摘要
A casting (60) includes a heat transfer surface (80) having a plurality of cavities (110). The plurality of cavities (110) include a density of at least about 25 cavities per square centimeter to about 1,100 cavities per square centimeter resulting in increased surface area and therefore enhanced heat transfer capability. Also disclosed is a mold (200) for forming a pattern (300) for molding the casting (60). The mold includes a surface defining a portion of a chamber (205) to which are attached a plurality of particles (220) having an average particle size in a range of about 300 microns.
