Thermal Conductivity of Hard Anodized Coatings on Aluminum

Abstract

Thermal conductivities of several commercial hard anodic coatings are measured using a transient heat-flow technique. These coatings were found to be effective heat insulators with thermal conductivities of the commercial coatings averaging 0.7 W/m/K. A laboratory anodization facility was assembled and the variation of thermal conductivity of the anodic coatings measured as a function of the anodization parameters. Preliminary results show that thermal conductivities as high as 1.3 W/m/K can be obtained in thick anodic coatings by optimizing the anodization parameters. Keywords: Aluminum oxide, Electrochemical method, Thermal conductivity, Anodization parameters.
