Abstract
The effect of orthophosphate addition (1 mg/L as P) on copper and lead -tin solder corrosion was monitored using an experimental coupon expos ure apparatus with measurement by standing water metals analysis, grav imetric analysis, direct galvanic current metering, and potentiodynami c scan analysis. Orthophosphate addition appeared to have a significan t effect on lead-tin solder corrosion although the results of each ana lysis differed in magnitude. The effect of orthophosphate addition on copper corrosion was less clear with gravimetric analysis showing a si gnificant effects, whereas metals release analysis showed only a sligh t effect.
