The wettability of a number of metals has been measured under continuous condensing conditions in pure steam for extended periods of time. Water exhibits high contactangles on the noble metal samples studied; the average advancing angles are Au, 55-85; Ag, 68-89; Rh, 65-82; Pd, 74; and Pt, 50. Water condensed in a filmwise manner on Ni, Cd, Ti, Cr, Type 316 stainless steel, copper-nickel 10%, and quartz samples, indicating zero or low contact angles on these surfaces. Experimental evidence relating the wettability of clean metal surfaces to surface oxide present is considered and the conclusion is established that a clean “high-energy surface” of metal substantially free of oxygen is not wettable by water.
