Anodic coating with enhanced thermal conductivity

摘要

A method of and apparatus for anodization uses an electrolyte consisting of 1.0 percent by weight of aqueous solution of oxalic acid, an anodization temperature in the range of 0 DEG -5 DEG C., and an anodization voltage starting at 100 volts and progressing to 300 volts after 90 minutes at an anodization current density of 2-3 amps per decimeter2 to provide a 30-40 micrometer thickness having a thermal conductivity of 1.3 Watt/meter/C.
