Abstract
The applicability of the AC Impedance technique to the study of the erosion corrosion behavior of three Cu/Ni alloys was investigated. The experimental simulation of the velocity effect of sea water on these alloys was achieved by using a rotating cylinder in a 3% NaCl aqueous solution. The presence of oxygen or of sulphide or of a combination of these two basic chemicals was controlled as initial examples of interest since these agents are known to affect the nature of the passivating films on Cu/Ni alloys. It was found that the three alloys behave very differently in the presence of oxygen while the addition of sulphide brings the three alloys to the same level of resistance to corrosion.
