electrochemical methods and scanning electron microscope. The results show that the passivation film was eroded by the synergistic effect of the proton (H+) and fluoride ion on the coupled sample surfaces, leading to changes significantly in the surface electrochemical activity and corrosion rate. The surface morphology after being immersed for 48 h in different solutions was observed by scanning electron microscope. However, 304 stainless steel is used as an anode relative to B30 copper-nickel alloy, with a typical polarity reversal, when fluoride ion is added to an acidic solution with pH=2.0.
期刊介绍：
Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing.
Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline.
Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
