Anodic characteristics and stress corrosion cracking behavior of nickel rich alloys in bicarbonate and buffer solutions
The aim of this work is to investigate which alloying element in C-22 is responsible for the cracking susceptibility of the alloy in bicarbonate and two buffer solutions (tungstate and borate). Six nickel based alloys, with different amount of chromium (Cr) and molybdenum (Mo) were tested using elec...
