A new method was developed to obtain a new kind of enhanced surface for pool boiling heat transfer.In this method the combined chemical plating (electroless plating) layer was obtained on common metal substrate.The layer was made of metal and nonmetal elements and consisted of polymer particles.By high temperature heat treatment the polymer particles were carbonized to form micropores.The size and density of micropores may vary with the size and density of the polymer particles in the plating solution. It was found that there was a noncrystal metal layer on this kind of surfaces and there were enough ideal cavities on the surface which promoted the initiation of bubbles of nucleate pool boiling.Pool boiling heat transfer measurements were made by using a plain copper surface and the enhanced surface with water at atmospheric pressure.
