CORROSION BEHAVIOUR OF ALUMINUM-NICKEL-IRON ALLOYS IN HIGH TEMPERATURE WATER UNDER DYNAMIC CONDITIONS

Technical Report ·
OSTI ID:4146183

In dynamic corrosion tests in deionized water at 260 C and 20 fps linear velocity, corrosion rates of , hardness, 8 x lO/sup 3/ inchcs/year are obtained for aluminumnickel alloys by using beds containing high areas of aluminum-nickel to saturatc the loop watcr with dissolved corrosion product. Preliminary tests indicate that further reductions in corrosion rate are obtained by giving the test specimens a pretreatment in high temperature static water. Replacement test specimens are observed to eorrode more rapidly than original specimens. Possible mechanisms for these effects are discussed. (auth)
