On the other hand, the standard does not consider the
galvanic couple generated between the worn and unworn areas during sliding either.
Thus, the incrustation of these materials on the carbon steel surface tends to form a
galvanic couple; this is well characterized by the potential values obtained for the plates after the surface cleaning, mainly for the samples from groups D and E.
This suggests that the potential difference generated by the
galvanic couple is greater for the Cu-AA2024-T3 pair than the Cu-Ni-AA2024-T3 pair (Figure 10).
A sampling of topics: the European steel industry's efforts to cut emissions, efforts in India, Canadian green steel, soda fuel cycle metallurgy, and nanoscale
galvanic couples. Neelameggham is a technical development scientist.
