Document Format: PDF

Description

This powerpoint presentation begins by providing background information on copper pitting and states the objective of bench scale studies of copperinhibitors as investigating theeffects of zinc,phosphate, andzinc phosphate onelectrochemicalmeasurements. Materials andmethods include:known pittingwater;electrochemicalmeasurements forvoltage,current, andcorrosionpotential. Large scale recirculation rig studies were done to investigate the effects ofphosphate and zinc phosphate onelectrochemical measurements in acontinuous flow system. The study involved a third study to investigate the effects of the followinginhibitors on electrochemicalmeasurements and pit formation in acontinuous flow system:control (no inhibitor);polyphosphate;orthophosphate;zinc; and,zinc orthophosphate.
