Abstract A heat transfer surface for boiling liquid re- frigerant 11 and its equivalents and method for producing the surface. The surface comprises a porous, open-cell coating at least 15 mils thick, of oxidized metallic par- ticles which are flame-sprayed onto a metal substrate. This surface includes a substantial number of nucleate boiling cavities having an equivalent radius in the range of 1.5 to 4 mils, which are the result of one or more of the following conditions in the flame-spraying process: 1) The flame-spraying nozzle is oriented so that the metallic particles impact the metal substrate at an angle in the range of 30° to 75°; 2) The metal substrate is pre- heated to a temperature which is at least 600°F, but below the melting point of the substrate; and 3) The flame- spraying apparatus is positioned such that the metallic particles travel from 3 to 6 inches before impacting the substrate. These conditions create a porous coating with substantially more nucleate boiling cavities of the re- quired size for boiling liquid R-11 than the flame-spraying process disclosed in the prior art.
