Modified process for anodizing 5657 aluminum alloy results in Al2O3 surfaces with infrared emissivities as great as 0.92 and solar absorptivities as small as 0.2. Coating enables fabrication of radiators requiring less surface, and hence less weight: radiators with coating weigh approximately 7 percent less than thermally equivalent radiators made with older anodizing processes. Coating applied easily and economically, and retains all of desirable properties of standard anodized coatings.
