This powerpoint presentation begins by providing a brief overview of galvanic corrosion and the theory of alkalinity mitigating
corrosion by acting as a buffer or by
contributing to formation of protective
pipe scale. Study objectives were to: reproduce this trend under
controlled circumstances;
determine if there is an "optimally bad"
amount of alkalinity; and,
examine mechanisms for the trend -
pH at anode,
chloride concentration at anode, and
galvanic current with conductivity. Part I involved dump and fill jar testing. Part II involved using a electrochemical test cell to
examine conductivity effect. Includes figures.
