Gold Surfaces for Dropwise Condensation

Gold surfaces were investigated as promoters of dropwise condensation of steam at atmospheric pressure. Seven gold electroplating baths, one electroless immersion gold plating bath, and vacuum gold vapor deposition were used as deposition techniques. Five different surface preparation techniques of a pure gold sample were also tested. Gold deposits ranged in thickness from 100(ANGSTROM) to 20,000(ANGSTROM) with major emphasis from 200(ANGSTROM) to 5000(ANGSTROM). Auger electron spectroscopy and scanning electron microscopy were used to describe the heat transfer surfaces chemically and physically.
