Abstract
CORROSION IN HIGH PURITY, LOW CONDUCTIVITY WATER WILL BE INVESTIGATED BY ELECTROCHEMICAL METHODS INCLUDING POLARIZATION RESISTANCE, IMPEDANCE SPECTROSCOPY AND GALVANIC COUPLES. ROTATING ELECTRODE AND MICROELECTRODE METHODS WILL BE USED TO EVALUATE THE EFFECT OF SEVERAL VARIABLES ON THE CORROSION RATE AND MECHANISM. THE VARIABLES TO BE INVESTIGATED INCLUDE METAL TYPE, VOLTAGE GRADIENTS, WATER CHEMISTRY AND CONDUCTIVITY, FLOW VELOCITY AND DISSOLVED OXYGEN. THE OVERALL GOAL IS TO DESCRIBE THE CORROSION MECHANISM CAUSING THE FAILURE OF COOLING WATER HOSE FITTINGS ON HIGH VOLTAGE TUBES AND TO UNDERSTAND THE INFLUENCE OF THE ABOVE VARIABLES ON THE CORROSION RATE. THE METALS TO BE INVESTIGATED WILL INCLUDE TITANIUM, STEEL AND COPPER. ALTERNATE HOSE FITTING DESIGNS AND/OR MATERIALS WILL BE PROPOSED BASED ON THE RESULTS OF THIS INVESTIGATION.
