Abstract

An effect of phosphoric acid on pitting attacks of aluminum A1050 in a formic acid solution has been investigated. Surface observation after corrosion test revealed that the pitting attacks with 10~20 μm diameter occurred when H3PO4 concentration was higher than 100 ppm and temperature was 333 K or more. The anodic and cathodic reactions for the corrosion reaction were thermodynamically determined from E-pH diagrams.
