Abstract:

A method of and apparatus for anodization uses an electrolyte consisting of 1.0 percent by weight of aqueous solution of oxalic acid, and anodization temperature in the range of 0-5 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 sq.dc. to provide a 30-40 micrometer thickness having a thermal conductivity of 1.3 WattmeterC.
