摘要：

Tests were conducted using stainless-steel tubes heated electrically from which nucleate boiling took place. These tests were repeated when the tubes had been plated with a thin layer of different materials. Plating materials used were copper, zinc, tin, nickel, cadmium, and chromium. It was found that the presence of the plating resulted in a change in the film coefficient by as much as 200 to 300 per cent in the case of copper or zinc. An analytical solution was obtained for the action of a single bubble on a flat plate. From this solution it is concluded that the effect of the plating material is not due solely to its thermal properties. © 1969.
