And the inclination of sacrificial anode corrosion is smaller relatively after two days of the experiment because the sacrificial anode surface is covered with corrosion products.
Chemical polarization results from a thick film forming on the anodes, which results in poor anode corrosion. Typically, one sees a thick sludge-like film form on the anode.
Anode corrosion appeared to be much faster with this type of bath, and to combat this effect the lead/tin anode was introduced.
It showed that the change of ambient temperature had little effect on the degree of sacrificial anode corrosion with the influence of DC stray current, but there was also a certain rule.
It indicated that the change of chloride ion concentration had great effect on the degree of sacrificial anode corrosion under the influence of DC stray current.
The sacrificial anode corrosion under DC stray current of 3 V mitigated.
It indicated that the degree of the sacrificial anode corrosion increased with the rising of the temperature.
It indicated that the higher the chloride ion concentration was, the faster the sacrificial anode corrosion rate was.
It indicated that the sacrificial anode corrosion rate was faster with DC interference.
The change of resistance of sacrificial anodic oxide film was greater with the increasing of temperature, indicating that the increasing of ambient temperature promoted the production of corrosion products at the sacrificial anode surface and reduced the resistance of sacrificial anode surface corrosion reaction and then accelerated the sacrificial anode corrosion. However, the change of temperature had little effect on the change range of the oxide film resistance, indicating that the temperature had little effect on the performance of the sacrificial anode.
It could be seen from Table 8 that the solution resistance at 0% chloride ion concentration was larger than that in the presence of chloride ion at the same time, indicating that the sacrificial anode corrosion rate was very slow at this condition.
