Abstract
The invention relates to finned heat transfer tubes and to a method for improving the heat transfer properties in boiling liquids of such tubes by plating the tubes in an electroplating bath containing graphite powder to produce a porous plated surface. The tips of the fins are covered before plating with a non-conductive coating to prevent plating of the tips. The non-conductive coating can be dissolved away or mechanically removed after plating.
