Mechanism and effectiveness of inhibitors for SCC in a caustic environment

Description
The effectiveness of inhibitors for stress corrosion cracking (SCC) of alloy 600 steam generator tubes exposed to caustic solutions was evaluated. Mill annealed material was exposed as C-rings to solutions at 320 C at open circuit and while polarized at 100, 150, and 200 mV above the corrosion potential. In pure 50% caustic and caustic with boric acid, specimens polarized at 150 and 200 mV cracked through-wall in less than two days. Certain Ti compounds, cerium salts, and Zn compounds increased resistance to SCC. An evaluation of results from surface analysis and from electrochemical measurements provide a mechanistic explanation for the beneficial effects
