ELECTROCHEMICAL CORROSION OF METALS IN CORROSION CELLS WITH CARBON-FIBER-REINFORCED PLASTIC

The bimetallic corrosion behavior of several metals and alloys (such a s carbon and some stainless steels, brass, aluminum, and titanium), wh en in contact with carbon-fiber-reinforced plastics in H2SO4, HCl, H3P O4, and NaOH solutions over wide concentration and temperature ranges and also in simulated sea water at 30 and 50 degrees C, has been predi cted by combining the potential-current-density curves of a carbon-fib er-reinforced plastic (cathode) and a corresponding metal (anode). The predicted behavior was confirmed by the study of corrosion in real ce lls formed by carbon-fiber-reinforced plastic with titanium and alumin um at various surface-area ratios.
