text:  Electroplating is a process which protects and beautifies metals that might otherwise rust or corrode by covering them over with more resistant metals. The plate may be tin, zinc, or cadmium, or it may be nickel or chromium with an undercoat of copper. For instance, as many as 60 or 70 parts of a modern automobile are plated. The 1948 Industrial Finishing Exposition and Convention of the American Electroplater Society opened today at Atlantic City, New Jersey.
