| Abstract: | As a model experiment for the corrosion behaviour of brazed joints in water pipes made of stainless steel, some tens of an broad joints made of three different brazes (Ag/Cu/In/Ni, Ag/Cu/Sn, Ag/Cu) were exposed to streaming water at different Cl– concentrations. The samples were polarized. The three-dimensional distribution of the corrosion products, obtained by Auger mapping and depth profiling, supplied some information about the corrosion behaviour of the joints. |
