- Work to determine the relationship between the galvanic corrosion
current, measured by the corrosion cell technique, and the total
amount of lead oxidised (corroded) is reported.
- Further results are presented that support the correlation
between the amount of lead contaminating a sample of water,
containing a solder/copper couple, and the galvanic corrosion charge
generated by that couple.
- Results are presented which show that progressively more of the
metal being oxidised appears in the liquid as the cumulative charge
passed by the couple increases.
- The effects of flux residues, silica, phosphates and sulphate
on the corrosion of tin/lead soldered joints is reported.
