Standard Specification for Electrodeposited Coatings of Lead and Lead-Tin Alloys on Steel and Ferrous Alloys

Importancia y uso:

7.1 Electrodeposits of lead and lead-tin alloys on steel and ferrous alloys are produced where it is desired to obtain atmospheric corrosion resistance. Deposits of lead and lead-tin alloys on steel have shown to have excellent corrosion protective qualities in atmospheric exposure, especially when under-coated by a thin deposit of copper (or nickel). Applications of lead and lead-tin alloy deposits include the following: protection from dilute sulfuric acid; lining of brine refrigeration tanks; chemical apparatus; and parts for storage batteries; and for coating bearing surfaces. In this last application, lead is electroplated alone, or as an alloy and coated with another metal, such as indium. The indium may be diffused into the lead or lead alloy by heat treatment. See Appendix X1.
