Full Description

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