Abstract:
Investigation into the sensitivity to stress corrosion of copper‐nickel‐ palladium alloys 14 Whilst the sensitivity to stress corrosion of the CuNi system is confined to ammonical solutions and to the Cu side, stress corrosion is experienced by the CuNiPd system with 2 to 40% Pd both in FeCl, and in aqua regia in any Cu:Ni proportion. This sensitivity is due to the fact that the noble metal gives rise a markedly electrochemical process cracks and fissures as it forms cathodic zones whilst the bottom of the crack anodically polarized. The time until the crack is formed increases with increasing Ni content, up to Pd contents from 20% onwards. With 3O% Pd and –in aqua regia –from 14% Ni as well as –in FeCl 3 solution –from 21% Ni, no stress corrosion cracking is experienced any longer.
