“…Lumsden [2] suggested that the Ti additives improved the SCC resistance of Alloy 600 due to a change in the composition and the structure of the duplex oxide film, and a passive layer plays a critical role in SCC resistance. Our previous research showed that an addition of TiO 2 changed the electrochemical property of Alloy 600 [6]. The active current density peak and the current density in the active/passive transition are decreased, and the passive range is extended by TiO 2 .…”

Several chemicals were studied to suppress the damage due to stress corrosion cracking (SCC) of steam generator (SG) tubes in nuclear power plants. The polarization curves showed that the electrochemical properties on the surface of Alloy 600 MA changed with the addition of inhibitors. The SCC tests were conducted by using a m-RUB specimen in a 10% NaOH solution at a temperature of 315°C. The effects on the SCC of the compounds, TiO2, TyzorLA and CeB6, were tested for several types of SG tubing materials. The test with the addition of TiO2 (P25) and CeB6 showed an effect in decreasing the SCC for the SG tubing material. However, CeB6 caused some more SCC for Alloy 800. The penetration property into a crevice of the inhibitors was investigated by using Alloy 600 specimens with different gap sizes and an AES analysis was performed on the oxide layer of the specimen.
